Samsung Galaxy Watch Ultra 2: The Battery Upgrade That Finally Earns the Ultra Name

The new Galaxy Watch Ultra 2 directly addresses that problem. Samsung has installed a significantly larger battery, increased the display brightness, upgraded the processor and made the watch thinner.

That combination could make the Ultra 2 one of the most compelling premium smartwatches available to Android users.

This is a launch analysis based on Samsung’s published specifications and early independent testing—not a hands-on review.

The Quick Verdict

The Galaxy Watch Ultra 2 appears to be a meaningful upgrade for people coming from an older Galaxy Watch, particularly anyone who wants longer battery life, a highly visible outdoor display and serious fitness tracking.

Owners of the original Galaxy Watch Ultra have a more difficult decision. The Ultra 2 is clearly better, but the improvements may not justify spending $699.99 unless battery endurance, diving support or improved comfort matters considerably to you.

Reasons to buy

• 800mAh battery
• Up to 60 hours with the always-on display enabled
• Exceptionally bright 5,000-nit display
• Thinner design
• Dual-frequency GPS
• Titanium construction
• LTE connectivity
• Professional diving support
• Wear OS 7 and One UI 9 Watch
• 64GB of storage

Reasons to wait

• Expensive at $699.99
• Available only in a large 47mm size
• No physical rotating bezel
• Original Ultra owners may not gain enough to justify upgrading
• Some features work best within Samsung’s ecosystem

The Battery Is the Real Story

Samsung increased the battery capacity from 590mAh in the original Ultra to 800mAh in the Ultra 2—a 35% increase.

Samsung rates the watch for up to 60 hours with the always-on display enabled. Real-world battery life will naturally vary according to GPS use, LTE connectivity, workouts, notifications and health monitoring, but the larger cell represents a major improvement on paper.

Early independent testing also suggests battery endurance is the Ultra 2’s strongest upgrade.

A smartwatch designed for hiking, running, cycling and diving should not need constant attention from a charger. The Ultra 2 finally looks capable of delivering the multi-day experience expected from a premium outdoor watch.

Samsung Made It Thinner Too

A larger battery normally creates a thicker or heavier device. Samsung instead redesigned the internal structure and reduced the watch’s thickness by approximately 12% compared with the previous generation.

The watch measures 47.4 by 47.1 by 10.7mm and weighs 61.5 grams without its band. It is still a large watch, but the slimmer body and redesigned bands should make it more comfortable for exercise, sleep tracking and continuous health monitoring.

That matters because a health-tracking watch only collects useful information while you are wearing it.

A Display Designed for Direct Sunlight

The 1.52-inch Super AMOLED display reaches up to 5,000 nits of brightness, compared with 3,000 nits on the original Ultra.

That should make workout information easier to read outdoors, particularly while running, cycling or hiking in bright sunlight. The screen has a 498-by-498 resolution and supports a full-color always-on display.

Five thousand nits sounds excessive for something attached to your wrist, but outdoor readability is one area where additional brightness has a practical benefit.

It Is More Than a Tough-Looking Smartwatch

The Ultra 2 uses a shock-resistant titanium case and carries 10ATM, IP69K, MIL-STD-810H and EN13319 ratings.

Samsung is also positioning it as a genuine diving instrument. The watch can automatically display information such as depth, dive time and water temperature when entering the water.

For land-based adventures, its dual-frequency GPS should improve location tracking in challenging environments. Trail Run mode can track elevation, climbing progress and terrain impact, while supported routes can be loaded through Samsung Health or compatible GPX files.

Most buyers will never test the watch near its physical limits. However, this additional durability should still provide confidence during swimming, hiking, outdoor work and everyday accidents.

A Faster Processor and More Storage

The Galaxy Watch Ultra 2 uses Qualcomm’s five-core, 3nm Snapdragon Wear Elite processor, accompanied by 2GB of memory and 64GB of storage.

The additional efficiency contributes to its battery performance, while the storage provides more room for apps, offline music and other watch content.

It runs Wear OS 7 with Samsung’s One UI 9 Watch interface and works with Android phones running Android 13 or later. As expected, it is not compatible with the iPhone.

Health and Fitness Features

Samsung’s BioActive Sensor combines optical heart-rate monitoring, electrical heart-signal measurement and bioelectrical impedance analysis. The watch also includes temperature, accelerometer, barometer, gyroscope, geomagnetic and ambient-light sensors.

Its health and fitness capabilities include:

• Continuous heart-rate monitoring
• Sleep and recovery information
• Body-composition estimates
• Personalized heart-rate zones
• Running and cycling metrics
• Dual-frequency GPS tracking
• Fall detection
• An 86-decibel emergency siren
• Samsung Health integration

These features are useful indicators, but a consumer smartwatch should not replace professional medical evaluation or equipment.

What Samsung Still Didn’t Fix

The Ultra 2 retains a touchscreen-focused interface.

Samsung includes a customizable Quick Button for workouts and other actions, but there is still no physical rotating bezel or digital crown. That omission is especially noticeable on an outdoor watch, where gloves, rain, sweat and movement can make touchscreen navigation less convenient.

The other obvious drawback is price. At $699.99, the Ultra 2 is firmly positioned as a premium device. Many buyers will receive everything they need from a less expensive Galaxy Watch.

Should Original Galaxy Watch Ultra Owners Upgrade?

Probably not—unless one of the following improvements solves a genuine problem for you:

• You frequently run out of battery.
• You want professional diving features.
• The original model feels too thick.
• You need the brighter outdoor display.
• A strong trade-in promotion significantly reduces the price.

The original Ultra remains a highly capable watch. Its successor improves the formula instead of completely reinventing it.

If you own a Galaxy Watch 5, 6 or 7, the difference should be considerably more noticeable.

Accessories Worth Buying

A few carefully chosen accessories can make the Ultra 2 easier to wear and protect without turning it into an oversized piece of armor.

An additional band

A lighter fabric band can be more comfortable for sleep and everyday wear, while silicone is usually better for swimming and sweaty workouts.

Ultra-family bands use a specialized attachment system, so do not purchase an ordinary Galaxy Watch band without checking compatibility.

A screen protector

The watch is designed for outdoor use, but a screen protector is inexpensive insurance against scratches from tools, rocks, gym equipment and accidental impacts.

Look for a protector specifically listed for the Galaxy Watch Ultra 2’s 47mm display.

A charging stand

The dedicated charging puck works, but a stand creates a cleaner bedside or desk setup and makes the watch easier to place correctly.

Some stands require you to insert Samsung’s charging puck rather than including their own charger, so inspect the listing carefully.

A protective case

A case is probably unnecessary for normal daily use, given the titanium body and durability ratings. It may still make sense for construction work, climbing or other activities where the case could repeatedly strike hard surfaces.

Is the Galaxy Watch Ultra 2 Worth It?

For the right Android user, yes.

The Galaxy Watch Ultra 2 combines the convenience of a full Wear OS smartwatch with a bigger battery, highly visible display, rugged construction and serious outdoor tracking.

It is not inexpensive, subtle or small. It is also not the best value for someone who only wants notifications, step counts and occasional workouts.

But if you want Samsung’s most capable smartwatch—and particularly if battery life kept you away from the original Ultra—the Ultra 2 looks like the model worth considering.
