I'm trying out right now if setting suspend mode to "early" helps. Supposed to eat more battery, but it's more important to me to be available. So far I've been out of the house one time and came back and Jolla managed the switch to mobile and back to wifi without any kind of problem. That might mean nothing, as sometimes it works fine and sometimes not, but maybe there is also a connection between the suspend mode and the reconnect-problems. We'll see. Edit: Looks like it eats ~25% battery in 2 hours. I would have been OK with having to charge every evening (doing that anyway), but this might be too much.
