Hi I have iPhone for only three weeks. And Battery life seems quite bad. Right now I'm at 22% and I have used it just a bit less then 4 hours (attached screen shot of usage). In that time My wifi have been turned off, 3G on, and I have done some texting, emailing, browsing and about 20min of Tample Run gameplay. I just cant last full day with it. Is it somekind of damaged battery or is it normal? And how much usage do you usually get out of your device. p.s - lost 2% and I am at 20% right when I finished this.
