Optimize Battery Life with Power Saver Mode

Power saver mode helps to increase battery life. It reduces the usage of phone features that
drain the battery such as the display and data connection.
1. With two fingers, swipe down from the status bar to open the Quick Settings panel.
2. Touch below the POWER SAVER tile to choose which phone features to conserve
power for.
Note: If Data connection is selected, your phone automatically disconnects from the mobile
network after 15 minutes when the screen is off and the data connection is idle (no download
activity, streaming, or data usage). It reconnects and then disconnects periodically when the
data connection is idle to save battery power.
Note: Keep in mind though that the Sleep mode option for the data connection in Settings >
Power, when enabled, overrides power saver mode.
3. Touch the ON/OFF switch next to Power saver to turn Power saver mode on or off.

Use Extreme Power Saving Mode

In times when you don't need to use much of your phone, turn Extreme power saving mode on
to extend battery life longer. In this mode, standby time can last longer than usual, and you can
only use the most basic functions such as phone calls, text messaging, and email.
1. With two fingers, swipe down from the status bar to open the Quick Settings panel.
2. Touch the EXTREME POWER SAVING MODE tile to turn the mode on. Or to set when
to automatically switch this mode on, touch
Settings
below the tile.
