Display: A Window to Your World

An Always-On Display (AOD) mode offers quick glances, though it impacts battery life. AMOLED technology provides vibrant colors and deep blacks.

Performance & Software: Powering Your Day

Powered by Samsung’s 3nm Exynos W1000 SoC (penta-core 1.6GHz/1.5GHz) and 2GB RAM, the Galaxy Watch Ultra (2025) delivers a fluid user experience. It ships with Wear OS 6-based One UI 8 Watch, with Samsung promising four major OS updates.

One UI 8 Watch enhancements:

• Now Bar: Displays ongoing tasks for quick access.
• Double Pinch Gesture: Customizable hands-free control (e.g., scrolling, music, calls).
• Bedtime Guidance: Galaxy AI analyzes sleep for optimal routines.
• Running Coach: Personalized running plans (up to 160 variations) after a test run.
• Google Gemini Integration: On-wrist AI for complex tasks, email summaries, and health inquiries via voice.

Doubled 64GB internal storage (50GB available) allows more apps, offline music, and extensive GPX data for navigation, enhancing outdoor utility.

Health & Fitness Tracking: Your Personal Wellness Hub

The Galaxy Watch Ultra (2025) features Samsung’s BioActive Sensor for advanced health monitoring: heart rate, SpO2, blood pressure, skin temperature, body composition (BIA), and ECG.

Advanced metrics (many AI-powered):

• Antioxidant Index: Evaluates skin antioxidant buildup.

• AGEs Index Tracking: Monitors Advanced Glycation End Products for metabolic health.
• Sleep Apnea Detection: FDA-approved feature detects moderate to severe obstructive sleep apnea over two nights.

For fitness, it supports personalized heart rate zones for running and FTP calculation for cycling. GPX data enables guided navigation and “Track Back.” Safety features include an 86-decibel siren, SOS, fall detection, and emergency medical access. Note: ECG and blood pressure features require a Samsung Galaxy smartphone in supported regions.

Connectivity & Communication: Stay Connected

The Galaxy Watch Ultra (2025) offers Bluetooth 5.3, Wi-Fi, and NFC for payments. The 47mm model is LTE-exclusive, enabling standalone calls, music streaming, and connectivity without a phone.

Dual-frequency GPS (L1+L5) aims for pinpoint accuracy, but real-world results vary; some users report inconsistencies, especially in urban areas. Call quality is generally good, with clear microphone audio and a loud speaker, making it a viable standalone communication device.

Battery Life: Endurance for Days (or More?)

With a 590mAh battery, the Galaxy Watch Ultra (2025) offers up to 60 hours with AOD, 80 hours without, and 100 hours in Power Saving Mode. Outdoor workouts with GPS can last 48 hours.

Users generally achieve 2-3 days of battery life with typical use (AOD off). Frequent cellular calls reduce this to 1.5-2 days. Power Saving Mode can extend it further. 10W fast wireless charging allows quick top-ups.

The premium Galaxy Watch Ultra (2025) (LTE, 47 mm) retails for $649.99 (US), €699 (Europe), and $879.99 (Canada). It’s available only as an LTE variant (no Wi-Fi-only option).
