PHBattery Guru: Advanced Battery Health & Optimization
Battery Guru is a comprehensive battery management utility for Android 7.0+ designed to monitor health and optimize longevity through data-driven insights. The application provides granular metrics by measuring real-time capacity and supporting dual-battery configurations. By tracking charging current and discharging cycles, it helps identify efficient hardware combinations and monitors wear over time.The tool features advanced monitoring of system states, including deep sleep percentages, wakelock analytics, and application-specific power consumption. Users can implement protective measures via customizable temperature and charge limit alarms. Beyond passive monitoring, the application includes a Doze editor to fine-tune Android's idle states and an extended system battery saver with configurable profiles for animations and data usage.
