Google introduces an 'excessive partial wake locks' metric aimed at flagging apps that unnecessarily drain battery life through prolonged CPU usage in the background.
Metric Implementation Details
The new metric identifies apps holding more than two cumulative hours of non-exempt wake locks within a 24-hour period. If this behavior occurs in 5% of user sessions over 28 days, the app is flagged for poor battery behavior. Beginning 2026-03-01, such apps may have reduced visibility on Google Play, accompanied by a warning label: “This app may use more battery than expected due to high background activity.”
Collaborative Development and Impact
Developed in collaboration with Samsung, the metric uses real-world device data to help users and developers. It encourages optimal battery usage by promoting apps that minimize unnecessary background activity. The aim is to enhance user experience and device longevity by reducing undue CPU strain.
Steps for Users
Users can manage this by adjusting app permissions, restricting background activity, or opting for less power-intensive alternatives. These steps can preemptively address battery consumption issues flagged by the new metric.
