  • Power on your phone. Do not be surprised when the indicator says your battery is not 100%. Charge your device while still on until it says that the battery is 100% while on
  • Remove the charger and restart your phone
  • If after restarting it does not say 100% start charging till it reaches 100%on screen
  • Repeat the cycle until you have a 100% or something very close when you power with on without plugging the charger
