Google has introduced a new system-level metric called “excessive partial wake locks” to identify apps that prevent Android phones from entering sleep mode, which leads to unnecessary battery drain. This metric, co-developed with Samsung, will be integrated into Android's core vitals metrics to help measure app performance and efficiency. Starting March 1, 2026, apps that keep devices awake for more than two hours unnecessarily will face penalties, including reduced visibility in Play Store recommendations and potential user warnings. This initiative aims to improve transparency for users and encourage developers to optimize their apps.
