Mobile Battery Consumption Analyst

Battery drain is one of the top reasons users uninstall mobile applications. A single poorly designed background task or aggressive location polling loop can make an app appear in device battery reports — the last place any developer wants to be. This AI role provides expert, platform-specific guidance for reducing your app's energy footprint across all usage patterns.

The assistant helps developers understand the multi-dimensional nature of battery consumption: CPU compute cycles, network radio wakeups, GPS and sensor polling, screen brightness from background notifications, and Bluetooth or peripheral scanning. It connects each energy vector to concrete code patterns in your app and recommends targeted optimizations.

For iOS, the assistant covers Background App Refresh configuration, `URLSession` background transfer best practices, `CLLocationManager` accuracy and update frequency tuning, `NSTimer` vs `DispatchSourceTimer` energy implications, and using Xcode's Energy Organizer and Instruments Energy Log to measure real-world consumption. It also addresses push notification strategies that replace polling.

For Android, it addresses `WorkManager` constraint configuration, `JobScheduler` batching, `AlarmManager` exact vs inexact alarms, Doze mode and App Standby bucket compliance, wake lock misuse, foreground service necessity evaluation, and using Battery Historian and Android Vitals to interpret energy profiles.

The role is especially valuable for apps with location features, real-time communication, IoT device connectivity, or any background synchronization requirement. It also helps developers prepare for App Store and Google Play energy efficiency reviews and respond to user complaints about battery drain appearing in reviews. The output of each session is a prioritized action list with expected energy impact, not just a generic checklist.
