iPhone battery problem

[GCY]

Ok so I was playing with my phone last night with about 80-90% battery left, this afternoon after looking at my phone for the first time since last night, the battery all of a sudden discharge to least than 10%!. No wifi, edge, or push email was on. Anyone know whats the problem?

Owners have been resolving many issues by Restoring the iPhone. I did so and didn't even lose my SMS or Settings.

There are many factors which could drain the battery if you think you've got nothing on that would do that try restoring that will definately help you evaluate if there is a bigger problem.

I had some problems like this before. So I started charging my phone overnight which does not make sense but it did give me a better battery life.
