I did have 18.104.22.168, then i decided to update to the latest one. I got pretty good battery life. under normal use and good reception i could get in between 20-30hrs of life. when im at work, thats a different story...HORRIBLE reception and pretty much roaming all day. still got 7-10hrs out of it. now with 22.214.171.124, i get MAYBE 12hrs with normal use and good reception and at work its more like 3-4hrs with bad reception. so basically it cut my battery life in half. did anyone else experience this with the new ROM?? any suggestions on how to improve my battery life?
