Doze and App Standby
Doze and App Standby are powerful and convenient built-in modes which improve your
battery life significantly by reducing battery consumption when you are not using the
device or certain apps.
Doze
Doze suspends battery draining network activities, such as location services, syncing
and Wi-Fi® scanning in the background when you have not been using your device for a
long time.
Phone calls and SMS messaging are not affected.
Doze is activated when all of the following conditions are met:
•
Your device’s screen is off,
•
Your device is not charging,
•
You have not used your device for more than
1
hour.
Doze is canceled when you resume using the device. The mode is also paused
periodically when the device is being updated.
This feature is enabled by default and is recommended for best performance. However, if you
wish to make exceptions for certain applications, see
To make specific applications exempt
from optimization
on page 32.
App Standby
App Standby suspends the network activity of unused applications in the background,
thus preserving battery life for the activities that are important to you.
Phone calls and SMS messaging are not affected.
App Standby marks an app as idle if:
•
The app has not been used for more than
2
days.
•
The app has not shown a notification for more than
12
hours.
This feature is enabled by default and is recommended for best performance. However, if you
wish to make exceptions for certain applications, see
To make specific applications exempt
from optimization
on page 32.
