Battery Analyzer

⚡ Battery Analyzer is a real-time battery monitor and charging monitor for device-reported battery current, charging sessions, temperature, level, and voltage.

See how the net current entering or leaving your battery changes while charging or discharging. Follow live battery statistics, explore charging charts, and review locally recorded charging history in one place.

IMPORTANT: Current values are device-reported net battery current in milliamps (mA), not a measurement of the charger's direct output. Reading availability, update frequency, and accuracy depend on the device, Android version, and manufacturer.

📈 LIVE BATTERY CURRENT MONITOR

• Monitor device-reported charge and discharge current in mA

• Readings update approximately once per second when available

• See minimum and maximum recorded current for the active session

• View a live charging chart over 60 seconds, 10, 60, or 120 minutes

• Choose a smooth trend line or collected current samples

• Check battery level, voltage, and battery temperature

• See the Android-reported plug type: AC, USB, Wireless, or Dock

• Follow the session timer from plug-in or unplug

• Enable an ongoing notification with current, level change, and elapsed time

🔬 CHARGING PROFILE BY BATTERY LEVEL

Analyze recorded charging behavior across ten battery-level ranges: 0-10%, 10-20%, and onward through 90-100%. Each range shows its average device-reported battery-current reading.

• See the highest range average and the average for the 50-60% range

• Observe how recorded charging current changes as the battery fills

• Compare recorded behavior from different chargers or cables range by range

• Build long-term averages from retained charging sessions

• Review duration, average readings, highest range average, and sample count for each session

📜 CHARGING AND DISCHARGING HISTORY

• Keep up to the 199 most recent charging and discharging sessions

• Review start and end battery level, duration, and recorded current range

• Use the level track to see where each battery session began and ended

• Follow an in-progress session while battery monitoring is active

🔋 BATTERY INFORMATION

Battery Analyzer displays values reported or exposed by Android and the device. Depending on device support, additional information may include battery technology, Android-reported battery condition, and available RAM. Unsupported values are hidden rather than estimated.
