The end of “hardware” apps: Google Play is launching a major crackdown on battery-killing apps.

Wake Locks: The Main Enemy of Your Autonomy

To understand the changes, it’s important to understand the technical concept that’s been the center of attention: “wake lock.” Wake locks are a mechanism that allows Android apps to prevent the device from entering hibernation (Doze mode) or turning off the screen. These locks are necessary for legitimate background processes, such as playing music, downloading large files, or syncing data.

However, it is “Partial Wake Locks” that are the root cause of the problem. They allow the screen to turn off, but prevent the central processing unit (CPU) from entering sleep mode. If the developer misuses this mechanism and doesn’t release the lock after finishing its work, the app continues to keep the CPU active, even though the smartphone appears inactive. This leads to hidden, but catastrophic, drain on Android’s battery.

New Thresholds: When an App Becomes “Bad”

Google, in collaboration with Samsung, developed clear thresholds for measuring excessive power consumption. This metric, called “Excessive Partial Wake Locks,” was added to the Android Vitals set of key quality metrics. This provides both users and developers with a clear understanding of what constitutes unacceptable behavior.

Clear criteria for smartphones

• Excessiveness Criteria: A user session is considered excessively discharged if the cumulative duration of non-exempt wake locks held exceeds 2 hours within a 24-hour period.

• Penalty Criteria: Google Play will begin to apply battery penalties if 5% of an app’s user sessions over the last 28 days exceed the specified 2-hour threshold.

Criteria for Wear OS watches

For watches with significantly smaller batteries, Google has long applied stricter standards. A Wear OS app is considered poor quality if it results in battery drain of more than 4.44% per hour during active use. This experience helped Google extrapolate the system to smartphones.

Real-world implications for developers and apps

The new Google Play policy isn’t just recommendations; it’s serious penalties that could have a direct financial impact on developers. All changes are aimed at encouraging high-quality Android battery optimization early in development.

Warning for users

• Warning Visibility: If an app exceeds the bad behavior threshold, users will see a direct warning on the app’s Google Play store page.

• Wording: The message will be something like, “This app may use more battery than expected due to high background activity.” This creates a negative reputation, encouraging users to seek out more energy-efficient alternatives.

Loss of visibility and search rankings

• Ranking Demotion: Apps labeled as “power-hungry” will be excluded from the “Promo” sections. This applies to prominent areas such as Google Play recommendations and collections, which are a critical source of new downloads.

• Loss of traffic: A decrease in ranking and visibility will lead to a direct decrease in downloads and revenue, which is a powerful incentive for developers to fix problems.

Google’s proactive actions

Google is giving developers time to correct the situation. They will receive warnings and detailed information about wake lock abuse via the Android Vitals panel in the Play Console well before the Google Play penalties are implemented. This underscores Google’s desire not to punish, but rather to ensure the overall quality of the ecosystem.

What can a user do to save battery on Android today?

While Google implements its sanctions, which will take effect in 2026, users can independently monitor why their phone is draining quickly and take steps to improve its battery life.

• Turn on Adaptive Battery: Available on Android 9 and above, this feature uses machine learning to predict which apps you’ll use next and limits battery usage to those you rarely open.

• Per-app optimization: Go to battery settings, find the specific app that you think is draining your phone quickly, and set its background activity limit to “Optimized” or “Limited.”

• Use Doze mode: This built-in feature activates when the device is stationary, the screen is off, and not charging. Doze limits network access and postpones background tasks for most apps.

• Control permissions: Regularly check which programs are allowed to run in the background, use geolocation, or send notifications without restrictions.

The Future of Android Battery Life

Strengthening enforcement of the “Excessive Partial Wake Locks” metric demonstrates that Google is prioritizing app performance and Android battery optimization, alongside preventing crashes and ANR (Application Not Responding) errors. The new policy, the result of collaboration with Samsung and in-depth analysis of real-world data, creates a transparent environment where apps that consume significant battery life will be publicly identified. This is a significant win for end users, as it will ultimately lead to longer device battery life and improved overall platform satisfaction.
