Ok, thats why I have important stuff in color on top of my thread....
SOMETIMES, these stuff happen, Reflash the ROM, drain battery completely, recharge it fully without turning on the phone, then use a battery recalibration app on market, drain battery completely, and recharge battery fully without turning on phone. Keep on doing the drain completely and charge with phone off routine two or four times, it should extend your battery life after by a couple minutes.
