I noticed that I needed to charge my Iphone4 more than I thought I would need to. So yesterday I looked at my usage and didn't understand why it was so high after just charging it. So I just charged the phone overnight again and was just looking at my iPhone4 usage time. I can't believe what I'm seeing. It show a total of 3hrs of Usage and 1Days worth of standby. I have made no phone calls today. I had my phone replaced on Monday and its shows a total lifetime calls at 10 days. WHAT? I maybe have 1hr of total talk time since monday. Am I missing something? Is the Lifetime call time based on the sim? Even if that so, I have not made 10 days worth of calls, I mean the phone hasn't even been out for 10days.
