Samsung Galaxy Watch Ultra2 Finally Gets Its Turn in the Spotlight

Samsung decided to sit out the 2025 Ultra and push the Classic instead, but now the Ultra’s back on stage, and it looks a lot hungrier for power. The new Galaxy Watch Ultra2 is basically the same rugged package we saw before, just with a few upgrades that actually matter.

The most noticeable change is the battery. Samsung bumped the capacity up to 800 mAh from 590 mAh – that’s roughly a 35 % jump, making it the biggest cell they’ve ever put in a Galaxy watch. On paper that translates to about 60 hours of mixed‑use, which feels generous for a Wear OS device, even if it still lags behind the absurd 35‑day claim of the Honor Watch 6.

Charging stays familiar: a magnetic puck that plugs into a USB‑C cable. Samsung says the new charger can push the battery to 40 % in half an hour, still capped at 10 W, so you’ll be back on the trail relatively quickly.

On the display front, the Ultra2 nudges past the 1.5‑inch mark and now peaks at a dazzling 5 000 nits – bright enough to read in direct sunlight or underwater. Speaking of water, the watch keeps its dual‑rating of IP68/IP69K plus a 10 ATM rating, meaning it’s truly dive‑ready. Samsung even bundles a dedicated diver app, so you can log depth, time and ascent rates without pulling out a separate gadget.

The chassis remains titanium, and the screen is protected by sapphire crystal, giving it a premium feel and serious scratch resistance. The side buttons are a tad clickier than on the first Ultra, but the rotating bezel is still missing, which may irk fans who prefer a physical control over swiping.

Physically the Ultra2 is a bit slimmer than its predecessor, yet it still commands a noticeable wrist presence. At just over 60 g it’s heavier than many rivals – think OnePlus Watch 4 – but that weight comes from the robust materials and larger battery. It’s definitely designed for larger wrists, not for those who favour a discreet, lightweight timepiece.

All in all, the Galaxy Watch Ultra2 feels like a modest evolution rather than a revolution. It adds the battery life many users have been asking for, a brighter screen, and a few refinements to durability. If you’re already in the Samsung ecosystem and need a smartwatch that can handle deep dives, high‑altitude hikes, and long‑haul commutes, the Ultra2 is worth a look.
