More info to come, but wanted to let everyone know that I'm going to be at Fully Charged Live in Austin, TX this coming February. If you want to go, use code UMF2019 to get 15% off your ticket. Hope to see some of you there! bit.ly/FullyChargedLive

Its fine! Just move closer to work every year

I've had my Model 3 for about 1 year. A software update increased the range some, which more than compensated for any degradation. Over that one year, the range increased from 310 miles to 315 miles. So I'm not worried. Something to keep in mind: battery replacement is a thing that happens years in the future (else it is covered by warranty) and the future tends to be different than the present. Battery tech is rapidly improving energy density (range), power density (acceleration and recharge rate), and cost. So even if I need to replace it in 5 years, at that time it will probably only cost about $2,000, and that price would probably buy me an upgrade to a 400 mile battery that would never need to be replaced again. Incidentally, I recently performed the annual maintenance all by myself. And me not even a mechanic! I'm very proud of myself. This consisted of adding windshield wiper fluid and topping off the tire pressure to 43psi.

I have a second hand 2014 model S 85. And the battery is fine . I charger it no more then 78 % and I get 285 km or so Recharge between 60 and 80 km . as the man said just enjoy it.

I set my M3 to percentage instead of kilometres. Problem no longer visible....

Great video Matt. I been following you for several years & like your content. I just did a battery health check (winter months) on a 2018 M3PD & my battery life is now around 86 to 88%. Was getting 309 originally now at 289 to 291. Vehicle only has 33,000 miles & mostly charge on level 2 Tesla home charger.

Charge it, drive it and enjoy. "your mileage may vary" It will last a long long time.

Seriously! We purchased our Model 3 LR AWD 6 weeks ago. Already 5000 miles on it up and down the east coast. Love it. Coming from a Mercedes C300 the Model 3 is not a perfect car but the pros faaar outweigh the cons plus its an EV. The way I look at it, with Teslas recent acquisitions and current advances in battery tech, in 8 years there will be a substantially longer range battery at a lower cost that we will want to buy. Great source of info Matt. Thanks for your channel.

Great video Matt as always. I always enjoy your data first method and you don't hype it as others do. As a Tesla Model 3 owner and Nissan Leaf owner I find myself keeping an eye on the Leaf SOH% quite often but the Model 3 not at all. I'm in FL and the Leaf's don't do well when the packs are at 115F like it gets here during our 9-10 month summers. It's funny we really love the 2012 Leaf and know the end of the road is coming, sometime, because it's inevitable. But never think of the Tesla in that frame of mind. Keep up the good work!!

I’ve switched over to percentage instead of miles and I haven’t looked back. I have faith the battery will do fine. I also don’t do a lot of long road trips where I need to worry about how many miles I can go. Appreciate the info and data.

Hi, love the channel!! Just wanna tell my story...bought a 2019 Model X 100 kw on March 30, so I just missed the Raven battery upgrade (this will become relevant). November 19, this year, our cars main battery died...luckily near a Tesla Service Center. We are on our way to pick up Red 5 today (Model X Name) after driving a very cool Model 3 for a few weeks. They did replace the 100kw with a Refurbished Raven, and explained the warranty will continue just as if it was the original. In my experience, dealing with the Sevice Center team has been amazing. They have kept us informed on time-lines and answered questions. Professionals at every level. I know of no other car dealers who will give "loaners" out the way they did...I am cautiously optimistic. But as you stated in the video, willing to sit back and enjoy our car! And your videos;)

My model 3 awd lr is down to 260 miles on a full charge. Not happy with that. Only 6 months old

Would be interesting to see how the loss of battery capacity in EVs compares to the loss of fuel economy in ICE cars over time as their engines and transmission age.

How many of you unplugged your phone while watching this video 😂😂😂

This is bar none the best model three channel that there is! Big thumbs up here👍 being that I have a standard range plus my range anxiety started getting out of control once a full charge only said 229 miles three months into ownership then I switched it over to percentage and just watching it pattern wise over time it makes a lot more sense on the percentage part that’s what I would suggest everybody leave it on. I switched it over to miles for fun And put it up to 100% and this morning for months after switching to percentage it’s at 231, I will keep it on the percentage from now on range anxiety gone

Hi Matt, 2023, I recently purchased a very nice 2015 Model S 85 with only 35,756 Km (23,000 m). The car has always been AC charged to 85% with only 2 superchargers in its life. I drove to my holiday house 112 km away started with a charged range of 346km, drove to the H/house and still had 244km range. The car is in near perfect condition and I simply love it. The only problem it has is the max AC charge rate is 16 amps. I will have this rectified in 2 weeks to raise this to 32 amps.

Thanks for the video. Didn’t know the degradation flattens out. Range is a much bigger concern for those of us outside of California where most people who make these videos seems to live. My now 300 rated range is more like 200 in the winter. This is problematic for long commuters. If my battery gets below 90% I’ll have to start doing full charges just to make it through the day.

Model S and Model X owners have had the benefit of Stats almost from the very beginning. A great app!

I think what people forget is that I.c.e also go through this reduction in range, despite lubricants added to fuel. Many gas and Diesel engines see a similar percentage loss in range due to fouling, air filter clog, oil and any number of other items associate with a purely mechanical means of transportation. This also reduces power over time which e.vs have not been show to suffer from ,yet. So it's worthwhile keeping perspective on matters. From a gas car owner.

I’ve lost about 6 miles (down from 310 for the performance version) after 33k miles. According to that Stats app. I only charge to 90% daily. I’ve done a handful of 100% charges on road trips. I also rarely supercharge. But I didn’t loose any ranger til after 11k miles. I’ve put 33k miles on the car in about 1.5years.

Not worried, enjoying the car, it's amazing! I do track mine closely as you do, love data!

I have been looking into a plug in hybrid. In my area in Canada the fast charging infrastructure is so thin that a round trip exceeding the range of an EV would require planning by chargers, not by where you wanted to go. That being said I looked a lot into batteries for EVs. I found basically everything that this video says. I also found that a typical Li Ion battery is good for about 400 cycles regardless of what it is used for. In some of Matt’s other videos he has talked about how far Tesla battery technology is ahead of the competition. But if you look at their warranties, they show no such confidence in their superiority. Taking the Canadian warranty for total km and the advertised range per charge, the Model X warranty is equivalent to 440 full charge cycles and a Model S to 380 full cycles. Basically the same as the 400 cycles typical for a cell phone battery. It all comes down to battery oversizing and charge management. There may well be some incremental improvement with respect to other battery design, but not stellar technology superiority. If fact, if someone drove a Rav4 prime exclusively on battery charge, they would need 3,900 full charges. While that seems silly not to take advantage of the hybrid mode for longer trips, there are certainly KZfaqrs who claim they only use one or two tanks of gas a year. Not sure if this will be an issue for Toyota in a few years, but anyway you cut it, the Toyota battery seems to have a stronger warranty than a Tesla.

I've owned many rechargable battery appliances: lawn mowers, weed trimmers, cell phones... And they all begin to lose ability to hold a charge, after a year or two at most! So I've learned to avoid rechargable items whenever possible.

as my name is my job, i can tell you that those people saying bad things about EVs are all 100% true. it costs a small fortune to replace an EV because you need a special license, tools and training as the battery is considered high voltage where one small mistake can kill you. the batteries are lithium-ion just like your cell phone battery which no longer is able to hold, maintain and recharge after about 4 years of use which most people dont notice as they keep their phone until the contract runs out and get an upgrade after 2 years.

43,000 miles AWD model 3 (OCT.15, 2018) Stats efficiency 101% better than 87% of users. I drive every day and plug in every night charging to 80-85% long trips 99% still handles like a brand new car no annoying squeaks even with listening to music at high levels all the time. It is a privilege to drive everyday. Still learning things and surprises in updates all the time. It’s crazy , most dependable car I have ever driven.

Thanks Matt for another great video. My M3 range seems to fluctuate depending on software updates and how I've been driving it. My first electric car, a Nissan Leaf, it's range was all over the place. Just charge, drive and enjoy.

My 2013 Tesla model S battery died at 106,000 miles and will cost $20,000 to replace. That’s 19 cents per mile + electricity costs to run my car. Considering at $5 per gallon a 30 MPG car only costs 16 cents per mile, there is no way my tesla was more cost-efficient than an ICE car. I loved my tesla but I am over it now. I’ll buy from a better company in the future. Prove me wrong Matt.

I think the Nissan Leaf is responsible for all these battery fears. No thermal management spelled early doom for there batteries.

Hi, great video! I was wondering how you would handle long periods of leaving the car parked and how it would effect the battery. I travel for work and am often away for a month at a time. Would it be better to leave the vehicle plugged in and set it for 70% charge, or something like that, or leave it unplugged? If I had a preset charge limit, like 70% for instance, does the charger keep maintaining to that limit? Thanks!

Love your well-balanced and sensible approach, Matt. Keep up the great videos!

Range loss is not the main issue for large battery packs. In Tesla's thousands of cell architecture. One cell failure disables the whole pack. Tesla (and all other EV manufacturers) is charging $20k to replace the high capacity packs. They don't make disassembly, finding, and replacing a sub module (or simply disabling) the single failed easily. And it is dangerous facing the high current 400V battery that can kill if not careful. I have a 2013 Model S, lots of 12-13 MS owners facing this now. Cost is $20k post power train warranty. M3 owners are still in honeymoon period under 8 year power train warranty.

My 2013 S85 with ~85K miles, rated for 265miles, just saw some degradation last year, and the new range estimate is 255miles (or -5%). About once a year I make a NM-NH-NM roundtrip using superchargers, discharging down to between 5 and 20%, then charging back up to between 80 and 100%. The rest of the year it's home-charged (240V/40A) to 70% for local commuting, which is 40-50 miles/day. Not sure what the SoC is when I plug it in at the end of the day, but probably around 50%. A few times a month I make a trip to a town about 80miles away, and I'll home-charge to 80 or 90% to make the roundtrip comfortably. I have no range anxiety, no concerns about significant range loss, and will never buy another ICE vehicle. Just one mans experience.

Matt, I have a LR AWD M3, I also have the stats app and it is showing a 'Rated Range' of 290 @ 11 months and 13,828 mi, which seems pretty a hefty 20 miles in only 11 months, that's a whopping 6.7% loss in less than a year. @6:10 according to your graph I think I should be @ about 300(3.1% drop) but my 290 is a 6.7% drop. I have 're-calibrated' 10%-90% several times and reset what I could, but none of this does anything for me. On an average day I use only 10% charge as I live close to work, so I only charge every 3 days or so, normally keep SoC between 30-80%. Battery has never seen over 90% charge, Tesla came out and hooked it up to a computer and said the battery was fine but to me its dropping pretty fast on the stats graph, about 2x what your getting (3.1% vs 6.7%) in the first year. Feel free to correct me if wrong. :) Home screen on Stats (Graphs) www.dropbox.com/s/ra1flsrjvwc80d4/IMG_0015.PNG Battery Health graph www.dropbox.com/s/ly77coswapywo2o/IMG_0016.PNG

I know someone who is driving a Tesla for 5 years now and the battery is going great so far. Only loss @8 miles.

Our Model 3 | LR | AWD | Dual Motor | FSD was rated for 358 miles on a full charge. We often charged between 88-90% (320-325 miles) exclusively at superchargers during the first year. After eight months or so we noticed a drop in range to 310 miles at 90%. The second year, we began charging exclusively at home, and even at the beginning 8,000 miles later, noticed we were getting 301 miles at 90%, and when we charged to 100% (rarely) it read 325 miles. Approaching into our third year, driving a bit more and closer to 20,000 in total miles, charging to 90% reading just below 300 miles, fluctuating between that and 294 miles… One of the main reasons we chose the Model 3 Long Range was due to the rated 358 miles estimated, knowing that elevation and consumption of the other features of the car would ultimately affect the battery drain. My only real concern for the future is, hoping that a battery replacement would cost significantly less, and the technology would also be considerably better when that time comes. Our intention is to keep the vehicle for at least a decade or more. That way we have a better understanding of the real cost of ownership compared to previous experiences with ICE cars… 🤔

SR+ owners to me! I charge to 90% and my rated range has dropped to 203 miles of its rated 250. At no degradation I should be at 225 miles@90% or 213 after 5% degradation. My battery has degraded nearly 10% if I go by the rated 250 and over 5% if I go by the old 240! And this is after 5 months and just under 7k miles! Am I an outlier or is this similar to you all? I thought it was due to how cold it is outside (30-40 in the morning when charging, 50-60 when driving home) But we had a freak 3 days where it was 70 all day and night and my range never budged, what’s going on?

I thought the most often asked questions was "where is your Decided and Deciding channels?"

Once again Matt, thank you for your invaluable insight into EV and general battery management. Your in depth research is in a class of its own.

Here on KZfaq is an Uber driver who only get 110,000 miles on his Model 3 battery before it failed. He was driving 300-500 miles a day and supercharging twice a day. He was faced with a $12,000 bill and loss of income. There is a Million mile S which achieved that but required 4 battery packs and $30,000 out of pocket for 2 of the replacments -one came with the car one was covered by Tesla in warranty. How you charge; and weather conditions you charge in make a lot of difference to longevity.

My dual motor Model 3 has about 9K on the odometer. I have no idea what the estimated range when charged is. I used to leave the little energy indicator on remaining miles of range but it made me nuts so I just changed it to show percentage. Now I really don't worry about it. I just looked at the Stats App and I would say that mine is right in line with the norm as I have theoretically lost about 5 miles of range. I have been a little bit surprised by how much running the cabin heater crushes the range. I shouldn't have been surprised as I had read about it but to experience it in real life it hits home. I drove for a few days without using the heat and only using the seat heaters. Then I realized how stupid it was to not be comfy and decided to just drive and enjoy my car. I mean I only have a 72 mile round trip commute and usually only 3 days per week. I am still saving a fortune on energy vs my pickup truck.

Your videos are terrific.. I have the long range AWD. As I do not charge at home, I head to a Super Charger about 7 miles away when I get down to about 28%. I have had the car almost a month and have driven 600 amazing miles. I do some new sailing yacht brokerage work in Marina Del Rey CA, 25 miles each way and commute there about 3X per week when I am home between tours. It consumes about 12- 18% rouind trip depending on traffic. The way back is the bad boy with an hour and a half or more drive time.. No sweat in the Model 3 though. There seems to be more and more model 3's here in CA. I took advantage of the 2 year unlimited charging + 2000 free miles (so far) after that. The Super Chargers that I have been to are located in really great shopping and "hang outs", where you'd wish it took a little longer to hit the 92% that I set, providing 90% when I arrive back home. Oddly, sometimes the Super Chsrger initially indicates a 2+ hour charge time! I move to another stall and it changes to the average 45 minutes. Wouldn't mind a bit longer (than 45 minutes), as I like to enjoy a nice 🍺! A Super Charger is opening up in Pasadena real close by in 2 weeks! Here in Southern CA, Chargers are conveniently located at nice places all over. Great excuse to step out of the house at night, relax and enjoy this amazing technology on wheels. I hit the road soon again for of my real gig as a musician. The red Model 3 will be my "tour bus".. Was notified by the State that they are sending me a check for $2500 because I bought an EV!. It keeos getting better... I can send you some 6 and 12 string acoustic guitar pickin' tracks (free), that you or anyone else reading this can intergrate however you'd like in your videos. Let me know.. All the best and keep up the nice work.

What we all forget is all cars degrade overtime. A gasoline/diesel car's engine generates less horsepower as it ages. It also loses range as it wears and ages. One might consider thinking about how much an engine would cost to replace just as much as you might want to know how much a new battery would cost. The only thing I know is both are expensive.

E cars are a class divider. Only people with a garage own them generally. Those in a condo or apartment are barred entry. This is a barrier for general acceptance. They will remain a niche product for the relatively well off for the foreseeable future.

I bought my model 3 in jan 2020. I remember charging it to 100% just out of curiosity the first week, it never reached a charge greater than 305 miles. Two years later, after consistently charging at home to no more than 90%, rarely using superchargers (been using them more the past 2-3 months), my range is 254 miles at 90% (268 less than 6 months ago) close to 275 miles at 100%. I keep hearing people saying “oh forget about that”. “Not important, just a calculated range”, yet i can see that the range is less and i have to charge it close to or 1 day earlier than before. Tesla owners consistently report a battery degradation after 50k-100k miles that is way less than this.. If this is not battery degradation, then what is it? My charge habits are not terrible. I hear all kinds of things about battery recalibration… is this something i should try?

I enjoy your videos, they are very thorough. I am also very data driven when I make decisions; perhaps not as detailed as you though. I have had my model 3 since April of this year. Although I did a lot of research, I was not prepared for the battery drain at night, during cold weather. I have worried a little about battery degradation, but charge up to 90% every few days, and never go below 30% charge. I have stopped worrying about my model 3 constantly at this point and enjoy it a bit more. Although I don't worry about it that often, I still think about it often, it's charge state, configuration state, maintenance, and sometimes long term battery degradation issues. In conclusion, I believe that my model 3 will last anywhere from 10 to 20 years, or however long it takes to get to fully autonomous ride-share technology; by that point, it won't really matter how my model 3 is doing.

Tesla Model 3 Performance, Delivery October 2018. Stats from TeslaFi for my vehicle: currently at 44,685.79 Miles, 2.33%-3.08% degradation of the battery. I live in Pennsylvania (travel a lot to North Carolina and Florida, sometimes to Colorado), charge my vehicle usually to 90%, charge approximately 66% of the time at Tesla Superchargers as I drive a lot of long distance, 34% of the time I'm charging off AC whether at my house using the Tesla Wall connector at 240V and 48A, various J1772 chargers, rarely but some 240V sources, and even 120V 12-16A depending on what is available when I'm traveling. I keep my car plugged in whenever and wherever I can to some kind of AC source. I drive 99% of all days at least a few miles, sometimes a lot. I charge to 100% approximately 5% of the time when I know I'm going on a long trip, and occasionally hit 100% at a supercharger late at night when I'm sleeping in my car but that's infrequent.

You forgot to mention heat degradation. Tesla packs are water cooled and heated which helps a lot. Just look how bad the degradation of the Nissan leaf is without thermal management systems.

Hi, you didn't address my worst fear: the cost of a battery swap after 8 or so years. The thought of paying upwards of 20k each 8 or so years to change the battery scares the shit out of me, honestly. This should be addressed very specifically, and not just casually mentioned for five seconds. Thank you.

I charge my standard range + at 80% on 120 volts everyday (except ocasionnal supercharger) so the battery should be happy with that and I dont worry too much about degradation

I agree enjoy driving your Tesla and leave the haters to play amongst themselves.

Please make a vid about battery drain. I use my car only once a month. The other days it’s just standing around on the curb. When I leave it there with 80% charge how much is left for me to use after a month or say 3 weeks.

My LR RWD shows 309 at 25,000 miles. That tracks with your graph. The car was sold to me with 310 rated, so I've only "lost" 1 mile. That disregards that my car was changed to show 325 miles back in February 2019 and has since decreased back to 309.

Great video! My biggest gripe about the Model 3 comes down to Phantom Drain. Now that we are in the winter, I'm using 50% more charge than I did during the summer and also doubling the phantom drain every night. My Model 3 has gone from the efficiency of a Prius, to the efficiency of a Ford F-350 in terms of mileage on a charge (about 55mpg equivalent at $2.59 per gallon @ .22 cents per kWh to < 20 mpg). More or less, I'd be better off driving my truck in the winter as it is more fuel efficient than the Tesla with the insane Phantom drain. Just my humble opinion of course and everyones cars are different but an ICE engine costs you nothing when its turned off and my Model 3 is costing me a few dollars a day just in phantom drain when its parked in the driveway doing nothing. I wish there was a way to power down the Tesla when not in use similar to turning the key off in an ICE vehicle.

I really gotta know: does a battery pack at say 200,000 miles that is "depleted" to 80% original capacity require only 80% of the original amount of energy to charge it? Or is it that much less efficient as a storage medium, requiring the original amount of energy to charge it? Thanks in advance (I don't own an EV - yet).

I love this video, i love that you show us the study and graphic and not only say it like “there is a study blablabla”

I'm driving a KIA EV6. And yes, sometimes I do worry about battery health, since it's a lease and I think of the value of the car in about 2.5yrs when I need to give it back. So far I really do enjoy the car, though I'm still open to having a Tesla Model 3 as my follow up car. We all have to think about driving more conscious with our battery health in mind and how we recharge. And yes I know that people behaving very differently when charging their phones, like whether you have the time to reload vs. it need to reload. I can set my car to only charge up to 80% and that's what I do most of the time. And usually I do not drive it below 20% of charge. Some people say it's best for the battery to be charged between 20%-80% ... others say 30-70%. That was reason enough for me to go for the big battery rather than the standards if the only usable charge is between 20-80%, which means it's just 60% of the battery. Even if I get me a Tesla Model 3 I'd opt for the extended range model.

Thanks Matt, great video. There is heaps of evidence out there that people are worrying far too much about this issue. Even Tesla batteries which are hammered with very high mileage and lots of Supercharging are holding up very well.

This is my 5th EV. I've driven well over 300,000 miles on electricity. I thought the Leaf dropped range quickly, but my year old AWD LR (13,000 miles) is winning that competition. It isn't just the range estimate that shows about a 10% drop, it is ACTUAL RANGE that has dropped. I can no longer make some of my regular drives without a mid-way charge. I drive the car well above 100% efficient (meaning lower Wh/mile that would be required to reach 310 miles), and I still can't quite make 280 miles. My lifetime efficiency average is just under 230 Wh/mile. I've supercharged exactly once. I typically drive it no lower than 30% and charge no higher than 90%. Usual the car stays within 50-75% SOC, but several times per month I drive lower and charge higher. I've charged to 100% a few times for testing, and have driven it down to 12% SOC and calculated the range from there. I used to achieve over 310 miles. Now I can't get 280 miles. The car and Stats report 280 miles as full range. And Stats tells me that my efficiency is better than 97% of Model 3 drivers. So in summary: I'm experienced with EVs, I drive efficiently and I'm nice to the battery. And I've lost more range than almost everybody I've heard about. I have friends and family with the same car of the same age, and they abuse the hell out of the battery (charge to 100% and let sit for days, drive the car down to 0 SOC) and the most they've lost is ~ 2% in the timeframe and miles. As this is by far my most expensive car ever... yeah, it does worry me that it's losing range so quickly. Especially after the solid track record of the Model S, and where the 3 is supposed to have even better batteries than that car. I honestly thought this battery would lose capacity slower than the S. Boy was I wrong. Tesla tells me that it is fine. And then reminds me that driving fast can consume range quickly. Gosh, thanks Tesla! Never thought of that. (Battery compare tells me that my battery's capacity is better than a whopping 2% of the drivers. That was a depressing way to spend $2.99).

Good video. Nothing to add. I can share our 90kw battery, the model x p90dl first would charge to 257 miles. After 3.4 years and 48.5k miles we now charge to 236 miles. So we lost 21 miles and we are doing fine with that. One day I will want to swap it out for a new one and hope we can get a 330 mile new battery. Maybe in a few more years..

I'll have to comment on this one. I drive a Chevy Bolt, and am just enjoying the car. I have seen very little degradation battery wise. Also, I have been a licensed Master Mechanic for over 40 years. I will point out that gasoline driven cars also lose gas mileage with age and many things on a gas motor wear out constantly over 75 K miles and many times much sooner. Brakes for example are a constant headache; where on my EV, I rarely ever use them. So all cars degrade over time. I'm not worried about EV's. They will replace all our old out of date gas cars within a few years. Keep the good information coming Matt. I'm 77 years old BTW.

Most valueable: Enjoy your car!

Amazing like usual.

Mine is a 8 month old MY with 9,900 miles on the clock and from 326epa went down to 306miles 100% charge. Tesla did a virtual diagnoses and told me that my battery retention is at 90% and I lost 10%. I asked them why I lost 10% for such short period and I’ve been followed what the manual stated in how to charge our car. Now the virtual tech rudely told me “if you have questions then I will schedule you to visit the service center” so now I have to bring my car to service center this coming march.

Thanks for the videos. Have a 2014 Model S. Rarely charged it to 100%. Probably 80% or less most times. I have charged it 99% of the time on Superchargers though. I have nowhere else I can charge. It was a 265 mile 85 and still charges to about 242 last time I checked. Hammered it for the first 6 years (badly), then during lockdown things changed and I now do 100 miles a week max. The worse thing about the car? New wheels and tires. I have a knack for hitting LA potholes on the freeway in the dark. Buckled so many wheels and destroyed tires. I now have to carry a spare and 3 ton jack. Got another flat two weeks ago. Would not go anywhere without a spare.

Just a couple of points. 1) It is not holding the state of charge at 100% that causes the damage, it is taking the battery to that level in the first place. I've tested this by leaving leaving a cell at 100% for 6 months with measurable difference from the control cell that was stored at a 50% state of charge. A cell left for 6 months at a zero state of charge had lost 15% of its capacity. 2) Tesla does not leave a buffer at the top (except for the software capacity limited vehicles). 100% is 100%. They do appear to leave a small buffer at the bottom. Zero is not Zero. There are some KZfaq videos where people have driven their cars until they stop and invariably this is many more miles than you would expect. However, don't depend on this buffer to save you! It is hard on the battery, probably the worst thing the car will allow you to do. 3) You allude to this in the video but the rated range is just a number that Tesla is telling you. They can make it say anything they want. If I understand correctly the rated range is for driving on level ground at a constant 60 mph under ideal conditions. Low temps, headwinds, road surface (wet or rough) will all adversely affect range but this is not reflected in the rated range display. If they decided to they could double the rated range by changing the speed to 30 mph. I've driven my model S almost 90k miles in the last 4 years and I appear to have lost about 0.5 % per year. I have only taken it to 100% three times on road trips where the next supercharger was more than 200 miles away. My normal charge in the summer is to 60% and in the winter to 70%. This keeps me centered around the 50% point which appears to do the least harm to the battery. I drive less than 40 miles per day unless I am on a road trip which is why I charge daily from a 110 VAC outlet in the garage. On road trips I supercharge pretty much exclusively and have done so for probably 60000 of those miles. At my current 0.5% per year degradation I expect 20 years of life from the battery if 80% of original range is the cutoff point. By that time it should be easy and cheap to recycle the battery and put in something a lot better. Thanks for the Video and drive safely everyone!

I’ve lost 5% in 7months & 5,000 miles on my midrange M3 and I’m concerned mostly on re-sale value. Particularly if I sell sooner than later.

I haven't lost any range after 12k miles. Might also help that I do the majority of charging on the ol' 110v 15A outlet. Just 4 to 5 miles of range per hour but it's enough to cover my 70 miles a day.

I always bring up the warranty, but something else that you didn't mention is the fact that the price continues to drop on lithium batteries so that when 8 years comes around, replacing the pack will be considerably less expensive. That, plus the fact that electric storage technology continues to advance - as evidenced by Tesla's purchase of Maxwell - such that by the time the 8 years on my warranty expires, they may already be on to new kinds of electric storage that is more efficient and cheaper - hybrid dry-cell and supercapacitor packs.

Found this useful. I’m a new owner and hav seen my battery health (per Stats) drop about 10 miles in only 2500 miles. I’m also in the low percentile (8) compared to others.

I wonder how much of a effect using the super charging stations have on the battery packs ?

Great Video, and Great data! Another thing that makes me excited for the Tesla roadster is the fact that the battery is twice the size. Not only does this double range, but it decreases the load per cell, therefore making the battery degrade slower and discharge more efficiently.

I might have missed you saying this, but what I can understand is that the number of charging cycles have a great impact of a lithium battery's lifespan. A smartphone you might use up the energy stored in the battery every day, but to use up the energy stored in a EV battery pack like Teslas you will need to drive extremely much, that is something like 400-500 km a day (248-310 miles). Because of this reason the battery pack in the EV will last many years more than the battery in your smartphone.

Excellent video-I have AWD model 3 and model S 85 -2013 -I have over 132k miles on the S and degrade is very small -amazing how well these cars hold up. The 3 is an efficiency hound -I think early in cars life anxiety is high the longer you own it the lower that anxiety will be. Great cars -excellent service-very tight -they just work over and over. Relax and enjoy the ride. :)

"Current Battery %: 69" Me: "nice"

I started my Tesla journey with an 2015 85D MS. The 270 mile range degrated 8 - 10 miles until I sold it in June 2019 to purchase a long range Model 3 dual motor. The primary reason I did this was the new and bigger battery. I have a regular trip of 395 miles that in the MS was two charging stops and in this car was to be one. When I started with the M3, it made the trip easily in 1 stop. Now, the car is struggling to get the long leg completed in one shot. I've seen more degredation on the guage (310 miles at start to 296 miles now) than I did in the almost 5 years I owned the MS. I will continue to monitor but I'm very worried that one of my primary reasons for upgrading is about to be no longer true.

Maybe I"m an outlier but I don't believe that people should stress themselves over squeezing every last drop of possible longevity out of their batteries. (Obviously follow the manufacture recommendations since you want to keep your warranty) Battery research and technology is advancing so rapidly these days that It's very likely that in 5-10 years time you will be able to purchase a new pack that is significant better (more range, faster charge, more robust in all conditions) while also being much cheaper. Swapping out your pack will probably be a desirable upgrade regardless of your state of degradation.

Love to be able to capture stats on my Kona when it arrives in a month, also on Android. Any way you can recommend to do this easily?

You may be the only one who’s range went up after the v10 update . I have like 20 friends with a Tesla & all seen a decrease of at least 3%

It will always depend on how you drive it! If your Punching the pedal then your range will shorten, if you drive as if you want the most range, meaning you brake earlier so that you get more out of regenerative braking, are you using hills to your advantage, and coasting or hypermiling. As I said it depends on how you drive it, there is no way I would allow it to ever get down below 40%, unless it was for an emergency! Also if you charge it slower you also get more range out of it. Especially if you charge at home! Resonance Induction Charging will be out soon and none of this will matter anyway! Because no one will be going back to charging station when 60% of roads are charging your car during most of you drive!

11:01 so I have a 2023 polestar 2 performance pack 476 HP and range is a constant concern as I have a 150 mile round trip commute. I have yet to resist the urge to fully charge before leaving home and work as I have level 2 chargers at each. I only hope that polestar releases some over air updates which add some miles to the range over my tenure wirh rhe car as at 260 miles (more like 220) is not ideal. I chose it mostly because of the looks performance build quality and there are just so many Tesla 3s on the road :-) thanks for the video

Even Elon Musk said that charging to 90% is no issue

Matt, please go back to the old intro music. It was so nice and comfy.

My Model 3 Long range performance with 12k miles on it charges to 269 miles at 100%. I think i'm a major outlier on the down side :-( I've done fully battery cycles. Charge to 80% every night. supercharged only about 10 times. Tried charging to 90% for a month. Just keeps going down.

It's been 3 years since you said anything about the battery in the Tesla. I know your busy with lots of new things. But if you get time could you give us another update on how the battery is ageing. I would like to get an EV as I think I would like it. Being retired, I only drive about 4k miles a year and my typical trip is less than 20 miles round trip. I haven't seen anyone else post anything on low mileage battery degradation. Maybe talk about how to treat a battery that doesn't get a lot of use. Thanks for all the information you post, I really like the videos.

When my 2015 Accord is in the shop for maintenance I have been renting a S from Enterprise since I really would like a Tesla (3 not S since the 3 has more features). During my most recent rental I changed the battery display from range to percentage. My Accord's gas tank gauge has "F", "50%" and "E" and depending upon how I drive a tank can last me 640 miles (99% highway miles, after five years of ownership at 145k miles). I just look at how many miles I have driven since the last fill up and figure out how much remaining miles I have. Why not do the same with an EV? I would be curious if one sees the same range fluctuations (down to 20% remaining and I drove X miles since the last charge) as when the battery is showing the estimated range.

Matt, I like those fact based videos...keep on the good work...

Great video Matt. Question for you.......Do you think it matters how fast or slow you charge the battery in the car? Do you the car likes a high amp fast charge or a low amp slow charge better ?

People like you and Bjorn Nyland gave me that last push into buying a model 3....since I bought it I immediatly discovered the biggest impact on me personally...there is no way back now....I will never be able to go for an ICE car again....ever...the car is simply as good as they say, didn't regret buying it for a sec (at 10k km atm).

You are forgetting once you hit the half-life of lithium ions. Even with not many cycles the battery will begin to rapidly decline. So the slope of that graph will eventually get much steeper.

I charge it once a week . Is it so bad for the batteries?

The cost you save on using petroleum based fuels is lost by the cost of replacing the battery pack.How do work this out before buying an EV. Also here in the UK the cost of installing a socket is I have heard is £2000 and you are able to buy a lot of fuel with that money.The other problem is there’s rows of terraced houses on both sides of very narrow streets and when cars park they are half on the path and on the road.So when you come to plug it in the cable if it reaches the socket will be going across the footpath and people will be tripping over it,especially at night.The other issue is if you are renting who pays for the installation the Tennant or the landlord?If the tennant moves they cannot take the socket:installation with them and means they will have the cost of installing another socket in their next place of residence.Is there any way of charging the EV by using WiFi which is converted into an electrical current to give some charge to the Battery pack.Other than that be able to use a normal three pin plug,socket and adapter to charge up the vehicle 🤔❤️🚗🚚🚜🚓🚑🏎Ps:What are they going to do with all these petroleum based vehicles across the planet?has any one added them all up?Will there be some sort of conversion from petroleum to EV.If so what happens to all.these Engines?

My M3 is just 4wks old and while I have it on miles rather than percentage, I am not actually tracking it. Just observing how my driving, the weather and phantom drain affect it. I'll be switching to percentage once my curiosity is satisfied. I've followed Tesla closely for about 4 years now and trust their tech & their commitment to their mission statement. A car built for 1M miles & a battery built for 400-500K miles, and amongst the safest in the world, who can go wrong with buying into that!

Change the battery meter to percentage and don't worry about it.

Very interesting and data-driven to boot. I find myself being one of those who “top off” my phone every night. As an electronics technician for forty years, I know I am negatively impacting my phones longevity, but I balance that against the comfort of knowing my phone is fully charged when I need it to be. If only I could train myself to keep it between 30 and 70 percent (I’ve also heard 80 and 20). I don’t have a Tesla, but I’ve been exploring the idea of buying used Tesla battery packs to build a DIY power wall and I’m seeing that replaced battery packs are still producing more of their rated output in KWh than their mileage would indicate, something like at least 80% (about the lowest I would buy, and then only at a good deal) and usually over 90%. This is from 7 year old battery packs! So, I’m pretty comfortable that the typical EV is going to have a battery life at least as long as the typical internal combustion engine can be expected to last, and that’s okay with me. BTW, I used your link to Energy Sage, and I’m in the process of getting solar panels installed on my roof. Energy Sage really helped me find a contractor that I can work with! So, thanks!

Hi, great Videos! have driven from 0 to 18K in 15 months (T3 dual Motor Long range). I live in Northern Illinois and was consistently getting almost the rated performance until around November, when I took off the Aero wheel caps. Then the cold weather hit and for the last couple of months I am getting (rough calculations) around 20% less range in use (I use the energy % indicator mostly). The trips to Chicago and back that I used to be able to take with a 80% charge (with 10% remaining arriving back home) now needs a short top off at the superchargers at the destination. I think the very cold weather has a lot to do with most of the degradation (although Tesla assures me I am losing 10% due to not using the Aero hub caps). Any thoughts/ data you have on Cold weather performance (and Aero wheels) that you wouldn't mind sharing? Thank you. Keep up the good work.

Concerned...2019 LR AWD Model 3, nearly 3% loss in 3 months. Down to 270 at 90%. Never charged over 90 and never fell below 30%. Currently at 5,000 miles.

spent 11 minutes and didn't answer the question...nice job

Why would I worry? It doesn’t change anything. I love my M3P! It’s fast and fun to drive plus I’m a subscriber so I’m counting on you to keep me informed.

I bought my used 2018 Model 3 Performance in July with 4600 miles on it. Since then, I've put about 10,000 miles on it. I started using TeslaFi around a week after I bought it. The battery degradation report for the first month and a half I owned it maintained around 310 +/- 0.2 miles.. Then in mid-September, one day, it suddenly dropped about 3 miles. Then a few days later it dropped a couple more. I'm currently at 299 miles of range and the degradation over the past 6 weeks looks like a staircase going down. I only charge to 80% and have been daily charging. I recently am trying to let it go below 50% before attempting to recharge to 80% and hopefully it stops going down.

Hey Matt, another informative video, thanks. I'm back on a quest to find an answer to a question I've had every time the weather starts turning cold. My question to Tesla has basically been at what ambient temperature should I start worrying about preconditioning my battery before usage? Over the last three years I've never received an answer to the question. My latest conversation this month with Tesla Support yielded a new bit of information. You should know the temperature of the battery. Great...how do I get that information? You can't, only we can see that number. My reply.....Is it a big secret? Tesla's standard answer to my question over the years has been...when the weather turns cool, charge your car every night and turn on preconditioning. My question to you is...... Have you come across any app from a third-party vendor that presents additional telemetry from the cars concerning the battery's temperature? thanks
