AccuBattery APK for Android

AccuBattery is a mobile application focused on measuring battery behavior through charge, discharge, and standby activity. It records charging current, tracks power draw while the screen is active or inactive, and estimates battery capacity in milliampere-hours based on accumulated charge sessions. The software presents battery health indicators by correlating charge levels with calculated wear data. 

AccuBattery logs foreground app activity to associate measured discharge rates with specific applications. Additional tools include remaining charge time estimates, remaining usage time projections, configurable charge alarms to help minimize long-term battery wear, and continuous notification readouts that surface real-time electrical and battery state information.

Power analytics

AccuBattery tracks battery health by recording charge sessions and calculating estimated capacity over time. Each session logs start and end with levels, charge current, duration, and inferred wear values. A configurable charge alarm notifies when a selected percentage is reached. Historical health data is retained to show capacity trends, while wear calculations are presented per session rather than as a single aggregate metric.

Battery usage tracking relies on readings from the device’s charge controller. Discharge rates are calculated during active screen use, screen-off periods, and deep sleep. The software associates foreground applications with measured power draw rather than static profiles. Wake-up frequency from deep sleep is also recorded, providing visibility into background activity that interrupts standby states. Persistent notification with live battery statistics completes the monitoring suite.

Charging analysis tools measure incoming current in milliamperes and estimate charging speed under varying conditions. Readouts differ based on screen state and connection type. Time-to-full estimates update dynamically during a charge cycle. Logged sessions allow comparison across chargers and cables, with current, duration, and percentage gain stored for later reference. However, estimations depend on device sensor reporting, which can vary in accuracy between manufacturers.

Battery intelligence

AccuBattery provides battery health estimation, discharge measurement, and charging analysis using controller-level data rather than predefined power models. It includes real-time monitoring, historical session logs, per-app discharge attribution, and configurable alerts. However, it relies on accumulated charge cycles for capacity estimates and restricted historical access in the free tier. The application does not modify system behavior and operates solely as a measurement and reporting layer.
