This is really one case of maybe 5, that cause drain and usage/standby problem. I get this problem when watch video in safari on ipad. When i watch in private mode, there is no problem.
Now i think one more case is apple remote in itunes and remote app on my iphone. When i set it to off on itunes and delete app all is allright.
Olso turning autoupdates to off, then signing out from my apple id, then sign in to my apple id and then turning on autoupdates is helpfull for me.
Olso was helpfull to delete all music from iphone with desktop itunes and then copy all music for one more time.
Now problem is gone for me, but looks like it come back in any time. Maybe problem is in the case that i have 2 iphones, connected to 1 apple id? Someone have Plaque Inc.? Maybe problem with this game. First i get this problem when install this game on ipad and 2 iphones...
