Ha, my iPhone 5 did it too, as I've said. So maybe it wasn't the fast charging but something was wrong with the battery.The ONLY model I had batteries swell on was the iPhone 5 and it did it three times. Batteries were original OEM from Apple. Any service I've ever gotten on a iPhone has been from Apple.
It would seem that this issue is a particular affliction for the iPhone 5.

I replaced my iPhone 5 battery myself after it swelled up -- it was pressing against the LCD. After letting the iPhone sit for a few months, the swelling subsided. Then I replaced it. And yes, the sleeve was puffed up like a balloon. It felt like there was air in there. I'm unsure if the replacement battery from iFixit is as safe as Apple original, though.PS. During the last battery replacement I was told by the Apple genius that the battery inside the iPhone 5 has a protective sleeve. It's this sleeve that contains any battery swelling. As long as it's not punctured everything is safe. I have to assume that this is also the case with the batteries on the 5s and up and it probably is the case with the 4 and the 4s, although I do not know.
