Not sure if there is a memory cache or maybe it's the glances running in the background, but it seems after a day's use the Watch starts bogging down and now running as smoothly. It runs like new after a good power down/reset.
I haven't noticed being bogged down but I posted that after 4 days or so, my watch seems to be pretty random about asking me to unlock. Which will be an issue for some, I'm not too worried about it.
Yep. Admittedly it is only day 2 for me but I'm finding that after a while without a restart notifications become sporadic. Turn it off then on again seems to wake it back up.
