I know there are a lot of battery usage threads out there and a lot of opinions on how to ge the most of the battery. but is there an app that will track whats really using up the battery over a time period. some days i get great usage time and some days i dont but what i dont know is whats killing the battery usage on a constant basses. i am not a fan of task killers. i know 4G drains the battery but i bought the phone for 4G otherwise i would have bought a 3G phone i should not have to turn it off to get more time. I know the droids are not the best on battery because i have an iphone and yes it last longer, but all in all all i love the droids and will stay loyal to them. but i was wandering if there is a very good battery monitor app out there that will tell me what apps are using the most battery over a period of time. If does not exist so be it but its more of a curiosity issue. i bought the the phone to use not sit and look nice so let me know your thoughts.
