connection, NFC and GPS) which are not in use.
 Shorten the screen turn off time. See Screen Timeout Settings.

Saver Mode and Battery Optimization.
ENTER AIRPLANE MODE
You can enable Airplane mode to have all the wireless radios (including call functions, data
connections such as Bluetooth, Wi-Fi and 3G/4G) on your handy terminal turned off, which
will considerably reduce the power consumption of your battery.
1) To enter Airplane mode, use two fingers to swipe down from the top of the screen
to open Quick Settings.
