the most draining is the running apps. click your home button twice, frequently it will show what programs are running, hold one down until they shake. and click on them to stop them from running. I do this evry couple hours out of habit now!

Also turn off all your notifications except for calls and messages. You don't need all these programs running you can just click on them when you want. It is very important to turn off the stockmarket ticker and the weathr browser, because unless you turn them off they are constantly running in the background.

also, delete messages etc., often.

I guarantee once you do that it will last all day.
