i have been rooted since i got the Thunderbolt but i stuck with the first rooted Froyo with Sense that came out for the Thunderbolt back in March. with that "stock" ROM, for my regular usage, with about 2 hours screen time, the phone have no problem getting to 16-18 hours to get down to 25% remaining on the battery. with that usage, screen time is usually the highest by far at around 60-70%. Phone Idle and Cell Standby are usually at 5%. i installed CM7 mainly because i started getting those Verizon update pop ups, but as soon as i did, Phone Idle and Cell Standby are taking around 45% each of battery usage. an hour of screen time is only showing to take 5% battery time. at around 7 hours, with CM7, i'm already at 50% remaining when i used to have around 75% with the "stock" ROM. i've already tried the latest Tiamat 1.0.4 kernel. i'm about to try an undervolted kernel. i don't really want to do that if i can help it but i'm wondering if there is any reason why CM7 is using so much battery for these 2 processes?
