Overview
- Google activated the warnings on March 1, 2026, with a phased rollout to more apps over the coming weeks.
- Apps are flagged if they log at least two hours of background wake locks in more than 5% of user sessions over the previous 28 days.
- Offending titles may receive a badge on their Play Store page and can be removed from recommendation surfaces to reduce visibility.
- Legitimate background uses such as audio playback and turn-by-turn navigation are exempt from the warning policy.
- The metric is part of Core Vitals, and Google urges developers to use tools like WorkManager, citing early fixes and a Whoop case study that cut wake-lock impact by over 90%.
