Sleep mode

Sleep mode saves battery power by putting HTC One M9‍(‍s‍) into a low power state while the display is off. It also stops accidental button presses when HTC One M9‍(‍s‍) 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 M9‍(‍s‍) also automatically goes into Sleep mode when it’s left idle for a while. You can change the time before HTC One M9‍(‍s‍) sleeps by setting the screen timeout. For details, see Setting when to turn off the screen.

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 What is Motion Launch?.
