please someone find a way to do this! the one and only thing i miss about my blackberry!!! I feel ur phone runs better if it gets a break sometimes, but my phone is my alarm so i would need it to turn on and wake me up!! someone please make this possible!!!! Root or nonRoot dont matter!
The only phones that I'm aware of with this capability are blackberries.
Why you ask? Because short of pulling the battery, a blackberry is never truly off. Instead, they go into a sort of hibernation mode which allows the phone to boot up quickly when you turn it "on" and also allows for the auto on/off functionality.
However, this is also the reason that it is suggested to pull the battery frequently on blackberry, because they don't have a task killer and manage multitasking poorly.
