I mean : the app don't uses power -> yes it's just a reg modification
but it toogle wifi always on : and wifi eat battery
I already have a wifi toogle program
I'll give you some exemple of my use :
I regulary use my hd2 as remote control (using Gremote), I don't want wifi to be forced always ON, it uses battery.
before, when I pressed on the screen, it switched on screen and activated wifi (which was on standby) allow me to change volume and so on.. after a few seconds, the device went on standby.
Now it uses much battery when I watch a film for exemple because wifi is enabled during 2h

.
Basically, I installed WifiNoStandby for listenning to music using GrooveMoible.
Before it streamed the track, then wifi detected that there is no connection need so standby. So my play was stopped at each track.
Now it's ok but I'm looking for something allowing me to enable/disable that WifiNoStandby.
I suppose it could be possible using your way because it modifies a few registry key and it's effective without restarting. So the opposite should be possible.
Maybe the same program but in the opposite, resetting the default value ?
Do you understand what I mean ?
