Hi Lathiat. Why do you need to disconnect from the current network? I can think of many alternatively implementations which would meet most requirements that have been proposed, like turning the wifi back on when the battery is charging or at 5am. All the proposals involve compromises, but it seems much easier to make a notice that clearly says "Wifi will reconnect at 5am" then to say "Wifi is still using your battery, but we've disconnected from the current network". I mean, the message itself fits in the same space as the current message, and the icon itself could have a timer band counting down till 5am so you know that it's only temporarily disabled. (I too have accidentally used up all my month's data because I left the wifi off for a few days. It's not nice. I'd appreciate a feature which deals with it. But this one is unpredictable, unreadable and confusing.)
Also, are you proposing that low power mode with wifi uses the same amount of power as lower power mode without wifi? If I know I'm not going to see a power point for many hours, I turn my phone onto low power mode and turn wifi off (and the brightness right down and some other things). I might do it as I leave the house in the morning when I still have 95% battery. In these cases, I very often need my phone most in precisely when the battery will be weakest.
