Sleep mode

Sleep mode saves battery power by putting HTC One into a low power state while the
display is off. It also stops accidental button presses when HTC One is in your bag.
Switching to Sleep mode
Briefly press the POWER button to turn off the display and switch to Sleep mode.
HTC One also automatically goes into Sleep mode when it's left idle for a while.
You can change the time before HTC One sleeps in the Display, gestures & buttons
(or Display & buttons) settings.
Waking up from Sleep mode
To wake HTC One up manually, press the POWER button. If you've set up a lock
screen, you need to unlock it.
HTC One automatically wakes up when you have an incoming call.
For many screens, you can
automatically change the screen
orientation from portrait to
landscape by turning HTC One
sideways.
When entering text, you can turn
HTC One sideways to bring up a
bigger keyboard.
