Battery optimisation
Battery optimisation is a powerful and convenient built-in mode which improves your
battery life significantly by reducing battery consumption when you are not using the
device or certain apps.
This is achieved by suspending 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.
