I was considering getting a Samsung Galaxy Watch 3 for my son (young teen), as he doesn't have his own phone, but I read that you can do most of the stuff over wifi, the only thing really being he couldn't track workouts on GPS, which really isn't an issue. I was hoping there'd be some sales on for Black Friday, but I'm only seeing deals for the Samsung Galaxy Watch 4. I haven't found similar writeups for the Galaxy 4, so it might be the same, but I can't tell, everyone assumes you have a phone that you'll be using it with (which is fair enough)
He doesn't have a specific need, just that he'd like a watch, and I just think he'd enjoy the gadgety side of things, steps, workouts etc. He could always use my phone to set things up if he had to, just as long as it didn't need it all the time. Also, when it says you can download songs onto your phone, I gather that is to play through some other bluetooth device it's paired with? I gather the watches wouldn't have speakers of any kind?
It's probably pretty obvious that I don't know much about smart watches, so I'd appreciate any guidance - as to that one, or other ones, although not Apple.
(I have read about the annoying battery, don't really know enough to see if it would be a deal breaker)
The watch will not do anything meaningful if you don't have a phone. there won't be notifications, no downloadable watch faces, no weather, no music, and no 3rd party apps.
In fact the smartwatch cannot be setup until it's been paired with a phone, and it won't even show you the time (since it doesn't know it). Time on the watch is sync'ed with smartphone.
