Monitor charging current in mA, track battery health, measure session stats, and get smart alerts when something needs attention.

Built for everyday use. Clear stats. Local data. No account required.

❤️ BATTERY HEALTH

Every charge session affects long-term battery wear. Charging Master helps you see the full picture:

• Estimated battery capacity and health percentage
• Charge cycle tracking and session wear
• Average discharge speed and daily wear stats
• Deep sleep, standby, and awake time insights
• Battery temperature monitoring with 24-hour chart
• Charge alarm — get notified when your target level is reached
• Low battery, high/low temperature, and high drain alerts
• Overnight unplug reminder to reduce time at high charge

📊 BATTERY USE & MONITORING

See what your battery is doing in real time:

• Live battery level, voltage, temperature, and status
• Charging and discharging current (mA) and power (W)
• Current and level charts for the last ~45 minutes
• Remaining charge time and remaining use time estimates
• Screen-on vs screen-off charging and usage estimates
• Per-app battery usage and discharge speed (with Usage Access)
• Active charge session stats: mAh added, average speed, duration, max temp

🔌 CHARGING INSIGHTS

Measure how your phone charges — and what affects it:

• See charging current in mA to compare chargers and cables
• Track speed with screen on vs screen off
• Charge time insights: typical vs guided estimates
• Session history: mAh charged, wear %, plug type, duration, temperature
• Understand how background apps, brightness, Wi‑Fi, GPS, and Bluetooth affect power use during charging

Charging Master shows real measurements from your device. It does not change hardware charging speed.

⚡ OPTIMIZE POWER USE

Reduce unnecessary drain while charging or on the go:

• Battery optimization score with a quick system scan
• Checks for battery saver, brightness, connectivity, GPS, Bluetooth, and idle drain

We're focused on accurate battery statistics and a clean, honest experience. Charging Master stores your data locally and does not require privacy-sensitive permissions beyond what each feature needs (e.g. Usage Access for per-app stats).

Note: Charging current depends on your charger type (USB / AC / wireless), cable quality, phone model, battery health, screen brightness, and active background tasks. Readings are estimates based on device sensors and may vary by manufacturer. ## Rankings - #681,396 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.ACCESS_WIFI_STATE` - `android.permission.BLUETOOTH_CONNECT` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_DATA_SYNC` - `android.permission.INTERNET` - `android.permission.PACKAGE_USAGE_STATS` - `android.permission.POST_NOTIFICATIONS` - `android.permission.QUERY_ALL_PACKAGES` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.WAKE_LOCK` - `android.permission.WRITE_SETTINGS` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.fastchargingbattery.chargingmaster.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` ## Similar extensions and apps - [Charging Master - SmartBattery](https://chrome-stats.com/d/com.batterydoctor.chargemaster) — 345,682 users, 4.56 / 5 - [Charging Master - Ampere Meter](https://chrome-stats.com/d/com.ampere.chargertester.fastcharging) — 7,901 users, 3.00 / 5 - [Ampere Meter: Charging Monitor](https://chrome-stats.com/d/com.brb.amperemeter.s) — 136,285 users, 3.38 / 5 - [Battery Master: Smart Charging](https://chrome-stats.com/d/com.bkapps.faster) — 96,009 users, 4.52 / 5 - [Fast Charging Monitor](https://chrome-stats.com/d/com.liteapps.charging) — 12,848 users, 4.43 / 5 - [Charging Meter](https://chrome-stats.com/d/com.grounsoft.charging) — 2,744 users - [Battery Master](https://chrome-stats.com/d/mr.ss.batteryinfo) — 129 users - [BatteryMeter](https://chrome-stats.com/d/com.passi.chargemeter) — 1,533 users - [Battery Monitor](https://chrome-stats.com/d/com.easy.tech.batterymonitor) — 470 users - [Charging Info - Battery Health](https://chrome-stats.com/d/com.easylife.chargingmonitor) — 1,218 users - [Battery Meter](https://chrome-stats.com/d/com.ruralrobo.batterymeter) — 3,751 users - [Battery Health Monitor](https://chrome-stats.com/d/com.pneusen.battery) — 28,165 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.fastchargingbattery.chargingmaster)
