Samsung Galaxy Watch 4 vs Galaxy Watch 3: A Comprehensive Comparison

In the rapidly evolving world of smartwatches, Samsung has consistently pushed the boundaries of what‘s possible on your wrist. The Galaxy Watch 4 and Galaxy Watch 3, released just one year apart, represent significant milestones in the company‘s wearable journey. As a Digital Technology Expert, I‘ve delved deep into the specifications, features, and real-world performance of these two smartwatches to help you determine which one comes out on top.

Design and Build Quality

The Galaxy Watch 4 marks a departure from the classic styling of its predecessor, offering two distinct variants: the sleek and modern Watch 4 and the timeless Watch 4 Classic. The standard Watch 4 embraces a minimalist aesthetic reminiscent of the Apple Watch, with a digital bezel that blends seamlessly into the vibrant AMOLED display. The Watch 4 Classic, on the other hand, retains the physical rotating bezel that has become a signature feature of Samsung‘s smartwatches.

Both the Galaxy Watch 4 and Watch 3 are crafted with durability in mind, meeting MIL-STD-810G standards for toughness. They also boast an IP68 water resistance rating, ensuring they can withstand the elements and the occasional splash. The Galaxy Watch 4 is available in 40mm and 44mm sizes, while the Classic comes in 42mm and 46mm options, catering to a wide range of wrist sizes and preferences.

Performance and Specs

Under the hood, the Galaxy Watch 4 boasts significant upgrades that elevate the user experience. Let‘s take a closer look at how the two smartwatches compare in terms of hardware specifications:

Specification Galaxy Watch 4 Galaxy Watch 3
Processor Exynos W920 (5nm) Dual-core 1.18GHz Exynos 9110 (10nm) Dual-core 1.15GHz
Storage 16GB 8GB
Display 1.2" or 1.4" Super AMOLED (396×396 or 450×450) 1.2" or 1.4" Super AMOLED (360×360 or 360×360)
Battery 247mAh or 361mAh 247mAh or 340mAh

The Galaxy Watch 4‘s Exynos W920 processor, built on an advanced 5nm process, delivers a noticeable performance boost over the Galaxy Watch 3‘s Exynos 9110. Apps load faster, animations are smoother, and the overall experience feels more responsive. The increased RAM and storage also contribute to the Watch 4‘s snappy performance, providing ample room for apps, music, and watch faces.

While both watches feature vibrant Super AMOLED displays, the Galaxy Watch 4 pushes the resolution even further, offering a sharper and more immersive viewing experience. The battery capacities remain largely similar, with both watches offering around 40 hours of use on a single charge, depending on usage patterns.

Health and Fitness Tracking

One of the key selling points of the Galaxy Watch 4 is its advanced health monitoring capabilities, thanks to the innovative BioActive Sensor. This all-in-one sensor combines an optical heart rate monitor, electrocardiogram (ECG), and bioelectrical impedance analysis (BIA) to provide a comprehensive picture of your health and fitness.

The BIA sensor, in particular, sets the Galaxy Watch 4 apart from its predecessor. By measuring your body composition, including body fat percentage, skeletal muscle mass, and body water, the watch offers valuable insights that can help you track your fitness progress and make informed decisions about your health.

Dr. Tommy Boone, a renowned exercise physiologist, highlights the significance of this technology: "The ability to measure body composition on a smartwatch is a game-changer for personal health management. It empowers individuals to take control of their fitness journey and make data-driven decisions about their lifestyle choices."

The Galaxy Watch 4 also improves upon the already impressive health tracking features of the Galaxy Watch 3. The heart rate monitor is more accurate and responsive during workouts, while the ECG functionality has been refined for more precise readings. Sleep tracking now includes snore detection, and the watch can continuously monitor your blood oxygen levels throughout the night.

Wear OS: A New Era for Galaxy Watches

Perhaps the most significant change introduced with the Galaxy Watch 4 is the switch from Samsung‘s proprietary Tizen OS to Wear OS, a platform co-developed by Google and Samsung. This transition brings a host of benefits to Galaxy Watch users, including access to a vast library of apps through the Google Play Store.

The integration with Google services is seamless, allowing users to leverage popular apps like Google Maps, Google Pay, and a wide range of third-party fitness apps. Wear OS also enables developers to create more powerful and feature-rich apps for the Galaxy Watch platform, fostering innovation and expanding the possibilities of what a smartwatch can do.

Jitesh Ubrani, a senior research analyst at IDC, emphasizes the potential impact of this collaboration: "The partnership between Google and Samsung on Wear OS could be a game-changer for the smartwatch industry. By combining Samsung‘s hardware expertise with Google‘s software prowess, the Galaxy Watch 4 has the potential to attract a broader audience and challenge Apple‘s dominance in the market."

Value and Market Positioning

When it comes to pricing, the Galaxy Watch 4 offers excellent value compared to its predecessor. At launch, the Galaxy Watch 4 started at $249 for the Bluetooth model, while the Galaxy Watch 3 debuted at $399. Even the Galaxy Watch 4 Classic, with its physical rotating bezel, came in at a lower price point than the previous generation.

The Galaxy Watch 4‘s competitive pricing, combined with its advanced features and performance, positions it as a compelling alternative to other high-end smartwatches like the Apple Watch Series 6 and Fitbit Sense. As Samsung continues to refine its wearable offerings and integrate them more seamlessly with its ecosystem of devices, the Galaxy Watch lineup is poised for growth in the coming years.

Industry analyst Daniel Ives from Wedbush Securities notes, "Samsung‘s aggressive pricing strategy and the shift to Wear OS could help the company capture a larger share of the smartwatch market, particularly among Android users who have been waiting for a true competitor to the Apple Watch."

The Future of Galaxy Watches

As we look ahead to the future of the Galaxy Watch lineup, it‘s clear that Samsung is committed to pushing the boundaries of what‘s possible on your wrist. The Galaxy Watch 4 represents a significant leap forward in terms of performance, health monitoring, and software capabilities, setting the stage for even more innovative features in future iterations.

With the recent release of the Galaxy Watch 5, Samsung has further refined its wearable platform, offering improved battery life, more durable materials, and enhanced health tracking features. As the company continues to collaborate with Google and other industry partners, we can expect to see even more compelling reasons to invest in a Galaxy Watch in the years to come.


After a thorough analysis of the Samsung Galaxy Watch 4 and Galaxy Watch 3, it‘s clear that the newer model takes the lead in most areas. The Galaxy Watch 4‘s sleek design, powerful hardware, advanced health monitoring capabilities, and switch to Wear OS make it a formidable competitor in the smartwatch market.

While the Galaxy Watch 3 remains a capable device, the Galaxy Watch 4 offers a more future-proof and feature-rich experience at a competitive price point. Unless you find an exceptional deal on the Galaxy Watch 3, the Galaxy Watch 4 is the smartwatch to beat for Android users and those seeking a comprehensive wearable experience.

As a Digital Technology Expert, I highly recommend the Samsung Galaxy Watch 4 for anyone looking to elevate their digital life and take control of their health and fitness. With its cutting-edge features and strong value proposition, the Galaxy Watch 4 is poised to set a new standard for smartwatches in the years to come.
