Overview
- The excessive partial wake locks metric has moved out of beta and is now a permanent Core/Android Vitals measure available to all developers.
- A user session is classified as excessive when it records more than two cumulative hours of non‑exempt partial wake locks within a 24‑hour period.
- An app crosses the unacceptable behavior threshold if at least 5% of its sessions over the past 28 days are excessive, which triggers notifications in Android Vitals.
- Beginning March 1, 2026, affected apps may receive prominent battery‑use warnings on their Play Store pages and can be demoted or excluded from recommendation areas.
- Google developed the metric with Samsung and is expanding Android Vitals analysis tools, while exempting system‑held wake locks that deliver clear user benefits.
