Introduction
Follow this guide to remove and replace a worn battery for the Pixel 3. If your battery is swollen, take appropriate precautions.
For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
What you need
-
-
Heat an iOpener and apply it to the bottom of the phone for one minute.

Lift on the suction cup with strong, steady force to create a gap.
-
Insert an opening pick into the gap.
-
-
-
Slice the adhesive along the bottom edge of the phone and around the right corner.
-
Leave a pick in the bottom edge to prevent the adhesive from re-sealing.
-
-
