I just noticed something weird?

Ok so when I use my iphone my usage and standby time go up. They sometimes even become identical. How do I fix that? Is it a software bug(iOS7.0.4) or is it the battery? I've tried full restore a couple of times but to no avail.

If you're checking your usage constantly, then only your usage would go up.

If you're checking your usage, using other apps, putting your phone to sleep, or just leaving it for a few minutes, and checking it again, your standby time would go up. Standby time is the time when your phone is locked and asleep.
