(I saw the battery/4S thread, but didn't see one for the 5). Noticing, like others, that my iPhone 5 doesn't have the stamina it once did now that I replaced iOS6 with iOS7. As a matter of fact, when I was driving for about 30 minutes today, iPhone 5 plugged into my car stereo and charging, I noticed when I got home that it didn't gain a single percent charge, even though it showed charging. Reminds me of my iPad 3 that when it use, sucks up so much juice that the charger can't keep up and the device literally stays fixed or loses battery when used and plugged in. As i drive a lot for my job, I've always used those opportunities to "top off" my iphone but now it seems it doesnt gain anything.
