One interesting bit about this is that nothing really changes when device screen is locked - except it now tries to turn off wifi now and then. When that happens, the setting will block the attempt if sessions are in progress. That's at least how its supposed to work, I tested it only few times, maybe something else breaks it now.

I have unrooted and reset the device to see what happens. It disconnects from the WiFi after a few seconds being idle on the homescreen. It did not disconnect when I was rooted, but maybe it was KOReader. I'll try rooting again in a few days.
