Google is taking significant steps to enhance user experience on Android devices by implementing a new metric aimed at curbing excessive battery drain caused by certain applications. This initiative, detailed in the Android Developers Blog, introduces the “excessive partial wake locks” metric, which has recently transitioned from beta to general availability.
Understanding the New Metric
- The metric identifies user sessions as excessive if an app maintains non-exempt wake locks for over two cumulative hours within a 24-hour period.
- Should an app exceed the “bad behavior threshold,” defined as having 5% or more of its user sessions categorized as excessive over the past 28 days, it will face penalties starting March 1, 2026.

This move is pivotal as apps that fall short of the new standards may find themselves excluded from prominent discovery surfaces, such as recommendations within the Google Play Store. Additionally, users may encounter a red warning label on the app’s listing, indicating that “This app may use more battery than expected due to high background activity.”
- The metric was co-developed with Samsung, combining insights from both Google’s Android platform and Samsung’s real-world device and battery data.
- Developers can now access this new metric through the Android Vitals console, allowing them ample time to make necessary adjustments before the enforcement date in March 2026.
The Importance of Wake Locks
For those unfamiliar, a wake lock is a feature in Android devices that permits applications to keep the phone awake by accessing the screen, CPU, or both, even when not in active use. While certain applications, like music players, require this functionality to operate effectively in the background, poorly designed apps may misuse wake locks, leading to significant battery drain.
- Battery drain is a prevalent concern among Android users, and this update to core metrics and Play Store policies aims to tackle the issue from the developer’s perspective while still allowing consumers to employ additional battery-saving strategies.
- As a result, users can expect to see warnings on Play Store listings for apps that consume more battery than necessary. Over time, this new metric is anticipated to discourage poor app behavior, ultimately contributing to improved battery life across Android smartphones.
Looking Ahead
This initiative is particularly beneficial for users with older or lower-performance Android devices. Google plans to enforce the new Play Store policy starting in March 2026, providing developers with sufficient time to optimize their applications while promoting best practices in app development.
- In the future, we may anticipate the introduction of more detailed Android Vitals metrics aimed at further reducing the prevalence of low-quality apps on the Play Store.
