Battery drain - internet

[weamish]

Phone went to shutdown overnight, battery completely drained. Usage shows 47% internet, 6 hours CPU. Can't figure out why there would be any internet usage - Google Play auto updates turned off, 3G is off, phone was off all night. Any ideas? Thanks!

Have you turned on the background restrictions.? Some app uses too much data in Background. Check this settings in App Manager.
