> A near-complete spec leak puts the Ultra 2's battery at 800mAh, and Samsung's own teaser hints the biggest upgrades stay exclusive to this model.

Samsung's [Galaxy Watch Ultra 2](https://idevice.com/smart-watches/samsung-galaxy-watch-ultra/roadmap) is moving to an 800mAh battery, up from 590mAh on the current model, according to [a new leak](https://mashable.com/) 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](https://idevice.com/qualcomm-is-taking-over-wearables-60238d84). 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](https://sammobile.com/) 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](https://idevice.com/samsung-confirms-july-22-unpacked-opens-reservations) and a lineup-wide price increase.
