Two secret codes can help recalibrate your phone’s battery and fix common issues like false percentage readings or voltage problems:
- **Code *#0228#**: This code opens the battery status menu. It fixes voltage and level issues, ensuring your battery charges correctly and lasts longer. When you dial this code, tap "Quick Start" then "OK" to restart your phone.
- **Code *#99229#**: This code resets your battery stats. Over time, your phone may show incorrect percentages (like 50% instead of 40%), leading to unexpected shutdowns. Resetting stats corrects this for accurate readings.

Using the codes alone isn’t enough—enable these settings to maximize battery life:
