I have a Nexus 7 2013 LTE (4.4.2) on which I have created a restricted profile for the kids.
My problem is that after "logging out" from the kids profile the profile still keeps the device active (the detailed battery history shows the device as active) and the battery drains with more than 1% per hour. After a reboot it becomes normal again, using the normal profile does not cause the problem.
To reproduce the problem all I have to do is log on to the restricted profile and then directly log off without starting any apps at all.
Does anyone else have the same problem? Is there a solution? Google did not find an answer for me.
