Use this guide to bring life back to your iPhone 6s 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.
For optimal performance, calibrate your newly installed battery by first draining it below 10%, then charging it uninterrupted to 100%.
You can also use this guide to replace the battery connector bracket.
- Power off your iPhone before beginning disassembly.
- Remove the two 3.4 mm P2 Pentalobe screws on the bottom edge of the iPhone, next to the Lightning connector.
- Apply a suction cup to the lower left corner of the display assembly.
- Take care not to place the suction cup over the home button.
- Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
- Place the flat edge of a spudger into the gap between the screen and rear case, directly above the headphone jack.
- Twist the spudger to widen the gap between the front panel assembly and the rest of the phone.
- Insert the flat end of the spudger on the left side of the phone, between the display assembly and rear case.
- Slide the spudger up the side of the phone to separate the adhesive and pop the clips free.
- Remove the spudger and reinsert it on the bottom edge, where you pried the phone open.
- Slide the spudger to the right, along the bottom edge of the phone.
- Slide the spudger up the right side to continue separating the adhesive and popping the display clips free from the iPhone.
- Use the suction cup to open the display, breaking the last of the adhesive.
- Pull up on the nub on the top side of the suction cup to remove it from the front panel.
- Gently grasp the display assembly and lift it up to open the phone, using the clips at the top of the front panel 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.
- Remove two Phillips screws securing the battery connector bracket, of the following lengths:
- One 2.9 mm screw
- One 2.2 mm screw
- Remove the battery connector bracket from the iPhone.
- Use the point of a spudger to disconnect the battery connector by prying it straight up from the logic board.
- Push the battery connector away from the logic board until it stays separated from its socket, so as to avoid any accidental connection to the battery while you work.
- Remove the following four Phillips screws securing the display cable bracket:
- Three 1.2 mm screws
- One 2.8 mm screw
- Remove the display cable bracket.
- Use a spudger or a clean fingernail to disconnect the front camera flex cable by prying it straight up from its socket on the logic board.
- Disconnect the digitizer cable by prying it straight up from its socket on the logic board.
- Disconnect the display cable by prying it straight up from its socket on the logic board.
- Remove the display assembly.
- Use tweezers to peel back the tips of the two adhesive strips along the bottom edge of the battery.
- Slowly pull one battery adhesive tab away from the battery, toward the bottom of the iPhone.
- Pull steadily, maintaining constant tension on the strip until it slips out from between the battery and the rear case. For best results, pull the strip at a 60º angle or less.
- Repeat for the second strip.
- If you removed both adhesive strips successfully, skip the next step.
- If you successfully removed both adhesive strips, move on to the next step. Otherwise, you will need to pry the battery from the rear case.
- Prepare an iOpener and apply it to the back of the rear case, directly over the battery. Alternatively, you can apply heat using a heat gun or hair dryer.
- After about a minute, flip the phone over and use a plastic card to break up any remaining adhesive behind the battery.
- Thread the floss or string behind the upper battery corners, bring the ends together, wrap them around a folded cloth, and pull evenly.
- Remove the battery.
To reassemble your device, follow the above steps in reverse order.

For optimal performance, calibrate your newly installed battery: Drain battery below 10%, then charge uninterrupted to 100%.
