HTC One - Sleep Mode; Unlocking the Screen

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
To turn off the display and switch to Sleep mode, you can:
§ Briefly press the POWER button.
§ Double-tap the lock screen.
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 by setting the
screen timeout. For details, see Setting when to turn off the screen on
page 303.
Waking up from Sleep mode
§ Press the POWER button.
§ Use Motion Launch
™
to wake up and unlock your phone directly to
an app or screen. See Waking up the phone with Motion Launch on
page 60.
Unlocking the screen
§ Swipe up to unlock the screen, swipe right to go directly to
HTC BlinkFeed, or swipe left to go to the Home widget panel.
