Design and Build

OnePlus Watch 2 fonearena 15

The OnePlus Watch 2 has a circular dial, same as the first OnePlus Watch. However, this is heavier at 49 grams without the strap since this has a bigger battery and stainless steel case. With the strap, it is 80 grams, making it heavy compared to other smartwatches, and it might be big for thoese with small hands since it is 47mm. It looks and feels premium, but has a glossy finish, so it attracts fingerprints easily.

The smartwatch has 5ATM + IP68 water resistance, so you can even wear when swimming, and it also has MIL-STD-810H certification, making it durable.

There is Acceleration sensor, Gyroscope sensor, Optical heart rate sensor, Optical pulse oximeter sensor, Geomagnetic sensor, Light sensor and Barometer sensor. It uses Bluetooth 5.3 to connect to Android devices, and doesn’t work with iOS. It has Dual-frequency GPS L1+L5 as well has Beidou, Galileo, GLONASS, and QZSS.

Coming to the strap, it is made of skin-friendly rubber strap that is durable and sweat resistance. The 22mm straps are also interchangeable, so you can use your own straps.

There are Home and multifunction buttons on the right, with a metal finish on the right side. You can also press and hold the home button to turn on Google Assistant, press is once to wake it up and double press to launch the most recent app you opened. Pressing the multifunction button once launches the sports app, pressing it twice launches Google wallet, and press and hold lets you power on the watch / open power menu.

You can also see the tiny microphone on the back part on the left side, and the speaker is on the other side.  Since this has Bluetooth calling support, you can take calls directly from the watch when you connect it to the smartphone over Bluetooth.

On the back, there are heart rate and SpO2 sensors with glowing green and red LED lights when you are using it to measure heart rate, and SpO2, respectively. There is Made in China branding on the back along with the model number. You can also see the contact pins for charging.

The watch is powered by a Snapdragon W5 4nm processor when is used for Wear OS, and the watch also has BES 2700 power efficient chip which it is runs RTOS to handle background activity and daily tasks. It has 2GB RAM and 32GB of internal storage.

Display and features

Coming to the display, the OnePlus Watch 2 has a single model with a large 1.43-inch (466 × 466 pixels) AMOLED colour touch screen display with 2.5D Sapphire Crystal protection that you hardly see in models in the price range. I didn’t notice any scratches during my use.

You can set it to turn on when you lift your hand, and the screen turns off in a few seconds to save power.  The touch screen is smooth to use, has good viewing angles, and the outdoor visibility is good as well since it has up to 1000 nits peak brightness in high brightness mode and the default maximum brightness is 600 nits. You can adjust the brightness from level 1 till level 5, and the ambient light sensor is helpful in settings up the brightness according to the condition.

There is also an easy notification shade option when you swipe from the bottom. The quick settings come up when you swipe from the top. This has Airplane model, touch lock, find my phone, bedtime mode, DND, brightness adjustment, Bluetooth headphones, volume control, sound / vibration toggle, battery, option to switch between smart and power saver modes and settings option.

Bluetooth Calling

The built-in calling feature is good if you are calling indoors, but not the best outdoors in traffic. It shows call log, and there is even a dial pad, in addition to the contacts option which is synced from Google contacts so that you don’t have to pick the phone.

The OnePlus Watch 2 runs Wear OS 4, and it also uses RTOS, thanks to the company’s own dual engine architecture. This lets you switch between two entire wearable operating systems.

If you want to use the Wear OS apps, you can use smart mode, otherwise the power saver mode can handle background activity and daily including fitness and sleep tracking while improving the battery life.

Smart mode to power saver mode takes a few seconds to switch, but the watch restarts when it switches from power saver mode to smart mode, so it takes a couple of minutes to switch.

The Wear OS 4 brings support for watch-compatible apps on your smartphone, so they will be downloaded onto the smartwatch. Even though the smartwatch works with any Android phone, OnePlus smartphone users get synchronization of the Weather and Alarm apps between the OnePlus smartphone and OnePlus Watch.

This doesn’t have OnePlus TV connection like the first OnePlus Watch, which enabled a smart remote control that can lower volume when a call comes in or even turn off the TV before when it detects that you have fallen asleep.

The OHealth companion app has health, fitness and device tabs. These give all the important details at a glance.

The app lets you manage notifications. There are lot of workout and health settings, and enabling more features will decrease the battery life.

You can install apps such as Strava, Audible, Spotify, WhatsApp or any other Google apps such as YouTube Music, and Google Maps directly from Google Play. There is offline music playback support for both Spotify and YouTube Music to make use of 32GB internal storage. However, there is no 2x option, which I usually use when listening to podcasts. There is Google Pay wallet app, but it doesn’t work in India.

The app also lets you customize watch faces. There are 20 built-in watch faces and 80 downloadable watch faces, and you can also get more watch faces using third-party apps from Google Play. Complications offer quickly access important information at-a-glance and launch the apps you use the most.

Fitness tracking

The OnePlus Watch 2 has support for over 100 sports tracking modes. This includes running, walking, cycling, swimming, rowing machine workouts, and elliptical machine workouts.

It offers insightful recommendations based on your personal data for running and badminton mode. Steps tracking is accurate compared to data from a phone. GPS tracking is accurate compared to Strava app on a phone, and the GPS tracking doesn’t cut out if there are some intrusions like trees or bridges since has dual-band GPS. It just takes about 5 seconds to get a GPS lock.


For running, it shows a lot of data such as pace, elevation, heart rate, Vo2 Max, cadence, stride length, and even shows running power that is available only in high-end smartwatches. You can swipe to pause a workout in the middle, resume it or stop it.

OnePlus Watch 2 Badminton Tennis and Skiing modes

OnePlus says that the watch offers number of swings taken and the longest continuous rally for Badminton. The Tennis mode shows tennis-centric stats like the number of shots played, and offer details about what type of shot was played, differentiating between shots like forehand and backhand, topspin, slice, and more.

The Skiing mode offers total skiing distance, ski time, maximum speed, average speed, vertical distance, maximum slope,
and maximum altitude. For individual downhill runs, you can even track the time, distance, and maximum speed per run as you try to top your Personal Best every time, says the company.

The OHealth app doesn’t have any coaching features. You can share the workout data as an image, but there is no option to download the data and it also lacks Strava sync, but the it is expected in the future. There is Google Fit sync and support for Health Connect by Android for managing data permissions from multiple health and fitness apps and devices.

Sleep tracking is accurate and there is also data for different stages such as REM, Light and Deep sleep with a chart. It also shows average blood oxygen level. It also says the watch can detect Snoring when you place the phone near your face during sleep, but I didn’t try it. Overall, the watch has the best fitness and sleep tracking for the price.

Heart rate, SpO2 and Stress monitoring

The smartwatch uses LED lights and photo-diodes to illuminate the blood vessel for a while and monitors the heart rate via the change of green light absorbed. You can’t say this is 100% accurate, but heart rate recordings — both resting and active, are good.  It stores the data with date and time. There is also Vo2 Max data. Compared to pulse oximeter, this is almost accurate. It can also measure stress throughout the day.

Battery life

The watch has a 500mAh battery, and the company promises 100 hours or 4 days of battery life in smart mode. I have been using it for a week now, and for my heavy use with all the tracking including advanced sleep tracking enabled, notification enabled, a couple of calls, and 45 minutes of outdoor running or workouts every day, I got two and half days of battery life, which is good. With power saver mode enabled for the rest of the third day, I was able to get 3 days of battery life.

In power saver mode, it promises up to 12 days of battery life. The watch goes to hibernation mode during sleep to save the battery. Battery life might vary depending on frequent use of the display with increased brightness, use of GPS, heart rate monitor during workouts, Spo2 monitoring during sleep and all the notifications turned on.

The watch uses a proprietary charging method, but the charging dock has a removable cable, so you can use any cable. It takes about an hour to charge the watch fully using OnePlus’s VOOC charging at 7.5W, which is good. OnePlus says that a 10-min charge can offer a day’s battery life in smart mode, which is accurate, since it took about 20 minutes for 50% charge.


Overall, the OnePlus Watch 2 ticks all the boxes, and is a good successor to the first OnePlus Watch. You have a brilliant AMOLED screen, a powerful processor along with a power efficient co-processor, a lot of data for fitness activities and dual OS architecture for a long battery life without compromising the user experience.
