Frequently asked questions
Why does my battery drain after an update?
The phone optimizes apps and indexes files for a day or two after a big update. If drain continues after that, check Battery usage for a misbehaving app.
How do I check battery health on Android?
On Samsung, use Samsung Members › Support › Phone diagnostics › Battery status. On Pixel 8a and later, Settings › Battery › Battery health.
