Introduction
Use this guide to bring life back to your iPhone 6 Plus with a new battery. If your battery is swollen, take appropriate precautions.
This guide instructs you to remove 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.
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.

Video Overview
-
-
Power off your iPhone before beginning disassembly.
-
Remove the two 3.6 mm P2 Pentalobe screws next to the Lightning connector.
-
-
-
If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger phones like the iPhone 6 Plus.
-
Close the handle on the iSclack, opening the suction cup jaws.
-
Place the bottom of your iPhone in between the suction cups.
-
Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone.
-
-
-
If you don't have an iSclack, use a single suction cup to lift the front panel:
-
Press a suction cup onto the screen, just above the home button.
-
-
-
-
While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.
-
Using a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while continuing to pull up with the suction cup.
-
-
-
Pull the home button end of the front panel assembly away from the rear case, using the top of the phone as a hinge.
-
Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone.
-
Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.
-
-
-
-
Peel back the first battery adhesive tab from the bottom right edge of the battery.
-
-
-
Gently pull the battery adhesive tab away from the battery, toward the bottom of the iPhone.
-
To avoid tearing the adhesive strip, be careful not to pull against the battery or lower components.
-
-
Continue pulling, allowing the strip to slowly slip out from between the battery and the rear case. When you feel increased resistance from the strip, stop pulling and continue with the next step.
-
-
-
Peel back the second battery adhesive tab from the bottom left edge of the battery.
-
Again, gently pull the battery adhesive tab upward and away from the battery, allowing the adhesive strip to slowly slide out from between the battery and the rear case.
-
Continue pulling the adhesive tab until you feel increased resistance, and then stop.
-
-
-
When you feel increased resistance from the adhesive strip, pull it gently around the lower left corner of the battery.
-
Continue pulling the adhesive tab upward and away from the left edge of the battery, allowing it to slowly slide out from between the battery and the rear case, until the strip comes free from the iPhone.
-
-
-
Peel back the final battery adhesive tab from the bottom edge of the battery.
-
Gently pull the battery adhesive tab upward and away from the battery, allowing the adhesive strip to slowly slide out from between the battery and the rear case.
-
Continue pulling until the final strip comes free from the iPhone.
-
If you removed all three adhesive strips successfully, skip over the next two steps.
-
-
-
-
If any of the adhesive strips broke off and the battery remains stuck to the rear case, prepare an iOpener or use a hair dryer to heat the rear case directly behind the battery.
-
-
-
Flip the iPhone back over and insert a plastic card between the left side of the battery and the rear case.
-
Press the card in farther to break up the adhesive behind the battery.
-
Thread the floss or string underneath one end of the battery and pull side to side in a sawing motion to separate the adhesive.
-
