Just over a week before Samsung’s Galaxy Unpacked event in London on July 22, a fresh leak has laid out the purported specifications for the Galaxy Watch Ultra 2 and Galaxy Watch 9 series. The headline grabber: the Ultra 2 is tipped to carry an 800mAh battery, a 36% jump from the 590mAh cell in the first Galaxy Watch Ultra. If accurate, it would be one of the largest batteries ever in a mainstream Wear OS smartwatch.

That battery figure comes from a WinFuture report, shared and corroborated in part by Android Authority. Samsung has confirmed the July 22 date but has not acknowledged the watches or the leaked specs. For now, every detail is unconfirmed—and should be treated accordingly.

What the Leak Says About Hardware

The Ultra 2 doesn’t just gain a bigger battery. Samsung is reportedly trading its in-house Exynos W1000 processor for Qualcomm’s Snapdragon Wear Elite SW6100, a move that could reshape power efficiency and performance. A 480×480-pixel display, twin-band Wi‑Fi, Bluetooth 6.0, NFC, and a titanium-heavy casing round out the flagship. Water resistance is said to hit 100 meters—a step above the 5 ATM rating on the standard Watch 9 models.

Those standard models, available in 40mm and 44mm sizes, stick with aluminum cases. The 44mm variant gets a battery upgrade to 445mAh (matching last year’s Galaxy Watch 8 Classic), while the 40mm stays at 325mAh. Displays differ by size: 438×438 on the 40mm, 480×480 on the 44mm and Ultra 2. Storage options are 32GB or 64GB depending on model, with up to 2GB of RAM, and LTE variants will be offered.

European pricing surfaced as well. The 40mm Bluetooth Watch 9 reportedly starts at €409, climbing to €749 for the LTE-equipped Ultra 2. U.S. prices have not leaked, and direct euro-to-dollar conversions are rarely reliable—Samsung’s regional pricing, trade-in offers, and carrier promotions usually create a far different picture stateside.

What the Changes Mean for You

For anyone who has stretched a Galaxy Watch Ultra across a weekend and ended up hunting for a charger, an 800mAh battery is genuinely intriguing. Real-world endurance, however, depends on more than capacity. Display brightness, cellular usage, GPS tracking, and the new Qualcomm chip’s power draw will all shape the final runtime. The current Ultra already manages two days of typical use; the Ultra 2 could push that closer to three—or simply handle heavier always-on-display and LTE sessions without collapsing mid-afternoon.

Windows users shouldn’t expect a new PC integration story. Galaxy Wearable and Samsung Health remain Android-first experiences. If you pair a Samsung watch with a Windows laptop today, you rely on the phone as a bridge—and that won’t change. The only potential ripple: a more capable smartwatch could strengthen the Samsung ecosystem, which in turn might nudge Windows users who also own Samsung phones to stay loyal when upgrading laptops.

Fitness-focused buyers will note the move to 100-meter water resistance on the Ultra 2. That rating is not a universal diving certification, but it does signal greater confidence for swimmers and open-water athletes. The standard Watch 9 models keep a 5 ATM rating, which covers pool swims and rain but not high-speed water sports. Samsung’s official guidance—expected on July 22—will clarify exactly what each rating means in practice.

The Processor Pivot: Exynos Out, Qualcomm In

Samsung’s decision to swap its own Exynos W1000 for a Qualcomm chip is, historically, notable. The company had used its 5nm Exynos W920 in 2024’s Galaxy Watch 8, then refreshed it with the W1000 in 2025. A move to Qualcomm suggests the Exynos platform may not have kept pace with Samsung’s ambitions for AI-driven health features or multi-day battery life. Qualcomm’s Snapdragon Wear Elite SW6100 was announced earlier this year with a focus on heterogeneous compute, which splits workloads across power-efficient and high-performance cores—potentially a better fit for a watch that needs to juggle continuous heart-rate tracking, sleep analysis, and on-wrist AI responses.

Neither company has shared benchmark or battery-life projections for this chip in the Ultra 2, so the real-world impact remains unknown. But the mere mention of Qualcomm will carry weight with buyers who have watched some Wear OS watches from other brands outperform Samsung’s silicon in sustained smoothness and app-load times.

How We Got Here

Samsung’s smartwatch line has been on a steady battery-improvement path. The Galaxy Watch 5 Pro introduced a 590mAh cell in 2022—the same capacity that appeared in the first Ultra in 2025. Meanwhile, the smaller Watch models hovered between 300mAh and 425mAh for years. An 800mAh battery would be a leap, not a step.

The switch to a Qualcomm chip also fits a broader pattern. In 2026, Samsung’s phone business is already running Qualcomm’s Snapdragon 8 Elite globally for the Galaxy S27 series, moving away from Exynos entirely in many regions. Extending that processor strategy to wearables suggests a company-level realignment, not just a one-off experiment.

What to Do Now

If you’re eyeing a new Samsung smartwatch, wait. July 22 is close, and even if the leaks prove accurate, Samsung will likely announce preorder deals, trade-in values, and bundles that could dramatically shift the effective price. Leak-based purchase decisions almost always ignore incentives that shave hundreds off the sticker price.

For current Galaxy Watch Ultra owners, the battery increase alone may not justify an upgrade unless your current watch is struggling to last a full day under your typical load. The Qualcomm chip and any new health features—Samsung has teased an AI-powered health companion—could be the real deciders, but those aren’t settled yet.

Fitbit, Garmin, or Apple Watch refugees thinking of crossing over should at least see how Samsung positions the Ultra 2 against dedicated fitness watches. The 800mAh battery and new processor could narrow the gap with Garmin’s multi-day endurance, but only if the software optimizations are there. Watch for independent battery rundown tests after launch, not just Samsung’s marketing claims.

Outlook

Samsung’s July 22 Unpacked is shaping up to be a significant wearables event. Beyond the watches, the company is expected to unveil the Galaxy Z Fold 8 and a new “shape unfurls” form factor. The Watch Ultra 2’s battery and silicon will dominate headlines, but the finer points—actual U.S. pricing, the AI health tools, and the first independent performance reviews—will determine whether the Ultra 2 becomes a genuine endurance champion or merely a spec-sheet heavyweight. Until the stage lights come up in London, treat the 800mAh figure as the most tantalizing but unverified piece of the puzzle.
