i am going to try it right now, both ways.. and see what happens..
HTC One Sprint
fast boot off, no power plugged in.. nothing..
Fast boot off, charger plugged in.. nothing..
Fast boot ON, charger plugged in.. nothing, alarm set for 11:14, however, when i turned the phone on.. at 11:15 the alarm started..
Same thing with phone unplugged
