My latest battery usage profile said I went from 99percent to 35 percent in 1 day 16hrs and 14mins. Average idle for me was 13mA. I can usually get almost two days of life out of mine when I use it like I want. I'm always connected to wifi on a daily basis except for commuting. My brightness is all the way up, OC'd to 1200mhz, standby screen on with billboard, meecast updating every hour, and message screen mod to black. I do use it very little for internet because I'm almost always near a real computer, and I don't use it for e-mail. I average about 5 calls a day, and listen to some music at work as well. Battery life dramatically shortens to a little less than 24hrs when I text a lot though. Anyone think it would be a good Idea to use profilematic possibly to change frequencies/current draw depending on battery life and/or usage? Didn't know if it would be negligible or a waste of time. Just a thought though.
