Here’s a bulleted list of actionable recommendations:* Optimize Background Activity: Implement intelligent background task management. Utilize Android’s JobScheduler and WorkManager APIs to schedule background tasks efficiently, allowing the system to batch and optimize them. Minimize unnecessary background operations and only perform tasks when truly needed.

Consider using “Doze” and “App Standby” modes to conserve power when the app is not actively used.

Manage Location Services Wisely

Request location updates only when necessary and at the appropriate accuracy level. Use the “fused location provider” to obtain location data from various sources (GPS, Wi-Fi, cell towers) in a power-efficient manner. Consider implementing geofencing to trigger location-based actions only when the user enters or exits a specific area. Provide clear user controls over location permissions and explain why location data is needed.

Optimize Network Usage

Implement efficient data transfer strategies. Compress data before transmission, use caching to reduce the need for repeated downloads, and employ adaptive streaming techniques to adjust video quality based on network conditions. Monitor network usage and provide users with options to control data consumption.

Use Wake Locks Judiciously

Avoid unnecessary wake locks. Only use them when absolutely required to keep the CPU active. Release wake locks as soon as the task is complete. Consider using the `PowerManager.isDeviceIdleMode()` method to check if the device is in Doze mode before acquiring a wake lock.

Improve Code Efficiency

Profile and optimize app code to identify and eliminate performance bottlenecks. Use efficient algorithms and data structures. Optimize graphics and animations to reduce CPU and GPU usage. Minimize the use of resources like memory and CPU cycles. Regularly test the app on a variety of devices and Android versions to identify and address performance issues.

Embrace Android 15 Battery Saver Features

Integrate with Android 15’s new battery saving features and APIs. This might include adapting to new power management strategies, taking advantage of system-level optimizations, and providing users with options to control app behavior to save battery.
