If I remember correctly, there used to be an option to enable the battery saving mode not only manually but also automatically when the watch goes into sleep mode at night. I used to use this feature to turn off Bluetooth and Wi-Fi when going to sleep by enable automatically the power saving mode. Now I can't find this option anymore, only in the Enduro 1 but not in the Enduro 3 Manuel. Why it got removed and how can I enable the power saving mode automatically when I am sleeping.
