I like your idea! Yup, I'll certainly do that in the near future!

Thanks for dropping by and watching! I always replace the screen adhesive on all iPhones that started having them. Thanks for your kind words! 🙏🏻

Yes it was! Thanks!

Thanks!

Anytime! Thanks for watching!

I’ve used the standard capacity, couldn’t find other variants here. I plan to test in the future higher capacity ones.

Hi, you will need 3 screwdrivers or bits: pentalobe, philips and tri-wing. I recommend qi-ling brand, they’re good and not that expensive. You will need isopropyl alcohol, preferably 99%. Something to heat up the sides of the display, around 100 degrees Celsius. A suction cup. Tweezers, some prying tools like in the video. You can find these on aliexpress for example or depending on where you live, you should be able to find phone parts online stores. They have equipment as well.

@@TheRestoreGeek wow, thanks so much for the info

You’re welcome! Good luck with repairs 🫶🏻

True, but it’s still one of the best phones Apple made. And there are still people out there that can’t afford a newer phone. Even if you use it just as a phone or for browsing it’s still great 😊

I honestly haven’t tried higher capacity batteries yet, I can’t find any on my trusted suppliers stores, but I might experiment in the future. They should be fine as long as they fit the phone, but there’s always the possibility those numbers are lies, and they are actually less than claimed. Anyway, if they fit the phone I see no issue even if they are larger in capacity.

What amperage charger were you using? The stock Apple charger, or did you substitute a higher amps unit because you were too impatient that the larger amp-hour battery took too long to charge? "Bulging" is a sign of either an old battery or excessively large charge current. OR, it could simply be a defective replacement battery.

@@demef758 The battery has the same voltage and temperament, it just has a little more milli amps of storage and lasts longer in use. The same charger works just fine. Even my old battery never bulged tooo much, but was fully dead and I replaced. The new battery of course, didn't bulge.

​@@TheRestoreGeek As a former high tech designer myself, I was also suspicious of capacities listed as higher than the stock iPhone battery. However, it occurred to me that the energy DENSITY of batteries has increased significantly over time. But high much higher have capacities risen and over how long of a time span? I searched for "energy density increases of lithium-ion batteries over time," and got a number of hits. Sony was the first company to use these cells starting in 1991. According to the papers I found, they indicate that ending between 2022 and 2023 (when these papers were published), densities have increased between 3-4x. The iPhone 6s was introduced in 2016, so as of this writing (2024), battery technology has had 8 years to advance. Looking at a couple of graphs, you see an approximate increase in densities over this time frame (2016 - 2024) of between 2x - 3x. With that in mind, it is reasonable to think that a replacement battery for an iPhone 6s could contain higher energies, between 6.55 W-hr x2 or x3. Dividing watt-hours by 3.8, the nominal voltage of these batteries, that's from 1.72 A-hr (stock 6s battery) up to 3.44 - 5.17 A-hr today. I have seen some batteries advertised at 9 A-hr, which i think is marketing BS. But a newer battery with a capacity between, say, 3.5-5.0 A-hr is within the range of believability. I just bought and installed a battery rated at 3.2 A-hr, and it looks like my 6s is reading it as such. [For the uninitiated: "density" refers to the size of a battery divided by either its volume (such as cubic centimeters) or its weight (such as ounces). In the case of an iPhone, you have a fixed size (LxWxH) to drop a new replacement battery in. If the energy density of Lithium-ion batteries has increased over time, it means that you should be able find batteries today with watt-hour capacities that higher than battery the iPhone 6s was shipped with in 2016. Conclusion: a battery being advertised in 2024 as having 2-3x higher capacity than the battery that Apple shipped in 2016 is probably the real deal.]

Great research, thanks! And I agree completely, it’s just hard to order something and know for sure it was built recently, and not some printed numbers and bs. If you found a brand that’s reliable let me know. I have a few local sites from where I get replacement parts, and they’re good. But they only bring normal capacity batteries.

On iPhones, any normal use problems you get, is because of the battery. And yes the owner is happy, because the phone used to overheat like crazy. If your phone overheats, slows down, drops battery % suddenly, it's the battery, even if the % is still in the norm. 6S batteries are cheap, and if you still use the phone and think it's worth it, go for a replacement, you'll see a difference instantly. 😁

@@TheRestoreGeek Thanks!

@@slayni Anytime, good luck!

You either have to file it carefully with something so you can unscrew it with a flathead screwdriver, or you will have to drill the screw. Maybe there are other methods, but if nothing works, that's what I do.

It's running 15.7

@@TheRestoreGeek how did you made your home screen like iPhone 15

I didn't do anything it just defaulted like that...no idea

@@TheRestoreGeek Hmmm I don't have that but never mind that's ok thanks for helping 👍

Before I changed the battery I reset it to factory default...maybe it applied the latest theme

About 12$

What do you mean? You got just the touchscreen? 😮
