Galaxy S10's best feature is something the iPhone XS doesn't have

Samsung's also introducing this feature across all five of its new phones, making it the largest launch of this type of tech. And after this, it's a safe bet other phone manufacturers will, too. Perhaps we'll see more examples of this at MWC Barcelona.
This also brings up a really annoying thing about most smartwatches and fitness trackers: they're dongle hell. The Apple Watch has a special magnetized charger that's not the same as standard wireless charge tech. Every Fitbit has its own unique charge dongle. It's madness, and it prevents anyone from simply dropping any watch to charge on a regular wireless Qi charger. I wake up each morning and check to see how my watch and earbud battery life is doing. That's my connected life in 2019. Sooner or later, it's charging time... and I don't carry around a bunch of chargers because I like being a normal human being (and yes, I wear watches to bed, to track sleep... except for the Apple Watch.)
