Windows Phone turns off its WiFi when the phone is locked in order to preserver power, something which users are probably aware of by now, also something which we’ve recently seen could lead to high data consumption. Android phones for instance have an option where users can select the behavior of wireless choosing whether to keep it always on even if the device sleeps or always on while charging only.
Answering a Twitter question about why “WiFi shuts off when you turn off the screen on every Windows Phone” followed by a request to fix the bug, Joe Belfiore replied with the following comment:
@ssimpson205 Someone is gonna yell at me for saying this, but…fix is coming. :)Sshh.Just promise me a little patience though.
