Introduction
Use this guide to replace a dead or low battery.
If your battery is swollen, take appropriate precautions.
What you need
-
-
If possible, drain the battery before disassembly. When the battery is charged, there's an increased risk of a dangerous thermal event if the battery is overheated or damaged during repairs.
-
Prepare an iOpener and heat the back of the phone along its bottom edge for about two minutes, or until it's slightly too hot to touch. This will help soften the adhesive securing the rear glass.
-
-
-
Apply a suction cup to the bottom edge of the rear glass.
-
Pull up on the suction cup with firm, constant pressure to create a slight gap between the rear glass and the frame.
-
If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools quickly, so you may need to heat it repeatedly.
-
Insert an opening pick into the gap you created under the rear glass.
-
-
-
Slide the pick all along the bottom edge of the phone to slice through the adhesive securing the rear glass.
-
-
-
-
Slide the pick all along the top edge of the phone to slice through the adhesive securing the rear glass.
-
-
-
Use a pair of tweezers to carefully peel up the black tape covering the battery.
-
Remove the tape.
-
-
-
Use a Phillips driver to remove seventeen screws securing the plastic cover:
-
Eleven grey 3 mm-long screws
-
Five black 2.5 mm-long screws
-
One silver 3.5 mm-long screw
-
-
-
Insert the pointed end of a spudger into the notch at the top left edge of the plastic cover.
-
Pry up with the spudger to lift the upper edge of the cover and release the clips holding the cover down.
-
Remove the plastic cover.
-
-
-
Use the pointed end of a spudger to pry up the battery connector and disconnect it.
-
-
-
Prepare an iOpener and apply it to the right half of the screen for at least two minutes, in order to soften the battery adhesive underneath. Reheat and reapply the iOpener as needed.
-
-
-
Use an opening pick to steadily pry the battery up, starting from the outer edge of the battery.
-
Remove the battery.
