My HTC 601 for the last few weeks has been draining ridiculously fast - and I'm tethered to a charger at work, in the car, and then at home. It was going from 100% to 0% in about 5 hours. . .somewhere around 5% gone every 15 minutes or so - so I am CAUTIOUSLY (but very optimistically) saying that I just performed this little trick and the phone has now gone down only 3% in the last hour. THANK YOU SO MUCH! :-)
