I watched 4 tutorials over this to prepare, this is without a doubt the best one. Everything was perfectly shown and described in immaculate detail, you weren't trying to get viewers in and out within 5 minutes. Paused and followed along with it and successfully installed a new battery in my girlfriend's iPhone 6s. Fantastic work, dude! 🙏

I would definitely state that this is one of the best instructional video on youtube and definitely so for the purpose stated. Though mine is 6S, not 6s Plus, it still guided me through so smoothly that after realizing in the middle of it that mine is different and thus has minor differences in internal brackets screws positions as well as two glue strips vs three on 6s Plus, I still proceeded to the end because the video is extremely thorough and detailed as to how to do it right and also avoid certain problems in advance as the entire process is one shot deal and no corrections possible. I especially liked the fact that the author tested the new battery with the phone PRIOR he buttons up everything together. Very professional job! Thank you, my friend!

Brilliant video. Perfect for replacing the iPhone 6S Plus battery with genuine Apple parts. Don't bother to watch any of other tutorials.., this is the best by a country mile!

This is one of the best instructional videos that I found on this subject. Unlike the Ifixit videos which tell you to just "reverse the steps" to get the phone back together, this one walks you through all the steps from start to finish including replacing the seal and testing the screen connections before finally closing up. One point that would be helpful is to tell the viewer to run the battery down to less than 25% before proceeding. This helps avoid the problem of gaseous emissions or fire in case the battery is pierced. This problem is mentioned in the chats on some of the other videos.

Fantastic tutorial, many thanks. Tiniest screws I have ever had to deal with but patience is the key. I took over an hour but hopefully works better now. Thanks again!

This tutorial is a godsend, I was so tired of

I successfully changed battery after watching this tutorial. No other video I watched mentioned the blow dryer helping remove glue part, I'm glad I found this tutorial. Thanks a lot for putting into the work.

Just replaced my second battery in the 6S. This is by far the best video to watch to do the job.

A tip for releasing the battery: When you pull on the tab, apply some tension and then wait a few seconds until the tension is released as the glue strip releases. When it does then pull just a few centimetres and wait again until the tension is released. If you just keep on pulling without waiting for it to release, the glue strip breaks.

Thank you so much for doing this video. I was able to successfully replace my battery in 45 minutes by following your instructions. I think the hair dryer to heat the iphone made a big difference in getting the case open and to help in removing the battery.

This video was the best!! Hardest part was removing the old gasket, very sticky. Took me over an hour but this old lady is happy!! Thanks.....

How I missed the good old days when you can just pop open the back cover and slide in a new battery like those old Samsungs. Anyway, this tutorial helped out greatly! Thanks a bunch!

I walked through the video right with the commentator to replace my battery. With the exception of my kit not coming with a replacement gasket, it worked exactly as he described. Great video! Thank you for the tutorial!

Awesome tutorial I was able to change my own battery no problems thank you

Thanks for the detailed helpful instructions. I used my wife's hair dryer multiple times to soften the adhesive, and it allowed me to remove the screen and battery without a hitch. I put in a 2750mAh battery (1.6X the original 1715mAh). The new battery charged to 100% quickly and lost only 6% overnight (14 hours). The original 6S battery would go from 100% to 20% in 1/2 hour. Due to my fading eyesight (I'm 79), my biggest challenge was removing and reinstalling the many tiny (really tiny) screws. An added caution is to place the replacement battery nearest to the bottom edge so that the wiring to the battery is snug and fits alongside it. My replacement battery came with all the needed tools, the screen gasket, and two battery adhesive strips.

This is, by far, the most detailed, thorough and helpful video for replacing the battery in an iPhone 6s that I could find. Thanks for making it possible for me to change my own battery!

Excellent tutorial. One of very few that show the ESSENTIAL heating up of screen and battery prior to their removals, correct use of plastic tools (rather than metal which may cause inadvertent damage). Good use of a weighted block and band to hold the screen at right angles prior to screen removal. Also one of few videos showing how to attach a new screen gasket. My only additional tip is to fix double sided tape, or loops of sellotape, to paper to (a) stop losing screws and (b) most importantly ensure each screw goes back in the right place!

I would like to say thank you for this video.A friend of mine wanted to change out his iphone 6s battery, and because of this tutorial i was able to replace it for him relatively easy. I'm an electrical single major at my university, but i was unfamiliar with apple technology. it was a successful swap, and I learned quite a bit during the process; if you don't have the hot air gun the screen can still be removed, you just have to be a bit more carefull and patient with the suction cup. thanks again for making this video, its really helpful and to the point.

Thanks man, followed your guide and it all went smoothly! Even 4 years later your guide is still so relevant, thanks again man!

Really appreciate the step by step. I've seen others blow through the instructions in a few minutes and I often hacve to pause or rewind, and still couldn't see what they're doing. This is the best tutorial for battery replacement. Thank you

Easy, peasy....Nice video....Thank you!

Glad i saw this video... My battery replacement kit didn't come with a gasket. Thanks very much

Best and most detailed of all the iPhone battery replacement tutorials. This covers the replacement of the glue strips surrounding the edges of the screen as well, essential to keeping out liquids.

Thank you so much for the time and effort you used to make your great video. I used all 10 of my thumbs, only lost one of the tiniest screws. Success, my 6s still works more than one day now without recharging. Your step by step made it possible.

Thank you so much! I didn't think I could do it. I followed your tutorial step by step its awesome, your the best. Thank you once again.

It worked!! Excellent video, very detailed...Thank you!! My kit had a battery prybar, so no credit card needed when the tabs break off.

Very clear detailed tutorial and easy to follow. My wife and I still own iPhone 6s, both phones and batteries are working well. I watched the whole tutorial and saved it for future use. Luckily, I already have all the tools in the kit ( Tekton ) that I ordered from Amazon a few years ago. I had issues with the battery not holding charge about a month ago. I almost brought it to Apple store to have the battery changed but the problem was resolved after I did the software update. I will surely use your tutorial when the comes to change the battery. Thanks for sharing.

THANK YOU A MILLION TRILLION TIMES for this! I changed the battery in my iPhone 6s today. This is the BEST, MOST COMPLETE instructional video ever! XOXOXOXOXOXOXOXO!!!!!!!!!!!!!!!!!!!!!

new subscriber here, just bought my ip6s+ today😁

Brilliant video, just swapped my battery over and it was so easy having watched this video, excellent job, thank you

I NEVER leave comments but wanted to thank you. Your step by step instructions were soooo easy to follow! My left tape broke but with a little patients I got it. THANKS A BUNCH!!!!

thankyou, I replace my battery today following your guide on this video. it was very helpful for me, thx. if anyone is attempting this repair, please be careful when disconnecting and reconnecting the lcd flex cables (3 cables). during my first attempt of reconnecting flex cables, and plugging in my battery, my phone turns on, but the display is off, but the touch id is working (vibrating as if I need to insert password before using touch id after booting phone). I turn off my phone, reconnect the flex cables making sure they connect well on the both side, I push left and right until they're okay. and the display finally turns on. battery adhesive tabs are important, because if you use doubletape, you will have a hardtime to remove the battery on future replacement. (my last battery replacement was done by technician and they put double tape instead of glue tabs, I had a hardtime getting the battery out).

Thank you so much. Now my phone's lifespan is expanded!

Best tutorial on KZfaq... Well done ol lad.

Hands down, this is the best tutorial I have seen. I took my time, used plenty of heat and reheated for each of the battery adhesive strips. PULL SLOWLY. All came out perfectly. The new case gasket was the most touchy. I used the I Fix It complete kit. The battery adhesive strip were already attached on the battery. Thanks again. Now I get to do my wife's phone.

I am so happy that one of the glue tabs broke on you because the same thing happened to me. I was able to remove the broken tab following your instructions. That was the most frustrating part of replacing the battery. Thank you so much for such a detailed instructional video!

Perfect thank you very much!!

thank you, its helped me

Your attention to description and technique won you my subscription. Great Job

What a thorough video on battery replacement. . You get an A+.

thank you so much, the heat actually weakens the pull tabs, which is why two of those broke

Thank you for the video! However after powering it back up I have found that the phone speaker and cameras won’t work anymore. Any tips or suggestions?

I have watched several tutorials and this is by far the best. I was able to replace my battery within a few minutes. Thank you very much.

Clear and thorough tutorial. Thank you. Enabled non tech person to change battery and have iphone start up without problems.

I wouldn’t use tweezers to unplug the connectors specially the battery because you could short circuit something inside the phone

I had a mishap that cause all the screws to fall out of my magnetic tray and now I don't know one from the other. Whaaaa! Whaaaa! Edit: Noticed 2 of the screws have a blue mark on them.

Thank you very VERY MUCH !!! So nice to see step by step how to do this. I just finished the job and my phone battery health is back to 100%. Hopefully I can use the phone now for a few more years. At least for now I reduced my part of the throwaway society by only replacing the battery. Goof luck with your videos. Greetings from the Netherlands.

The tutorial is great. I successfully changed my iphone 6s phone battery. Got both tapes broken so had to do the nasty step with the card, slightly bending the battery and worked perfectly well. It took mi about a bit more than an hour, as cleaning the original gasket was tricky, it was very sticky so I had to pay extra attention to it. At the end the phone works perfectly and the new battery works fine as well. Great tutorial, big thumbs up!

I would use plastic tweezers instead of metal. Also, I would heat the phone for each of the three battery glue strips. Otherwise, great video. The explanation of steps and care for delicate parts of the phone is great.

北京一卡通好评！ Good job Beijing metro card!

The best tutorial for battery replacement.

Thank you so much. I used this for help with my iPhone 7 battery replacement (in conjunction with an iPhone 7 video), because the iPhone 7 videos I could find all didn't show the reapplying of the adhesive strips or adhesive gasket. The concept was exactly the same as you showed in this video, so it was extremely helpful. Thanks again.

Not supposed to open the phone more than 90 Degrees because of the cables attached to the Digitizer on the top - - DO Not ATTEMPT To Open FLAT !!

thank you fir this. i came for the part where you put the battery adhesive on because the other guide i watched used a different kind. ended up watching until the end. cheers

Adhesive installation strips installation is exactly what I was looking for. Thanks

Thank you. You have removed the “mystery “ of replacing an I Phone battery!

Thank you, your tutorial is best on KZfaq. Usually they don't describe all the details like you did. I have just repaired my iPhone.

Very detail. Helped me to replace the battery within 10 mins.

This was an excellent tutorial and left nothing to guesswork. I successfully replaced the battery in my iphone6s+. Thanks for the clear video pics and thorough instructions.

Just finished replacing my battery and gasket this step by step instruction video was very helpful as I also had broken tape and had no problem fixing this with your help thanks again .

This was definitely the best tutorial out there. I also tried to replace my screen but the new screen didn't work when I went to restore and retrieve data. So I had to repeat the battery install a few times, losing the seal in the process. But the phone at least holds a charge, even if not a whole day.

Great Tutorial ever! No prior knowledge about it but watching this video made me feel like I have done it before. Thank you for this video.

Well done! Thank you so much! This was my first ever attempt at servicing any iPhone, in any way. Everything works perfectly.

Very helpful. I just replaced the battery on my iPhone 6S Plus with the iFixit kit.

You did an excellent job of explaining how to replace the battery on the iPhone 6S. I'm glad the adhesive snapped on this video because it did the same as I was trying to remove the battery. Had you not shown us how to manipulate that issue, I would have been lost. I was able to use a credit card and lift the battery and then use tweezers to grab hold of the middle strip which broke and then gradually pull it out. Thanks so much!

Thank you. Watched several other videos. This one is the most comprehensive one. Excellent video.

Thanks for making what seems like a complicated process look easy. I am going to try it.

Very good. Very easy to follow. Glad that everything did not work smoothly because it's good to see how to handle problems like breaking tabs for the battery. Appreciate the tips on the screws as well and the heating of the case. Have not tried it yet but feel much more confident having viewed this video.

this is the best tutorial i have seen very very well don thank you very much GREAT JOB LOOKING FORWARD TO SEE OTHERS BY YOU

thank you so so much for this, very much appreciated Ifixit's tutorials were a bit vague for a first timer, yours was great and thorough.

Great thanks. You made the job so easy. The hairdryer is a great tip.

Thanks for this. It helped me position the glue strips. A good tip to hold the screen vertical while working on the battery compartment. I have a 6, but this was helped me a lot. Great video!!!

Thanks for the info. I bought almost the exact same kit from Amazon and was able to follow almost all the steps. Thanks for sharing!

Bravo. Hands down the best video for battery replacement. No stone unturned!

Best tutorial I've seen hands down. Thanks for the help! Battery is now replaced and phone functions great!

EXCELLENT by far the best video for this application. Well done.

This tutorial is very well done. I was able to swap out the battery on my mom's iPhone 6S Plus with it and it works like new. Thank you so much sir.

Thanks for this video! Soo much better and detailed than many other videos! Awesome!!

Very detailed video guiding through the process! Love it and easy to follow ❤

Great video.. You are very careful, detailed helpful information to prevent damage to device from a novice like myself. Thank you :)

Amazingly well presented .The job involved into making a devise we are so fond of and is so useful to our daily activities. Thank you so much for this eye opener . Jose from Melbourne Australia.🏆

Glad I found your tutorial definitely could not open the phone without the heat. Thank you.

So many thank’s for guide “detailed step by step replacement battery” iphone

Thanks very much was very helpful, just the last bit i mucked up the Battery adhesive but the job was done anyway. Thank you

Best battery change video I've seen so far. Clear camera work, precise direction and tips. You would be a great surgeon! Thanks for posting. Will be doing battery change on iphone se soon.

Thanks for this GREAT TUTORIAL. My phone works great.

I approached this battery change with trepidation but your superb step by step tutorial made it relatively simple.One tip for those wanting to attempt this.The screws are extremely small and easily lost.

Excellent tutorial, I followed and everything is perfect . The new battery is installed now Thank you.

I just read the comment before mine. And the are 100% on the money. Your the BEST

Superb explanation/demonstration, thank you kind sir!

Wow! Great explanation! iPhone 6s is not easy to change the battery, but these instructions got me through it! Thanks!

Excellent, well done. Love it? Step by step. Perfect,anybody can follow and do a good job with their phone.👏🏻👍

Watched your video, bought parts I’m about to give it a try, good instructional vid, good photography thanks. I have a newer iPhone but I love my 6+ because it was the last one with a hardware headphone jack, when I DJ I can use this phone as a back up deck, it’s my favorite iPhone, I like it more than the new ones so I plan on keeping it alive forever as a back up for podcasting, for photography, recording music etc. etc. etc., 6+ was the best iPhone ever.

This was a great tutorial, thank you for taking the time to put it together.

Excellent video, very good explanation of what to do. My phone works perfectly now. Thank you x

A yery good and thoroughly explained tutorial. Thank you very much! I just have two things I want to add, which some people might find useful: 1.) The order for the screws on the battery connector plate are simple: The longer one goes into the left hole, the smaller one into the right hole. The other way is not possible because the short screw is in fact too short to be tightened into the left hole. I was hesitant beforehand to put the screws back in because I forgot the remember the order. 2.) I know you stressed the importance of putting the display assembly cables back in correctly, but I want to add that doing this can be really tricky. At first I thought I did everything correctly, but afterwards only half of my backlight was working and I feared that I fried parts on the motherboard. I repeated the process veeeeryyyy carefully and to my relief the backlight was working again. So don't panic if the same happens to you - just try it again with a little more care.

This video saved the day for me! I was getting ready to throw the whole thing in the trash until I saw the hairdryer trick. Immense thanks! Best video out there for battery replacement. Two bad there aren't three thumbs up....

OUTSTANDING tutorial! Everything was you described!

Great video...you stayed calm when it didn't go right

This instruction is also well fit for the repair kit I got from iFixIt. I managed to have my iPhone's battery replaced. Thank you.
