The answer to how to check battery health in Android phones depends on their OEMs. However, the overall steps involved in checking the battery health in Android phones of different operating systems are almost the same.

Method 1: Use Built-in Battery Settings

Most Android devices offer built-in tools to check battery health. You can access them by following these steps.

How to check battery health in Android settings

  1. Open Settings: Go to your device’s settings menu.
  2. Battery: Tap on the “Battery” or “Battery & performance” option. 
  3. Battery Health: Look for the “Battery Health”, or “Battery Status” or “Battery Usage” option. Here, you can see your battery’s current condition, estimated battery capacity, and the Battery consumption over the last 24 hours and the last 7 days along with the apps that have been utilizing the most amount of battery power.

If you see any app consuming more battery power than usual, you can stop such apps from utilizing more battery power by force closing them, putting them to sleep, or disabling them. This extends your Android phone’s battery life significantly.

  1. Navigate to your phone’s dial pad in its default phone app.

  3. Your phone should open up a new kind of diagnostic menu as soon as you type the last ‘ * ‘ symbol. 
  4. Search for battery information in the new diagnostic menu. 

If the menu doesn’t show up, then the chances are that your phone doesn’t support such codes by default settings. If the menu doesn’t show and you do find the battery information, then you’ll be able to see the data like your battery’s percentage, the health of the battery, and the temperature of the battery etcetera.
