Follow this guide to remove or replace the battery in your Google Pixel 8a.
Lithium-ion batteries have a limited lifespan. If your phone doesn't hold a charge or dies unexpectedly, it might be time to replace the battery.
If your battery is swollen, take appropriate precautions.
You'll need replacement battery, back cover, and flash unit adhesives to complete this repair.
Note: Any repair can compromise the water resistance of your phone. Retaining water resistance after the repair will depend on how well you reapply the back cover adhesive.
