The Pixel 9 Pro Fold has two batteries one in each half of the device. If your foldable phone is draining fast, shutting down early, or showing uneven battery percentages, the secondary battery might be failing.

We carefully open the foldable display assembly, replace the faulty battery, and seal everything back properly. This is a delicate repair that requires expertise, and we have it. Bring your Pixel 9 Pro Fold to our Santa Rosa shop, and we will get your battery life back on track.
