Anyone else's iphone 5 battery going flat really quick these days?

It used to last all day no problem but it seems to only last 2/3 of the day now

Depends what apps you run on it and how much you use it etc.

You need to SWITCH OFF ANY APPS that you aren't using, TURN DOWN the Screen Brightness etc. To MAXIMISE the Battery Life!

Mine seems to be lasting not quite as long; nothing major though. It's likely I probably just changed my brightness or something.
