I have my backlight all the way down(which isn't bad at all), no email synching, 1 widget running, CDMA network only, and disabled running services im not using. One day ive gone 24+ hours and been at 20-30% battery when i plugged it back in for the night, and another day i've had it last 10 hours max.
If you read my earlier post I did have concern on my battery life. After reading the posts here and using some of them, I have much improved longevity each day. I came from the BBB Storm 2.
I had my phone running all day yesterday, made a few calls, nothing too long. I do have the extd battery in it and so between 7am to 8pm it used 10% of the battery. I have WiFi off because I am not using it where I am.
I'm having somewhat better luck with setCPU lowering my clock when the phone is in my case.
