Use this guide to replace a dead or worn-out battery in your Google Pixel Watch 4.
Your watch's battery has a limited lifespan. If your watch doesn't hold a charge or dies unexpectedly, it might be time to replace the battery.
This guide was written using a 41 mm LTE model Pixel Watch 4. While some photos may contain slight visual discrepancies, procedures for all 41 mm and 45 mm models are functionally the same.
