Why does my iphone 4S reboot randomly?

I'll just be on my phone and randomly the screen will turn black, and i see a little loading circle image, then i see the apple icon as if i just rebooted my phone. It seems to do this once a day.

There may be a problem with the battery. Go to the apple or at&t, sprint, verizon, etc.store. Ask them
