Hi! A few weeks ago I noticed my battery life got significantly worse. I went into the settings and it turns out that my usage time was exactly the same as my standby time. I looked for explanations or fixes and tried everything. Eventually it was a complete reset that did it. But since today the problem's recurred. Since I couldn't find a recent thread about this issue I thought I'd make one, maybe someone has the same problem and found a fix. BTW I am using a 4S on iOS 5.1. Thanks!
