Use this guide to bring life back to your iPhone 6s Plus with a new battery. If your battery is swollen, take appropriate precautions.
This guide instructs you to detach the front panel assembly; this is intended to prevent damage to the display cables. If you feel comfortable supporting the display carefully while peeling the battery out of the iPhone, you can skip the display removal and go directly to the battery removal steps.
This guide also instructs you to remove the Taptic Engine. This procedure is optional but recommended to assist removing the battery's adhesive.
For optimal performance, after completing this guide, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least two more hours. Then use your iPhone until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.
You can also use this guide to replace the battery connector bracket.

Most common on IPhone 6s/6 repair jobs is this battery replacement. Great tutorial!
so few comments on this one?!
has any/many done this without the adhesive strips.. and was it ok?
If you mean the battery adhesive strips, sure—you can put a piece of double-sided tape down the back of the battery, and it probably won't move anywhere. There's not much room for the battery to move anyway. Use the adhesive strips if you want to do it right—but, if you're in a bind and you just need the phone working, you can skip the strips. And you can always open the phone back up and add the adhesive strips later.
If you mean the adhesive gasket around the display, the answer is pretty much the same—It's better to have it, but it doesn't hurt anything to put the phone back together without it.
by far the easiest repair I've done. only 3 screws! really dont think the cables need to be disconneted. i just used a shoe lace to gently hold up the screen. sticky strips came out fine. happy. thanks.
Where can one buy the adhesive gasket for the case
