I don't have any mobile data network where I am, so I need to keep connected to my wifi connection all the time to get emails, etc. Unfortunately, everytime my phone goes into sleep mode, it disconnects from wifi shortly after. I set the screen timeout to never, and now I can keep connected to wifi, but the battery wears down way faster because of the screen and I'm afraid I'll burn out my display prematurely. So I keep my phone plugged in to prevent the power loss, but it's way less convenient to do it this way. Is there some way I can stay connected to wifi, and have the display turn off automatically, like normal/default? I checked most of the settings, but maybe I missed something.
