Samsung Galaxy Watch 8 Review (March 2026) Complete Guide & Testing Results
I spent three weeks testing the Samsung Galaxy Watch 8, and it completely changed my mind about smartwatch design.
After wearing the same round smartwatch design for years, Samsung’s new cushion-shaped case felt weird for exactly two days. Then something clicked.
The Galaxy Watch 8 costs $360 for the 44mm model I tested, which is $50 more than the Galaxy Watch 7. That price increase stings, especially when battery life remains stuck at one day.
Our testing revealed surprising strengths and frustrating weaknesses that Samsung’s marketing won’t tell you about.

Check Price on AmazonThe Galaxy Watch 8 represents Samsung’s boldest design change in years, ditching the traditional round face for a distinctive cushion shape that actually works.
Samsung packed the Exynos W1000 processor with 2GB RAM and 32GB storage into an aluminum case that weighs just 33.8 grams. The 1.47-inch AMOLED display delivers 396×396 resolution with always-on capability.
![Samsung Galaxy Watch 8 (2025) 44mm Bluetooth Smartwatch, Cushion Design, Fitness Tracker, Sleep Coaching, Running Coach, Energy Score, Heart Rate Tracking, Graphite [US Version, 2 Yr Warranty] - Customer Photo 1](https://www.ofzenandcomputing.com/wp-content/uploads/2025/09/B0F7PZNZQD_customer_1.jpg "Samsung Galaxy Watch 8 (2025) 44mm Bluetooth Smartwatch, Cushion Design, Fitness Tracker, Sleep Coaching, Running Coach, Energy Score, Heart Rate Tracking, Graphite [US Version, 2 Yr Warranty] Customer Review")
Real-world performance impressed me with instant app launches and smooth navigation through One UI 8 Watch. Google Gemini responds to voice commands in under two seconds.
The BioActive sensor tracks heart rate, body composition, and blood oxygen levels. New additions include vascular load monitoring and an antioxidant index that provides insights into oxidative stress.
Battery life remains the biggest disappointment. My 44mm model lasted 26 hours with always-on display enabled and dropped to 8% after a typical workday starting at 7am.
What Users Love: Excellent build quality, sleek design, improved UI fluidity, running coach feature, easy setup with Samsung phones, clear audio quality.
Common Concerns: Daily charging requirement, heart rate tracking issues during exercise, sleep tracking inaccuracy, awkward band attachment system, silicone band doesn’t breathe well.
What is the Samsung Galaxy Watch 8?
The Samsung Galaxy Watch 8 is Samsung’s latest smartwatch featuring a distinctive cushion-shaped case design, Google Gemini AI integration, comprehensive health tracking, and Wear OS 6 with One UI 8 Watch interface.
It’s the first major design departure from Samsung’s traditional round watch face in years.
The watch targets Android users who want premium health tracking features and AI assistance on their wrist.
Design and Build Quality: The Cushion Revolution
The Galaxy Watch 8 features a unique cushion-shaped aluminum case that measures 44.4 x 44.4 x 9.7mm, weighs 33.8 grams, and includes Samsung’s new Dynamic Lug band attachment system.
The cushion design looks strange in photos but feels natural on the wrist. After three weeks of wear, my round watches now look outdated.
Samsung used aluminum for the case instead of the stainless steel from previous Pro models. This reduces weight but scratches appeared after two weeks of normal use.
The area where the case meets the display gets grubby quickly. Daily cleaning with a microfiber cloth became necessary to maintain the premium look.
Dynamic Lug bands snap into place with a satisfying click. However, removing them requires using the included tool or a paperclip, making quick band changes impossible.
⏰ Time Saver: Keep the band removal tool on your keychain if you switch bands frequently for different activities.
The fluoroelastomer band feels soft initially but doesn’t breathe well during workouts. Sweat buildup under the band caused skin irritation after extended wear.
Water resistance reaches 30ATM plus IP68 rating, surpassing most competitors. I wore it swimming, showering, and in heavy rain without issues.
Key Features and Specifications
The Galaxy Watch 8 runs on the Exynos W1000 processor with 2GB RAM, 32GB storage, comprehensive health sensors, Google Gemini AI, and connects via Bluetooth 5.3 or optional LTE.
| Specification | Galaxy Watch 8 (44mm) | Galaxy Watch 8 (40mm) |
|---|---|---|
| Display | 1.47″ AMOLED (396×396) | 1.31″ AMOLED (432×432) |
| Processor | Exynos W1000 | Exynos W1000 |
| RAM/Storage | 2GB / 32GB | 2GB / 32GB |
| Battery | 425mAh | 300mAh |
| Weight | 33.8g | 28.8g |
| Price | $359.99 | $329.99 |
Google Gemini integration stands out as the killer feature. Ask complex questions and get intelligent responses without touching your phone.
The BioActive sensor array includes optical heart rate, electrical heart sensor, bioelectrical impedance analysis, and temperature sensor. Together they enable FDA-cleared sleep apnea detection.
Samsung added two new health metrics exclusive to the Galaxy Watch 8:
- Antioxidant Index: Measures oxidative stress levels through skin analysis
- Vascular Load: Tracks blood vessel stiffness to assess cardiovascular health
- Energy Score: Combines multiple metrics for daily wellness assessment
Real-World Performance and Daily Use
The Galaxy Watch 8 delivers smooth performance with instant app launches, responsive touch controls, and reliable connectivity, though notification wake-up sometimes lags by 1-2 seconds.
The Exynos W1000 processor handles everything I threw at it without stuttering. Apps launch instantly and scrolling through menus feels fluid.
One UI 8 Watch brings meaningful improvements over previous versions. The new tile system lets you organize widgets into folders for better organization.
Notification handling mostly works well, but the wake-up gesture fails occasionally. Sometimes I’d raise my wrist and wait two seconds for the display to activate.
⚠️ Important: Enable “Touch wake-up” in settings as backup when gesture detection fails.
Bluetooth connectivity remained stable within 30 feet of my phone. The connection dropped only when I left my phone upstairs and went to the basement.
Voice assistant response improved dramatically with Gemini. Complex queries like “What’s the weather forecast for my trip to Seattle next week?” returned accurate results.
Battery Life: The Hard Truth
The Galaxy Watch 8 delivers 24-26 hours with always-on display enabled, or up to 39 hours with AOD disabled, requiring daily charging for most users.
Samsung claims “up to 40 hours” of battery life, but real-world usage tells a different story.
My testing revealed these battery drain rates:
- Always-on display: 4% per hour during normal use
- Sleep tracking: 20% overnight (8 hours)
- GPS workout: 5% per 30 minutes
- Continuous heart rate: Additional 10% daily drain
Starting at 7am with 100% charge, the watch hit 8% by 2pm with moderate use. This included checking notifications, two 30-minute workouts, and occasional Gemini queries.
“Disabling frequent sync improved my battery life by 33% without losing any important features.”
– Samsung Community Forum member
Charging takes 75 minutes from 0-100% using the included magnetic charger. The watch reaches 45% in 30 minutes, enough for half a day’s use.
Battery optimization tips that actually work:
- Disable frequent sync: Settings > Connections > Sync frequency
- Turn off always-on display: Saves 30% battery daily
- Reduce screen timeout: Set to 15 seconds
- Disable unused health features: Turn off continuous stress monitoring
- Use power saving mode: Extends battery by 8-10 hours
Health and Fitness Tracking Features
The Galaxy Watch 8 offers comprehensive health tracking including FDA-cleared sleep apnea detection, running coach, body composition analysis, and new metrics like antioxidant index, though accuracy varies during high-intensity exercise.
Sleep tracking proved inconsistent during testing. The watch correctly identified when I fell asleep 4 out of 7 nights but often mistook TV watching for sleep.
The new sleep apnea detection requires Samsung Health Monitor app and works only with Samsung phones. It detected potential breathing irregularities on two nights, prompting a doctor consultation.
Heart rate monitoring works well at rest but struggles during exercise. Compared to a Polar chest strap, the Watch 8 showed 10-15 BPM variations during interval training.
Running Coach deserves special praise. Real-time pace and form feedback helped me maintain consistent splits during 5K training runs.
✅ Pro Tip: Wear the watch one finger-width above your wrist bone and tighten the band during workouts for accurate heart rate readings.
Body composition analysis provides body fat percentage, skeletal muscle mass, and BMI. Results matched my smart scale within 2% variance.
The antioxidant index feature requires placing your finger on the sensor for 90 seconds. Results varied significantly based on time of day and hydration levels.
Software and User Interface
The Galaxy Watch 8 runs Wear OS 6 with Samsung’s One UI 8 Watch interface, offering improved customization, Google app integration, and a refined user experience that requires initial setup patience.
Setup takes 20-30 minutes and requires three different apps: Galaxy Wearable, Samsung Health, and Samsung Health Monitor. Each app handles different features, creating confusion.
One UI 8 Watch brings welcome improvements. The new grid view for apps makes finding what you need faster than scrolling through a list.
Customization options impress with thousands of watch faces available. You can modify complications, colors, and styles to match any outfit or mood.
Google app integration works seamlessly. Maps provides turn-by-turn navigation on your wrist, while YouTube Music streams over LTE without your phone.
Software bugs appeared occasionally. Auto-workout detection paused randomly during runs, and notification syncing sometimes delayed by several minutes.
Galaxy Watch 8 vs The Competition
The Galaxy Watch 8 offers better health features than Apple Watch for Android users but falls short on battery life compared to Garmin, while matching Pixel Watch 3 capabilities at a similar price point.
| Feature | Galaxy Watch 8 | Apple Watch S10 | Pixel Watch 3 |
|---|---|---|---|
| Price | $360 | $399 | $350 |
| Battery Life | 26 hours | 18 hours | 24 hours |
| Health Features | Excellent | Excellent | Good |
| AI Assistant | Google Gemini | Siri | Google Assistant |
| Ecosystem | Android/Samsung | Apple only | Android |
Compared to Galaxy Watch 7, the Watch 8 brings design changes and AI features but keeps the same battery capacity. The $50 premium feels steep for incremental improvements.
Against Apple Watch Series 10, the Galaxy Watch 8 wins on battery life and price but loses on ecosystem integration for iPhone users.
Should You Buy the Galaxy Watch 8?
Buy the Galaxy Watch 8 if you own a Samsung phone, value design and health features over battery life, and don’t mind daily charging. Skip it if you need multi-day battery or use an iPhone.
Who should buy the Galaxy Watch 8:
- Samsung Galaxy phone owners wanting seamless integration
- Users prioritizing comprehensive health tracking
- Anyone wanting Google Gemini AI on their wrist
- Design-conscious buyers who like the cushion aesthetic
- Current Galaxy Watch 5 or older owners ready to upgrade
Who should skip the Galaxy Watch 8:
- Users needing multi-day battery life
- iPhone owners (limited functionality)
- Galaxy Watch 7 owners (minimal upgrade value)
- Budget-conscious buyers (Watch 7 offers better value)
- Athletes needing precise heart rate during intense exercise
Size recommendations: Choose 44mm if your wrist measures over 140mm or you prefer larger displays. The 40mm fits wrists 130-140mm better and suits those wanting a lighter watch.
Consider the Galaxy Watch 8 Classic if you miss the rotating bezel and don’t mind paying $110 extra for premium materials and slightly better battery life.
Frequently Asked Questions
Is the Galaxy Watch 8 worth upgrading from Watch 7?
The Galaxy Watch 8 offers minimal improvements over the Watch 7 beyond the new design and AI features. Unless you specifically want the cushion design or Google Gemini, save your money and stick with the Watch 7.
What’s the difference between Galaxy Watch 8 and Watch 8 Classic?
The Classic model adds a physical rotating bezel, uses premium materials like stainless steel, costs $110 more, and offers slightly better battery life. The regular Watch 8 has a touch bezel and aluminum construction.
How long does Galaxy Watch 8 battery actually last?

Does Galaxy Watch 8 work with iPhone?
No, the Galaxy Watch 8 requires an Android phone running Android 11 or higher. It won’t pair with iPhones and Samsung has no plans to add iOS compatibility.
What are the new health features in Galaxy Watch 8?
New health features include FDA-cleared sleep apnea detection, antioxidant index monitoring, vascular load tracking, and enhanced Energy Score with Galaxy AI insights for personalized wellness recommendations.
Should I get the 40mm or 44mm Galaxy Watch 8?
Choose 44mm for better battery life (425mAh vs 300mAh), larger display, and if your wrist measures over 140mm. Pick 40mm for lighter weight, lower price ($30 less), and if you have smaller wrists under 140mm.

Final Verdict: Beautiful Design Can’t Fix Battery Life
After three weeks with the Galaxy Watch 8, I’m torn between loving the design and hating the daily charging routine.
The cushion case grows on you quickly, and the comprehensive health tracking rivals any smartwatch available. Google Gemini integration feels like having a personal assistant on your wrist.
But that one-day battery life remains inexcusable at this price point. Garmin watches last a week, and even the Apple Watch Ultra pushes three days.
For Samsung phone owners who charge devices nightly anyway, the Galaxy Watch 8 delivers an excellent smartwatch experience. The $360 price feels fair considering the features and build quality.
Everyone else should wait for the Galaxy Watch 9 or grab a discounted Galaxy Watch 7 that offers 90% of the experience for $50 less.
