Stuck partial wake locks

Partial wake locks are a mechanism in the PowerManager API that lets
developers keep the CPU running after a device's display turns off. A partial
wake lock becomes stuck if it is held for a long time while your app is
running in the background (no part of your app is visible to the user).
Detect the problem
Android vitals
Android vitals can help improve your app's performance by alerting you in the
Play Console when your app exhibits stuck partial wake locks. Android
vitals reports a partial wake lock as stuck when it lasts at least one hour in
the background within a 24-hour period.
The number of battery sessions displayed is an aggregate for all measured users
of the app. For information on how Google Play collects Android vitals data, see
the Play Console documentation.
