iPhone 6S Battery Replacement Guide (How To) - ScandiTech

Tutorial / Walk-Through: Replace your iPhone 6S battery in 20 minutes, a DIY video by Scandi Tech!

NOTE:
In this video we show how to replace an iPhone 6S battery by removing the front assembly completely. This is not necessary but most first time technicians find it easier to work with both hands free. If you proceed by *not* removing the front assembly, it needs to be held securely at a 90 degree angle or the cables can get damaged or tear. This results in loss of LCD, touch or front camera functionality.

We urge everyone to also read our text/image instructions before attempting the battery replacement as it can get tricky and if not done correctly, there is a risk of damaging various components.

We made this video to show everyone that it doesn't take an Apple-genius or a highly trained technician to remove and replace an iPhone 6S battery - anyone can do it!

A battery in an iPhone 6S, or any smartphone for that matter, works like any other battery - it wears out with time. After about 300 cycles, i.e. 300 full charges and discharges, a significant drop in performance is noticeable. The older and more used the battery gets, the more obvious is the performance drop. In the end the phone can end up shutting down when the battery percentage drops below 10-20%. In this case a fresh, new battery brings the phone back to life.

In some cases the battery swells. This results in the glass/digitizer lifting from its frame. If the battery is very swollen, it's not uncommon that a gap is apparent between the glass and the metal back assembly. This problem can also be fixed by replacing the battery.

Product info:
The iPhone 6S battery replacement kit linked in the description is a complete kit with battery, tools and instructions - everything you need to get the battery replacement done!
Our batteries are manually tested before they leaves our quality control center and they are packaged in a ESD safe bag before placed between two layers of protective foam. The tools are carefully chosen to make the battery replacement process as easy and smooth as possible. We've also chosen to include metal tweezers as it's a very handy tool and can be used both to open the phone as well as picking up screws and other small parts inside the phone.

*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

Although a very detailed and comprehensive video, I would suggest that there is no need to remove the screen and risk breaking other connectors. I used an old book end (or anything similar will work) and put an elastic band around it and the LCD to keep the LCD up at 90 degrees while working on battery. This also prevents possible error of connecting battery in wrong sequence with screen and shorting your screen, which it seems many people have done.. Just changed battery in my son's 6s a few minutes ago for first time ever and took me less than 10 mins without having to remove the LCD screen.

Yes yes yes it’s done followed tutorial no problem but if your a heavy handed person don’t just don’t and mans voice is pleasant to listen to

Excellent guide. Pulling the adhesive strips didn't really work for me, I just had to keep applying heat and work the battery up a little at a time. Thanks guys, very good! 10/10.

Thanks it was really well explained, I succeeded ! I liked the zoom when you remove the display, other vids don't show that as clearly. I only had a bit of trouble when replacing the battery as the connector wasn't "bent" like the original one, i had to bend it a bit. And also when replacing the display, i found it easier to bring the display towards me (like 70 degrees angle) to put the metal plate back, at a 90 degrees angle it was too hard.

Manufacturers don't recommend heating the back of the phone, the tape wlll come out cleanly if you just pull straight out toward the home button and up at a less than 60º angle to the phone. Prying can damage the battery and potentially cause a fire -- see "t-pain" below!

Blessings!

Thanks for the nice professional demo. My screen was impossible (nearly impossible) to open. The 6s was released in September of 2015 and in April 2020 we are getting close to 5 years old, and when I finally, carefully, frustratingly got it open, it had a stock, untouched, original Apple battery. The pull tabs for the adhesive strips were NOT folded towards the bottom for easy access, they were wrapped up over the battery towards the top of the phone, and the black "end" of the white tabs covered and hid the adhesive tabs really well - I didn't recognize them at first. Unlike in your video, one I had uncovered the white strips I just pulled them straight out and though they got really really long didn't snap and break on me. From there replacement was a breeze. I used the "book end" method described by Lucarvian in the comments to keep the screen from exceeding the 90 degree limit. I note that some other installers who remove the screen cables advise NOT pushing on the connectors at the middle, only from one end then the other end otherwise the screens have problems (in your video you did have problems but removing and replacing fixed them). Positioning the battery is a little tricky. The replacement adhesive strips are really grippy and don't allow repositioning. So I tried connecting the battery using the adhesive strips just to know where in the slightly oversized battery slot the battery should be replaced. Unfortunately I didn't position the adhesive strips correctly - I put them in upside down. When installed correctly, the removal tabs should be accessible on top (hence, wrapped around the bottom of the battery and barely extending over the front edge) for future replacements. Guess any future battery replacement will have to be "brute force".

Thank you for the thorough and clear instructions! I would have liked a little explanation on what to aim for in the heat range for the adhesive, and some mention of the gasket would have been nice. However, I was able to successfully replace my battery, fairly easily thanks to this video.

great video it made removing and installing a new battery easier

[Shakabrassiere]

Thank you so much!! Successfully saved myself $50 by replacing with this kit rather than having Apple do it.

[claudeperrault]

Thank you for such a great video! I have replaced successfully my battery thanks to your excellent explanations.

[ayan]

Thank you so much this helped a lot. My phone is fixed thanks to you.

[richardstarzak]

Thank you. Worked a treat. I lost a screw even though I had a magnetic mat. I'd recommend keeping the screws in order, and well away from the work surface.

[AbnerChamate]

I got lucky battery was heating after trying to remove it. I guess is better with battery dead or no charge. Thanks for video

[maconcc]

Thank you for the wonderful video! I have replaced my battery and charger port, but why my water damaged iPhone 6 still not working? Do you have any suggestions? Thank you!

[josephinewalker]

Thanks for the video changed my battery exactly how you did it for 20 from amazon and they gave me 2 batteries

[raychilders]

I watched several videos - if I could only watch one, this would be it. Definitely disconnect and remove the top half ( with screen) of the phone before removing battery as quite a bit of handling of the bottom half can be needed to get the battery out.

[galenztwo]

Bro this is by far the best video, excellent.

[LoboBrand]

so uh i just did this repair and i was putting the screen back like the cables and i tried to see if the phone would work and it booted up and then all the sudden the screen went black i could still see the apple logo but it had big black bars going through anyone know if i messed it up permanently or should i just keep trying to disconnect the cables and reconnect them

[alfindigo]

Is there any reason you don’t remove the Taptic Engine? It would enable you to pull the adhesive strips straight out if you did
