How to Check Android Battery Health

Step by step

1. 1 min

   Access the internal test menu

   Open the Phone application on your Android device. Type *#*#4636#*#* on the dial pad to trigger the hidden testing interface. If the code does not execute, your device manufacturer has restricted access to this menu.

   Note: This code functions primarily on stock Android or AOSP-based firmwares.

   Review battery status information

   Select Battery information from the menu list. Review the fields provided, specifically looking for Battery health, which should report as Good if the cell is functioning within design specifications.

   Use AccuBattery for detailed metrics

   Download and install the AccuBattery application from the Google Play Store. This app calculates battery capacity by tracking charge current and voltage changes over several charge cycles. You must use the device for several days after installation to generate accurate data.

   Note: Third-party apps provide more granular data than the restricted system settings menu.

   Check system settings for battery usage

   Navigate to Settings > Battery > Battery usage. Observe the application list for abnormal power consumption patterns that indicate high battery drain. Constant high usage from background processes often mimics poor battery health.

   Note: Look for apps running in the background while the screen is off.

   Compare capacity against factory specifications

   In the AccuBattery Health tab, compare the Estimated capacity against the Design capacity listed on your device's original packaging or manual. If the Estimated capacity is below 80 percent of the Design capacity, the battery has reached a degraded state requiring replacement.

   Note: Lithium-ion batteries typically show significant performance drops once they fall below 80 percent of their original capacity.
