I have the iPhone 5 now. Until getting this phone, I've never had a cell phone (I don't really get that many phone calls so I haven't bothered). To be honest, the battery life isn't great, but I just bought a small external battery to charge it when necessary. It was cheaper than a replacement and I didn't want to risk making a mistake in the swap. I have more than enough technical skill to do it, but since it's now my only phone I decided not to take the chance. I might do it if the battery life gets too bad.
