I have the wifi turned off and uninstalled as many of the apps as it would let me. Several I cant seen to uninstall because they are not showing up in the settings where you have to go to uninstall them. The screen is showing the most usage. it was also fully charged last night when I went to bed and this morning it was so drained it wouldn't turn on. I didn't turn it off though I had the sleep function come on after 5 minute of no use
