OKAY IMA STOP U RIGHT THERE u NEVER...EVER charge a li-po battery for more than 30min after it is fully charged THAT KILLED THE LI-PO CELLS I KNOW THIS AS I HANDEL LI-POS EVERYDAY BECAUSE OF MY HOBBY, so u might have already killed the battery if not it will soon be. so DONT CHARGE IT OVER NIGHT FOR THE LOVE OF GOD U RUINED IT BY YOURSELF and also turn yourphone off everynight it gives the battery a breather, also never charge it when the back of the phone is warm as this will also kill it, try not to use it when it is charging (VERY IMPORTANT), and the reason for this is because when it is hot that means it is discharging quickly and if u r to plug it in when it is it is discharging fast it will be charging at the same time, NOT GOOD THIS WILL ALWAYS DECREASE BATTERY LIFE
