Having apps put to sleep for battery optimization is not done via sleep mode.</P><P>&nbsp;</P><P>Sleep mode is for the watch and phone for when you want to get some uninterrupted sleep.&nbsp; It turns on do not disturb, lowers your screen brightness or puts your phone in greyscale and disables certain features of the watch.&nbsp;</P><P>&nbsp;</P><P>If you have apps that are sleeping and deep sleeping, that is battery background usage restrictions.&nbsp; It puts apps you don't use often to sleep to prevent them from running in the background and using up your battery.&nbsp; Deep sleeping apps use even less background resources.&nbsp; Apps will operate normally even when sleeping or deep sleeping if you open them up to use them.&nbsp; You may have to re-allow some permissions when you wake them up.&nbsp; If you want to control which apps can be put to sleep, go to battery/background usage limits.&nbsp; Tap on the tile and turn on (or off) "put unused apps to sleep".&nbsp; This setting automatically takes not of how often you use certain apps and will put occasionally used ones to sleep, and rarely used ones into deep sleep.&nbsp; You can move any app into or out of sleep at any time by either selecting it and removing it from sleeping apps (or by simply opening the app).&nbsp; You an also set apps to never auto sleep.&nbsp; The fact that half your apps are asleep likely means that the auto sleep slider is on.&nbsp; As I said, the fact that they are sleeping means nothing in practical terms, as your apps will still work when you open them, so you don't need all caps help.</P> Tue, 23 Dec 2025 22:02:01 GMT nullandvoid 2025-12-23T22:02:01Z
