It provides users with more detailed information about which apps are consuming the most power in the background and gives them greater control over these apps. This includes the ability to prevent apps from running in the background altogether, or to put them into a “restricted” state where they can only perform essential tasks.

For example, if you rarely use a social media app, Android 13 might automatically limit its background activity, extending your battery life without impacting your primary use of other apps.

Doze Mode and App Standby: System Handling

Doze mode and App Standby are essential features for extending battery life when your device is idle. The implementation and effectiveness of these features have been refined between Android 11 and Android 13.In Android 11, Doze mode was activated when the device was stationary and the screen was off. It entered a deeper sleep state over time, batching network requests and delaying app syncs to conserve power.

App Standby put infrequently used apps into a restricted state, limiting their access to resources. However, the system sometimes struggled to balance aggressive power saving with timely notifications and background tasks. Some users experienced delayed notifications or missed updates.Android 13 refines both Doze mode and App Standby. It optimizes the timing and frequency of background activity to minimize power consumption while ensuring that important notifications and updates are still delivered promptly.

It is more intelligent about differentiating between essential and non-essential background tasks. For example, the system might allow a weather app to update its information periodically while severely restricting the background activity of a game you haven’t played in weeks. The end result is a system that is better at preserving battery life without sacrificing the user experience.

Android 13 Power-Saving Features

Here’s a concise overview of the key power-saving features introduced in Android 13:

• Enhanced Background Task Management: More aggressive restrictions on background app activity, including stricter limits on the use of location services and the ability to prevent apps from running in the background altogether.
• Optimized App Standby Buckets: Improved categorization of apps based on usage frequency, allowing the system to prioritize power savings for infrequently used apps.
• Adaptive Battery Improvements: Further refinement of the Adaptive Battery feature, which learns from user behavior to optimize battery usage based on app usage patterns.
• More Granular Control: Users gain more insight into app battery consumption with enhanced information displayed in the system settings.
• Reduced CPU Usage: Optimizations at the system level to reduce overall CPU load, which leads to lower power consumption.
