Charging Master :Battery Meter

Charging Master helps you understand your battery — not guess it. 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
• One-tap shortcuts to relevant system settings
• Tips to lower power consumption during charging sessions

🛠️ DIAGNOSTIC TOOLS

• Device info — model, Android version, CPU, display, RAM, storage
• CPU usage monitor with live chart
• Phone temperature and thermal status
• App manager with usage overview
• Bluetooth device battery levels (when supported)

📱 WIDGETS & NOTIFICATIONS

• Ongoing notification with live mA, level, ETA, and charge progress
• Home screen widgets: battery monitor, battery & clock, compact battery
• Optional live widget updates while monitoring

✨ PREMIUM

Upgrade to Premium for:

• Ad-free experience
• All home screen widgets unlocked
• Unlimited charge and unplug session history
• Dark and AMOLED themes

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.
