Optimizing Mobile App Performance and Battery Life

App Size Optimization

App size directly impacts download conversion rates — every 10MB increase in app size reduces install rates by approximately 2%. Use ProGuard/R8 for Android and App Thinning for iOS to remove unused code and resources. Compress images using WebP format and consider downloading large assets on demand rather than bundling them. Enable app bundles on Android to deliver only the code and resources needed for each device configuration. Use dynamic feature modules to defer downloading rarely-used features until they are needed.

Battery and Memory Optimization

Battery drain is the number one reason users uninstall mobile apps. Minimize background processing — use WorkManager on Android and Background Tasks on iOS for efficient background execution. Batch network requests rather than making frequent small calls. Reduce location tracking frequency and accuracy to the minimum your feature requires. Implement efficient image loading with memory caching and disk caching to avoid re-downloading and re-decoding images. Monitor memory leaks using Xcode Instruments for iOS and Android Profiler, paying special attention to retained fragments, unregistered listeners, and closure captures.

• Background optimization: Use platform-specific APIs for efficient background processing
• Network batching: Combine multiple API calls to reduce radio wake-ups
• Location efficiency: Use significant location changes instead of continuous GPS tracking
• Memory management: Profile and fix leaks from retained references and unregistered listeners
