Do you have any taskiller, task manager, antivirus, battery apps, is it through wifi or data ?

Do the apps work on wifi? If so see if background data for all apps is enabled. Settings--Data usage--menu--Restrict background data. And also check the options for individual apps. Settings--Datausage--select the app--see if restrict background data is enabled.
