About this app

3C NG Battery gives you a complete view of your Android battery — its current status, history, estimated runtime, charging behavior and long-term health.

Built from the ground up for modern Android, it combines detailed monitoring with customizable dashboards, smart alerts, Wear OS support and a unique way to compare your battery health with other devices of the same model.

Already use 3C Battery Manager or 3C All-in-One Toolbox? They can be recognized automatically and your existing battery history can be imported in one tap, so you can start fresh without losing years of data.

MONITOR YOUR BATTERY IN DEPTH

• Live battery status with percentage, charge/discharge trend, temperature, voltage, current, capacity, remaining time and time-to-full estimates
• Detailed history with percentage, voltage, current or power, and temperature graphs
• Up to four graph panels with pan, zoom and quick 24h, 48h and since-plugged views
• Drain estimates based on overall, screen-on and screen-off usage
• Charging estimates by charger type, including AC, USB and wireless
• Battery aging analysis with estimated real capacity compared with rated capacity
• Charge and discharge cycle history
• Manual timeline markers plus automatic markers for plug/unplug events, profile changes and reboots
• Fully customizable dashboard: choose which cards are shown and arrange them in your preferred order

GOOGLE PLAY VERSION

Google Play restricts permissions that allow apps to access installed applications or install additional app packages. Because of these restrictions, the Google Play version cannot include some advanced features available in other distributions of 3C NG Battery.

This includes per-app battery statistics, wakelock analysis, and downloadable notification icon packs used to display more expressive battery information directly in the status bar.

All core battery monitoring, history, health analysis, alerts, Community Compare, Wear OS integration, widgets and notifications remain available.

SMART BATTERY ALERTS

Create your own monitoring rules using any combination of battery percentage, voltage, current, temperature and charging state.

Rules can be enabled, cloned, reordered and copied to another paired device, giving you precise control over when the app should alert you.

COMPARE YOUR BATTERY WITH THE COMMUNITY

Compare battery information between your own devices, or optionally participate in Community Compare.

When anonymous sharing is enabled, 3C NG Battery can show how your battery health compares with other devices of the same model, including typical capacity, charging behavior and drain estimates.

Sharing is:

• Off by default
• Enabled separately for each device
• Anonymous and revocable at any time
• Limited to aggregate battery metrics

No account, location, device identifier or raw battery history is shared.

WEAR OS SUPPORT

Pair the app with the free Wear OS companion to:

• View your watch battery directly from your phone
• Keep a persistent watch battery status notification
• Automatically synchronize battery history between phone and watch
• Monitor phone and watch together from the same dashboard

WIDGETS & LIVE NOTIFICATIONS

Add battery information directly to your home screen with:

• Gauge widgets
• Data-cell widgets
• Live battery graph widgets
• Customizable themes

You can also keep a persistent battery notification with configurable icon style and refresh rate, plus a pinned shortcut showing live battery information.

BUILT FOR PEOPLE WHO WANT TO UNDERSTAND THEIR BATTERY

Whether you simply want to know how long your phone will last, track battery wear over time, investigate unusual drain or compare your battery with others, 3C NG Battery puts the information in one place.

Built by the developer behind 3C Battery Manager and the 3C Android tools — reimagined for a new generation of Android devices.
