Android Battery Usage

Measures the % of battery capacity consumed by the app in a session. Calculated by dividing total battery discharged (mAh) over Device’s Battery Capacity.

How does it impact user experience

Users abandon apps using excessive battery. Similarly, Android could kill apps using excessive battery. As per a Techbeacon survey, over a third of the app users (36%) had actually stopped using a mobile app because of heavy battery usage.

Threshold Guidelines

Recommended thresholds is <= 0.5% of battery consumed per minute

How to improve Battery Usage

Following are the recommendations to improve Battery Usage :

• Optimize app wake locks: Use wake locks judiciously and make sure to release them when they’re no longer needed.
• Use JobScheduler: Use JobScheduler API to schedule non-urgent work to happen when the device is already awake and connected to a power source.
• Use AlarmManager judiciously: Use AlarmManager API only when it’s necessary, and be mindful of the time intervals at which you set the alarms.
• Monitor network connectivity: Monitor network connectivity and adapt app behavior to avoid battery drain when the network is flaky.
• Use Battery Historian: Use Battery Historian to identify power-hungry code paths and optimize the app’s resource usage accordingly.
