Accu​Battery 2.1.4

AccuBattery provides battery usage information and measures battery capacity (mAh) based on scientific methods.

BATTERY HEALTH

Batteries have a limited lifespan. Each time you charge your device, it wears out the battery, reducing its total capacity.

• Use our charge alarm to remind you to unplug your charger.
• Discover how much battery wear occurred during your charge session.

BATTERY USE

AccuBattery accurately measures actual battery usage by utilizing information from the battery charge controller. Battery usage per app is determined by combining these measurements with foreground app information. However, Android's pre-baked profiles tend to provide highly inaccurate numbers.

• Monitor how much battery your device consumes.
• Determine the active and standby use time of your device.
• Identify the power consumption of each app.
• Check how often your device gets awakened from deep sleep.

CHARGE SPEED

Use AccuBattery to find the fastest charger and USB cable for your device. Measure the charging current (in mA) to determine the optimal charging speed.

• Check how fast your device charges with the screen on or off.
• Know the duration required to charge your phone and when it's fully charged.

HIGHLIGHTS

• Measure real battery capacity (in mAh).
• Track battery wear with each charge session.
• Analyze discharge speed and battery consumption per app.
• View remaining charge time to know when your battery will be charged.
• Determine the remaining use time of your battery.
• Estimate battery usage with the screen on or off.
• Check the percentage of deep sleep during standby mode.
• Receive ongoing notification for real-time battery statistics at a glance.
