have you guys calibrated battery? either via recovery or with the app? My battery life has dropped off significantly since I did, wondering how long it takes to come back I have some news about battery calibration while using Team Win Recovery: After you 'calibrate' the battery by either using Battery Calibration from the market or via your recovery you are supposed to charge the battery to 100% and then let the phone completely die on battery. After it dies you will need to plug it into the charger for 10-20 minutes until Team Win Recovery will let you unplug the power cord and then power on the phone. After the phone dies and you plug in the charger Team Win puts the phone in recovery mode, meaning that you cannot power on the phone until the charger is unplugged. And you cannot use the volume rocker or power button while in this recovery mode. It's just useful info as it scared me the first time. if you adb during this time you will see that the phone is in recovery. I'm sure Team Win will fix this soon.
