BatStats

BatStats is a comprehensive battery monitoring and analysis app for Android that goes beyond basic battery percentage tracking. Whether you're a power user wanting to optimize battery life or a developer debugging drain issues, BatStats provides the insights you need.

Core Features:

• Real-time Monitoring - Live tracking of battery level, current draw (mA), voltage, temperature, and power consumption with customizable sampling intervals (5-60 seconds).

• Session Tracking - Automatically or manually track charging and discharging sessions. Get detailed statistics including estimated capacity, average current, and duration for each session.

• Per-App Drain Analysis - Two modes available:

• Heuristic Mode: Uses Usage Stats to attribute drain to foreground apps
• Enhanced Mode: Uses Shizuku for accurate per-app power breakdown from system battery stats

• Detailed Statistics Screen - Comprehensive battery analysis powered by Shizuku (no root required):

• Per-app power breakdown (CPU, wakelock, network, GPS, sensors, camera, Bluetooth)
• Wakelock analysis (app and kernel level)
• Network usage per app (mobile/WiFi)
• Alarm, job, and sync statistics
• Signal strength distribution
• Doze/idle statistics
• Process CPU times

• Root Statistics - For rooted devices, access kernel-level data:

• Battery cycle count
• True capacity vs design capacity
• Battery health percentage
• Native kernel wakelocks
• CPU frequency states and time-in-state
• Thermal zone monitoring

• Smart Alarms - Configurable notifications for:

• Charge limit reached (protect battery longevity)
• High temperature warning
• High discharge rate alert

• Home Screen Widgets - Three widget types:

• Battery level percentage
• Current temperature
• Estimated time remaining

• Privacy Focused - All data stays on your device. No accounts, no cloud sync, no tracking.

Permissions:

• Foreground Service: Required for continuous monitoring
• Shizuku (optional): For enhanced system statistics
• Root (optional): For kernel-level battery data
