Improving battery time using STAMINA mode
Use STAMINA mode to automatically improve battery time when the battery reaches

screen is not active and can automatically disable Wi-Fi® and mobile data. Most
applications then become inactive. Once the screen becomes active again, your
device starts to function normally and all disabled functions resume. You can exclude
some applications and services from being paused in STAMINA mode.
