Battery saver mode, when the battery charge becomes low, a
notification prompts you to turn it on.

which include Auto-sync, Wi-Fi, Bluetooth, Vibrate on tap, Brightness,
and Screen timeout.
 After you modify the Battery saver settings to your preferences, tap the
switch (at the upper-right corner of the screen) to toggle it On (blue)
or Off (gray).

Turning the phone off

the Phone options menu appears.
2. Tap Power off in the Phone options menu.
3. Tap OK to confirm that you want to turn off the phone.
Turning the screen on using the Knock Code feature
If your Lock screen unlock sequence is set to a Knock Code, tap your
Knock Code on the darkened screen to automatically turn the screen on
and unlock it at the same time.
TIP When the screen is in time-out and a Knock Code is set, pressing the Power/Lock Key

back off by pressing the Power/Lock Key again (or double-tap the Status Bar).

If you enter the wrong Knock Code 5 times, you'll be prompted to enter a phrase to

sequence, or you can tap Forgot Knock Code (at the lower-right corner of the screen)
to enter your Google Account log in or your backup PIN to unlock your phone.
