The OnePlus Watch 3 is a significant step forward for the company in the smartwatch market, building on the foundation of the OnePlus Watch 2 with a focus on refining key areas like battery life, performance, and health tracking. It represents OnePlus's commitment to creating a premium Wear OS experience that stands out from the competition.
Here is a detailed analysis of the OnePlus Watch 3's features, with a breakdown of its strengths and weaknesses.
Key Features and Specifications
Design & Build: The watch is available in two sizes: a 47mm model and a more compact 43mm version. It features a premium build with a stainless steel case and a durable titanium alloy bezel on the larger model, and a polished stainless steel case on the smaller one. It has a rotating crown with haptic feedback and a dedicated button for workouts. Both models have a sapphire crystal glass for scratch resistance.
Display: The 47mm model features a large and vibrant 1.5-inch LTPO AMOLED display with a 466x466 resolution and a peak brightness of 2200 nits, making it easily readable in direct sunlight. The 43mm model has a 1.32-inch AMOLED screen with 1000 nits of peak brightness. The LTPO technology allows for a dynamic refresh rate from 1Hz, which helps save battery life, especially with the always-on display (AOD).
Performance: The watch is powered by a unique dual-chip architecture: the Snapdragon W5 Gen 1 for smart functions and the BES2800BP MCU for low-power tasks. This "dual-engine" system, along with 2GB of RAM and 32GB of storage, ensures a smooth and responsive user experience.
Operating System: It runs on a hybrid system of Wear OS by Google (for smart features and apps) and a real-time operating system (RTOS) for basic functions and battery efficiency.
Battery Life: This is one of the OnePlus Watch 3's standout features. The 47mm model has a 648mAh battery, providing an impressive battery life of up to 5 days in "Smart Mode" with typical use, and up to 16 days in "Power Saver Mode." The 43mm model has a 354mAh battery, rated for up to 60 hours in Smart Mode. It also supports fast charging, with a 10-minute charge providing a full day of use.
Health and Fitness: The Watch 3 offers a comprehensive suite of health tracking features, including a 60-second health check-in, wrist temperature sensing, SpO2 monitoring, and continuous heart rate tracking. It also tracks advanced metrics for over 100 sports modes. A notable feature is the enhanced dual-frequency GPS (L1+L5) for improved location accuracy, even in challenging environments like cities with tall buildings.
Connectivity: It supports Bluetooth 5.2, Wi-Fi, NFC for Google Wallet, and Bluetooth calling. It is also rated IP68 for dust and water resistance and is certified with the military-grade durability standard MIL-STD-810H.
Software and Features: The watch's software, which is a mix of Wear OS and OnePlus's own customizations, offers a smooth experience with access to the Google Play Store for apps. It includes features like Google Assistant, Google Maps, and various watch faces.
Full Analysis
Best-in-Class Battery Life: The dual-chip architecture and large battery capacity are the watch's biggest assets. It offers a level of endurance that few other Wear OS smartwatches can match, making it a reliable daily companion.
Excellent Performance: The combination of the Snapdragon W5 chipset and the dual-engine system ensures a lag-free and responsive experience. App loading is fast, and navigating the interface is smooth.
Premium Design and Build: The use of high-quality materials like stainless steel, titanium, and sapphire crystal gives the Watch 3 a premium look and feel. The addition of a functional rotating crown is a welcome change that improves usability.
Comprehensive Health and Fitness Tracking: OnePlus has significantly improved its health and fitness tracking capabilities. The dual-frequency GPS, a feature usually found on more expensive sports watches, provides highly accurate location data. The new health sensors and the "60-second check-in" feature are also valuable additions.
Vibrant Display: The large, bright, and sharp AMOLED display on the 47mm model is among the best on any smartwatch, with a peak brightness that ensures excellent outdoor visibility.
Weaknesses and Considerations
No LTE Option: A significant drawback for some users is the lack of a cellular (LTE) version. This means the watch is heavily reliant on a connected smartphone for things like making calls or streaming music on the go.
Bulky Design (47mm model): While the 47mm watch has a premium look, it is quite large and heavy. The introduction of the 43mm model addresses this, but it comes with a smaller display and a lower peak brightness.
Health Tracking Accuracy: While the health tracking features are comprehensive, some reviews note that heart rate tracking accuracy, especially during high-intensity workouts, is still slightly behind top-tier competitors like Apple and Garmin.
Limited Ecosystem Integration: While it runs Wear OS and connects to Google's ecosystem, it lacks some of the deep integration that is a hallmark of the Apple Watch (for iPhone users) or the Samsung Galaxy Watch series (for Samsung phone users). For instance, the ECG feature may not be available in all regions.
Software Quirks: The hybrid OS, while excellent for battery life, can be a source of confusion. Some reviews mention that certain features are still not fully optimized to take full advantage of the dual-chip system, leading to minor inconsistencies.
Conclusion on OnePlus Watch 3
The OnePlus Watch 3 is a formidable entry into the high-end Wear OS market. It successfully tackles the single biggest complaint about most Wear OS watches: abysmal battery life. Its exceptional endurance, combined with a smooth and responsive performance, a beautiful display, and a premium build, makes it a highly compelling option for Android users.
However, the lack of an LTE version is a notable omission that might make it a non-starter for those who want a truly standalone smartwatch. While its health and fitness tracking is excellent for the average user, it might not satisfy the most data-hungry athletes.
Ultimately, the OnePlus Watch 3 is a great choice for Android users who prioritize battery life, performance, and a sleek design above all else. It's a testament to OnePlus's ability to innovate and deliver a product that is not just a competitor, but a potential leader in its class.
