Use this guide to replace the battery in your Google Pixel 8.
If your battery is swollen, take appropriate precautions.
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.
You'll need replacement screen adhesive to complete this repair.
Note: This guide was made with the 5G mmWave antenna model of the Pixel 8. If you have the non-mmWave version, you can still use this guide—just skip the steps that mention the 5G mmWave antenna.
