iphone not going on standby?

[Doobz]

I haven't been using my phone heavily today, and I noticed it a huge drop in battery when I wasn't even near it. I checked my usage and it says my usage time is the same as the standby time. Should I restore my phone? I figured it could've been an app, so I just closed everything down.

Here's a screenshot.

Any ideas on what this could be?

Try restarting your iphone once in a while.
It clears out the memory and it runs smoother IMO.

I have to agree, it has happened to me a times when the "Standby Time" is the same as "Usage"

However, Standby is just when the screen is off and after having locked it.
