Have you looked at how Safari works? The fact that it now uses a timeout 
to end TLS sessions, that are lingering or deemed "potentially inactive" 
? Have you looked at this UX experience on iOS?

Just asking as I've looked an the Android and your sketch, but don't 
sense evaluation of iOS.

Apple is pretty good at UX. Sometimes they do enough just to be better 
than the competition, so I do tend to look at them first in regards to 
UX matters, ditto as the place to trigger changes that ultimately 
percolate to competitors etc..
