Samsung's Galaxy Watch Ultra 2 is moving to an 800mAh battery, up from 590mAh on the current model, according to a new leak laying out nearly the entire device ahead of launch. More capacity means more full days of GPS tracking and sleep monitoring without a mid-afternoon charge.
The same leak points to Qualcomm's newest wearable chip inside the Ultra 2, the same chip that surfaced in a benchmark last week beating Samsung's own Exynos processor by more than 50 percent. A bigger battery paired with a faster chip lets the Ultra 2 hold onto both battery life and performance instead of trading one for the other.
Samsung's own teaser video promises new internal hardware without naming specifics, and it uses the word "Watch" rather than "Watches," a choice that tells buyers not to expect this overhaul on the cheaper model. Every rumor about the base Watch 9 describes modest, expected changes, while the battery, chip, and internal redesign all attach to the Ultra name specifically.
Samsung has treated the Ultra line as a spec bump for two generations, and this leak reads like the line's first actual redesign, arriving alongside Samsung's confirmed July 22 Unpacked event and a lineup-wide price increase.
