Ok you ready please follow my step by step instructions.There are four cycles
For the first time charging the battery.
1.After you inserted the new battery.PLace the phone on charge with the phone turned off.Depending on the phones model functions may corrupt the charge cycle if left on whilst charging for the first time.
Ok so now you are aware the phone is to be turned off whilst its charging.
Even though the phone is off whilst its charging there still should be an indication of the charging process of by a bar indicator to let you now what stage the phone has completed the charge.
2.Now when the phone indicates the battery is fully charged.Well its not probably only one out the four cells inside the battery are charged.So pull the battery out of the phone and put it back in and place it on charge again..By doing this the phone resets again with battery.You should notice the phone start charging again
3.Once the phone has indicated its charged again you can now use the phone but let the phone run down untill it turns off by its self.Do not turn it off.This is ensure the battery is empty again before the third charge cycle.
Important dont charge in between these charging intervalls as they may corrupt the battery.
4.Follow step 3 two more times and then the battery should be to your satisfaction and the phone can be charged at any time.
