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 EXT SAVER tile to turn the mode on. Or to set when to automatically switch this mode
on, touch below the tile.

that affect battery usage, stop the app, and more.
