Tip for HTC One owners
I love this phone. The one thing I hated was the position of the power wake button. I tried a lot of apps on the Play Store that supposedly let you use the volume buttons to wake the phone but non worked ( presumably not updated for jellybean ... ). Then I stumbled on one that does work and seems so far to have minimal effect on battery life. It's called 'power on volume'. I can't be the only one who hates the power button position so I hope this helps someone.
