I picked up a galaxy watch 4 on a whim and I gotta say wearos is a trainwreck. Half the value is getting notifications to your wrist but you have to have corresponding linked apps on both the watch and phone. And typing on a watch is a nightmare -- you're paired to my phone! Why aren't I using that keyboard!?
Honestly the Pebble was not that high of a bar. Keep the screen on and send me my notifications and I'm happy.
Pebble was peak smarthwatch experience for me. Simple, straightforward, e-ink display. Super bummed that Fitbit bought them out. My Fitbit Versa is _almost_ as good as the Pebble but it's still trying too hard.
I must be doing something wrong then. I wasn't getting any useful notifications on my watch until I installed all the corresponding watch apps to the phone apps. The watch runs WearOS 3.5. But either way: getting a decent experience should not be this hard.
I've got it the way I like it now but it was a lot of installing software and playing with settings. Which is fun! But it means I would never recommend WearOS to somebody who isn't geeky about Android.
Somewhere around 2 full days. I usually stick it on the charger when I sit down at my desk, and less than 30 minutes is plenty to get it back to 100%. 0 to 100 might take around an hour.
Got a galaxy 5 watch a few months ago, which was a much better purchase.
