How to Clear Android System Logs and Reset Battery Stats

How to Clear Junk Logs and Reset Battery


Is your Android phone feeling slow, or are the battery usage statistics not showing accurate information? Some Samsung Android devices have a built-in diagnostic menu that allows users to clear certain system logs and reset battery statistics.

Steps to Reset Battery Statistics

  1. Open the Phone/Dialer app.

  2. Enter the code *#9900#.

  3. If the SysDump menu opens, look for Delete dumpstate/logcat.

  4. Select Batterystats Reset from the available options.

  5. Restart your phone.

What Does This Do?

The process can reset Android's stored battery usage statistics and clear certain diagnostic logs. However, it does not increase the actual battery capacity or repair an old or damaged battery.

The *#9900# code is primarily associated with Samsung devices, and it may not work on every Android phone or Android version.

Important Note

Be careful when using diagnostic menus. Avoid changing settings or selecting options you don't understand.

If your battery is physically degraded, the best solution is to check the battery health and consider professional service rather than relying on a statistics reset.
