Same problem with MacBook Pro Mid 2015 (15 inch). It all started when I upgraded to macOS Monterey. Only when the mouse is turned off & on again (and connected to Bluetooth) the scrolling works once more (till laptop goes to sleepmode).

Same here, I installed WatchOS 10 yesterday during the day and it was already draining the battery on my Watch 5. This morning I started at 100% but now 2hrs later, I only have about 62% left. That is about 20% battery drain per hour! With WatchOS 9, I could go with my watch till 9 pm. with about 25% battery left. At this draining rate, I will just reach 1 pm instead of the usual 9 pm.
