The OnePlus Watch 2 marks OnePlus’s latest foray into the wearables market. Known for delivering high-quality smartphones, OnePlus aims to continue its reputation with this impressively powerful yet surprisingly long lasting smartwatch. For our review, we’re going to take a look at aspects such as design and build quality, OS software, the OHealth app usability, battery life, and a final verdict on whether it lives up to the OnePlus legacy.

OnePlus Watch 2 Nordic Blue Review | TheEffect.NetDesign & Build Quality

OnePlus has consistently prioritised design aesthetics in its products, and the OnePlus Watch 2 Nordic Blue smartwatch is no exception. It boasts a sleek, minimalist design that mixes sophistication with practicality. The Nordic Blue variant, in particular, stands out with a vibrant yet subdued hue, giving off a more premium feel.

The watch case is crafted from stainless steel, providing a sturdy but lightweight frame. The 1.43″ AMOLED display is protected by 2.5D Sapphire Crystal glass, ensuring durability against scratches and minor impacts. The display itself is bright, with a resolution of 466 x 466 pixels, offering crisp and clear visuals even under direct sunlight.

The interchangeable straps add versatility to the smartwatch, allowing users to switch between a more formal leather band and a sporty silicone option (not included in the box unfortunately.) The build quality is top-notch, with precise engineering evident in the smooth edges and overall integration of the materials. There’s no denying that the OnePlus Watch 2, and its Nordic Blue Edition in particular, is not just a gadget but a stylish accessory that compliments both casual and formal set ups.

OS Software

The OnePlus Watch 2 is quite unique in its approach to how its OS is run. Internally, the watch runs on both the latest version of Wear OS, Wear OS 4, by Google, alongside a lightweight RTOS (likely an acronym for an unspecified Real-Time Operating System, a type of OS that’s fast, but doesn’t offer as much as Wear OS in the way of features) powered by the BES2700 chip.

With this approach, which can be seen to offer the best of both worlds, the OnePlus Watch 2 offers a pretty intuitive user experience. The interface is clean and responsive, with smooth transitions between menus and apps. The integration of Google’s ecosystem is a significant advantage, providing access to a wide range of apps directly from Google’s Wear OS enabled Play Store.

The Watch 2 also supports Google Assistant, which is handy for voice commands and for setting reminders, sending messages, and controlling smart home devices. The on-screen keyboard, though small, is surprisingly accurate, making it feasible to respond to messages without needing to reach for your phone.

The performance is bolstered by the Snapdragon W5 Gen1 processor, along with 2GB RAM and 32GB ROM for Wear OS 4 and 4GB EMMC FOR the RTOS, resulting in pretty seamless multitasking without noticeable lag.

OHealth App Usability & Features

The OHealth app is the centrepiece of the OnePlus Watch 2 health and fitness tracking capabilities. Designed to be user-friendly, the app offers a comprehensive suite of features that cater to both casual users and fitness enthusiasts.

Setting up the app is straightforward, with clear instructions and a simple interface that guides users through the initial configuration. Once set up, the OHealth app tracks a wide range of metrics, including heart rate, sleep patterns, blood oxygen levels, and physical activity. The real-time heart rate monitoring is accurate, with alerts for abnormal readings, which can be crucial for those with health concerns.

The sleep tracking feature is particularly impressive, providing detailed insights into sleep stages and quality. The app offers personalised tips to improve sleep based on the collected data, promoting better health and well-being. For fitness tracking, the OHealth app supports multiple workout modes, including running, cycling, swimming, and more.

Each mode offers specific metrics and analysis, helping users optimise their workouts and track progress over time. I found the automatic exercising tracking to be pretty accurate and its ability to auto pause and restart its tracking (when you come to a set of traffic lights on a run, for example) is also really useful in making sure everything is as accurate as possible.

Additionally, the app includes stress monitoring and guided breathing exercises, which are handy when you need some downtime.

The overall usability of the OHealth app is excellent, but, on our Pixel 8 Pro which was running the app, the interface seemed slightly off and not aligned correctly for the ‘tracking circles’ at the top so hopefully this is something that’s updated in a future update.


Good battery life is a critical aspect for any modern day wearable and the OnePlus Watch 2 has a lot going for it, if you’re willing to change the way you might use a smartwatch… let me explain. When the Watch 2 launched, OnePlus spoke about its incredible battery life, thanks to its aforementioned dual OS set up.

The smartwatch is equipped with a 500mAh battery, which OnePlus claims can last up to 100 hours, or just over 4 days, on a single charge in ‘Smart Mode’. In real-world testing (or what OnePlus calls ‘Heavy Use’) it doesn’t make it that far but it’s more to do with my habits rather than the device being falsely promoted.

I like to have the always on display activated as, for me, being able to see the time anytime I glance at my watch (not actively raising my wrist or tapping the screen) the battery performance comes in around two days, which is still 100% more battery life than the Pixel Watch 2.

When making any edits to features that impact the watch’s battery life, OnePlus are pretty clear via a pop up on the screen that the battery life will be reduced. If you do decide to strip back some of the functionality and put the device into ‘Power Saver Mode’ OnePlus states an expected use time of up to 12 days which is pretty insane. I haven’t actually had the chance to test this and, being frank, I think the compromises are just that bit too much and would take away from the Watch 2 being something I’d actually benefit from wearing on a day to day basis.

All that aside, charging the smartwatch is convenient and relatively quick, thanks to the magnetic charging dock that snaps easily onto the back of the watch. A full charge takes about 60 minutes, which is pretty impressive, given the battery longevity.


The OnePlus Watch 2 is a well-rounded device that combines elegant design, robust build quality, and a comprehensive set of features. The seamless integration of both OS’s and Google’s ecosystem enhances the user experience, while the OHealth app provides valuable health and fitness tracking capabilities.
