Sometimes the battery life is ok, then sometimes it's insanely bad. I watched 90 seconds of a youtube video today and it drained 75% of my battery!!!!! That's crazy.
During calls, battery drain is super fast as well. A 60 minute call will take at least like 40% or more. Otherwise, in standby and texting, email it's ok. GPS and Maps drain it faster than normal but it's liveable.
I have not experienced such bad battery life with my liquid on any other roms than the MIUI ones, which seem to all have some sort of battery issue, at least for the last 2 1/2 months, I wonder if this is do to an errant system call or the proximity sensor or something... anyway, the rom is great but I don't think I can keep using it if I can't trust my phone to last 12 hours - it killed my phone today and really messed up my day.
