5.17. Power Saver
Power Saver helps increase battery life by turning off or limiting certain features,
for example, turning off some background apps to pause background syncing,
turning off Vibrate on Touch, and dimming the screen. Using Power Saver can
give you at least extra 30 minutes to use the phone.
Turn on Power Saving. The phone will let you know when your battery level
goes down to 20%, and again at 10%, and will ask you to turn on Power Saving.
The battery indicator in on the top right corner will turn blue while Power Saving
is enabled.
