Is this normal? I feel ripped off having paid so much for this battery eater: Time since last full charge: Usage: 4 hours 58 minutes Standby: 1 day 11 hours I'm on iOS 5.0.1, stock firmware. 4 hours 58 minutes of chatting on FB messenger (on wifi) while playing music from my library, some maps, a little foursquare (with radar on) on 3G and just four phone calls (each one less than 5 minutes) Right now it's 1% as you can see in the screenshot. Is this normal? Feel free to post yours if you want to. Thank you.
