Never got one to work, in the selection process it's like galaxy phone, buds, ring, other devices etc etc etc.... Plus why is there not jus one big fat a$$ batt icon avail in widget form!? I mean come on Samsung... Pretty basics stuff...
thas mine btw...
New widget fully charged, rebooted, same result.... 
Update... All of the Samsung provided ones continue to not work, went with a 3rd party an whaddya know... Does EXACTLY as expected, the L/H one is on the always on display lock screen, the R/H is on my main homescreen, you can have it as big or as little as you like on both.... V. Simple, no? You'd think Samsung woulda thought of something so simple.... 🙄
