With every iPhone since the first back in 2007, I seem to have battery issues with at least one handset. My iPhone is currently at 49% charge and I took it off charge a couple of hours ago. I used it to make a call for about half an hour and then browser the web whilst travelling. Nothing else. To me it seems to be losing charge more quickly throughout the day now than when purchased a couple of months ago. Here's the stats. Usage since last full charge: Usage: 1 hour, 54 minutes. Standby: 2 hours, 13 minutes.
