allowing you to keep your work and private life separate.
App Twin is only supported by some apps.

apply the feature.
The twin app will then be displayed on the home screen.

Battery
Enable Power Saving Mode
Optimiser provides two power saving modes:
Power Saving mode reduces power consumption by limiting background app activity,
visual
eects, and sounds.
Ultra Power Saving mode strictly controls background apps to ensure that your device can
stay on for as long as possible. In this mode, you will only be able to use selected apps, and
all system switches, except for Wi-Fi and mobile data, will be turned o.
Go to Settings > Battery (or Optimiser > ), select a power saving mode:
When the battery level is extremely low, enable Ultra Power Saving mode. Your device will
then display a black home screen.
To add apps you wish to use in Ultra Power Saving mode, touch and select the apps
from the list. You can touch in the upper left corner to remove the apps or touch
in the upper right corner to exit Ultra Power Saving mode.
