OnePlus Watch 2 vs Samsung Galaxy Watch 6: Hardware

Look & feel

Both the OnePlus and Samsung embrace the classic circular watch shape, so not much difference there. In terms of build materials, the OnePlus Watch 2 and Samsung Galaxy Watch 6 Classic opt for a premium feel with stainless steel cases. The Galaxy Watch 6 stands out with its Armor Aluminum construction, aiming for durability while maintaining a lightweight feel.

When it comes to size options, the OnePlus Watch 2 is available in a singular dimension, offering simplicity in choice. Samsung, however, provides more variety. The Galaxy Watch 6 available in 44mm and 40mm sizes, and the Classic version in 47mm and 43mm sizes, catering to different wrist sizes and preferences for watch face real estate.

Physical buttons offer a tactile way to interact with your smartwatch. The OnePlus Watch 2 features a rotating crown that doubles as a multi-function button. Plus there’s a flat action button below it. The Samsung Galaxy Watch 6 includes two standard push buttons for navigation. Meanwhile, the Galaxy Watch 6 Classic adds the iconic rotating bezel around the display for an additional, intuitive way to navigate the interface.

Display, colour options, water resistance

The screen technology in these watches is cutting-edge. The OnePlus Watch 2 boasts a high-res 1.43-inch AMOLED display. The Samsung Galaxy Watch 6 and Classic models feature Super AMOLED displays, with the screen size and resolution varying according to the model.

For those who enjoy water activities, all three smartwatches offer strong water resistance with 5ATM and IP68 ratings. This means they can withstand submersion in water, making them suitable for swimming and showering. No big difference there.

Finally, color options allow you to personalize your smartwatch. The OnePlus Watch 2 comes in Black Steel and Radiant Steel variations, while the Galaxy Watch 6 provides Graphite, Gold (40mm only), and Silver (44mm only) choices. The Galaxy Watch 6 Classic offers a more refined look with Black and Silver colorways.

Sensor technology

Under the hood, these watches pack the standard accelerometer, gyroscope, optical heart rate sensor, and blood oxygen monitoring (SpO2). Each device also includes a geomagnetic sensor and light sensor for ambient light adjustments, as well as a barometer to track altitude changes.

However, the Samsung Galaxy Watch 6 and Galaxy Watch 6 Classic distinguish themselves with the inclusion of a temperature sensor. This has applications in cycle tracking and more accurate sleep monitoring. Additionally, Samsung’s BioActive Sensor combines three health sensors (optical heart rate, electrical heart signal, and bioelectrical impedance analysis) for features like ECG monitoring and body composition analysis. Plus there’s the ability to track blood pressure (requiring initial calibration with a traditional cuff).

For positioning, the OnePlus Watch 2 excels with dual-frequency GPS, offering the potential for more precise location tracking. All three models support the standard GPS, Glonass, Galileo, and Beidou satellite systems.

They also come with NFC for contactless payments, and onboard storage for music so you can leave your phone behind during workouts. Here, the OnePlus Watch 2 pulls ahead again. It offers a generous 32GB of storage, double the capacity of the Samsung Galaxy Watch 6 series.

Battery life

The OnePlus Watch 2, with its innovative Dual-Engine Architecture, offers an impressive battery life. It lasts up to 100 hours in smart mode with the always-on display (AOD) turned off. For users with heavy usage, the watch can still provide up to 48 hours of service. In power saver mode, it extends its longevity to an astonishing 12 days. This remarkable battery performance is complemented by the inclusion of 7.5W VOOC Fast Charging, allowing its 500mAh battery to be fully charged in just 60 minutes, ensuring that users are always ready to go without lengthy downtime.

On the other hand, the Samsung Galaxy Watch 6 series offers up to 40 hours of battery life without the AOD function and up to 30 hours with AOD enabled. This series introduces 10W fast charging. It provides a quick boost that can deliver an additional eight hours of battery life with just an 8-minute charge, sufficient for a full night of sleep tracking. Both the Galaxy Watch 6 and Galaxy Watch 6 Classic are equipped with either 300mAh or 425mAh batteries, depending on the model size, which represents a significant upgrade from the previous generation.
