I have the 3GS, the 4, the 4S, and now this 5, and this 5 has miserable battery life so far. I want to hope it's a software thing like the first-release 4S' had (which I have one of, and experienced)
Okay, yeah, that sounds wayyyy worse than what I had previously thought. Looks like it could be a dud, as my initial battery life issues were definitely not that bad. I did have a case where my phone drained 30% overnight while doing nothing, but that quickly went away.
Yeah, I'd get it swapped.
