Step 3: Adjust Battery Efficiency

  • Use the [Increase +] or [Decrease -] keys to adjust the battery efficiency to the desired value.
  • If the number of cycles is less than 21, changing the efficiency value defaults the battery health to 100. Ensure cycles are > 20 for efficiency < 100.

Step 4: System Health Data Modification

  • Wait for the phone to shut down completely, then power it on again.
  • Check the maximum battery capacity in Settings; it should display 100.
  • To modify this value, turn off the phone, adjust efficiency, and change popup status back to [battery popup].
