You probably just don't run on an extremely low battery very often. I have only experienced it when my device was displaying less than a 15% charge. It also helps if you practice good battery management, not leaving your phone plugged in all night/day. I also have a theory that people are damaging their batteries more if they are a heavy user, while the phone is plugged in. If your phone is charging and you are playing a game my phone seems to get much hotter than at any other time.
