Little background: Before updating to 2.1 the battery would usually last about a day or a day and a half with moderate use(phone, texting, and social websites). I updated to 2.2 and battery drained very fast; so I hard reset and disabled Wi-Fi which helped, but still drained within a day with less than my average use(if I forgot to plug in the charger, it would be dead in the morning). I've since rooted and switched to Virtuous 2.7 with the custom kernel; which seemed to help out(with my "2.2" usage the battery life was about 16-20hrs...Wi-Fi disabled, now it's around 20-24hrs). What I noticed with the 2.2 update is "irregular" battery drainage. It would go to down to about 70%-80% fairly quick, but drain much more slowly down to about 40%, and then drain quickly to about 15%. Just a while ago, I unplugged the phone from the charger(It had finished charging earlier and I unplugged and plugged the charger again to make sure it's "topped off"), and drops to 98% in about a minute(zero use). I fire up the youtube app and watch Katy Perry's Teenage Dream(I don't like her singing but hey, it's a catchy song), and by the end of the song it's at 89% battery life. Anyone know what's causing this or know if this is normal? Right now it's still at 89%(~28mins since uplugged) I don't even have much apps on here(Aside from whatever is on Virtuous, I've only added Rom Manager, Youtube, Bank of America, and Barcode Scanner).
