I posted a similar thread yesterday, but this title is a lot less vague. My iPhone 4 would connect without being connected to power and I thought one of my jailbreak packages made this happen or caused it to glitch out. Then it still did it when I installed iOS 6 and that made me think some setting file carried over from the jailbreak in my backup. BUT now my iPhone 5 is doing it, but I set it up as new, so I have no idea why. Don't get me wrong, I'm not complaining, I'm just curious. For me this is awesome since previously it would hardly appear when even connected to a power source. Has anyone else had this happen to them? Also, is this a potential battery life killer? Of course I know that I'll use more battery life when syncing over wi-fi, but not connect to a power source. I'm part of the 8 hours usage and 24 hours usage group, so I'm not getting bad battery life at all. Does it use up more battery life just sitting there in iTunes when not syncing? People claim it to be a battery killer, but when your phone disconnects from wifi when asleep I can't understand how it could have that big of an impact.
