If you are using a device with multiple users, some tips may only be applicable to the owner,
that is, the primary user of the device.

2 Find and tap Settings > Power management > Battery.
Using the STAMINA mode feature
Activate the STAMINA mode feature to pause your WLAN connection, data traffic
and several power consuming applications when your screen is inactive. You can
also set up an applications list to allow some applications to keep running when your
screen is inactive. Once the screen becomes active again, all paused functions are
resumed.

primary user, to activate or deactivate the STAMINA mode feature.

Estimating the standby time of your device
Standby time refers to the amount of time the battery can last when your device is
connected to the network but is not in active use. STAMINA mode, when activated,
continuously evaluates the remaining standby time, which can vary depending on
how you use your device. STAMINA mode is more effective in lengthening the
standby time if you keep the screen of your device locked. If you rarely lock the
screen, you may not see much improvement in battery performance.
When you use your device for the first time, the estimated standby time may not be accurate
since there is no previous usage history to estimate from.
To view the estimated standby time
1 From your Home screen, tap
2 Find and tap Settings > Power management.
Using Low battery mode
You can activate the Low battery mode feature to save power when the battery level
is low. This feature helps you to adjust the settings for screen brightness and data
traffic so that you can reduce battery consumption.
If you are using a device with multiple users, only the owner, that is, the primary user, can
adjust the settings for Low battery mode as well as activate or deactivate the feature. Changes
made by the owner affect all other users.
