The OnePlus Watch 2 is now available on Amazon for $250, which is $50 less than its usual price. Because of this, it is among the greatest and easiest smartwatches we have tried.

In 2021, OnePlus released the OnePlus Watch, and I ordered it right away because the hardware looked amazing and it cost $159. I sent the item back after a few weeks because it did not provide anything useful.

Since many smartwatches operate lean and mean, the Real-Time Operating System (RTOS) used by the original OnePlus Watch was ideal. With a dual-engine design, the OnePlus Watch 2 this year goes one step further by providing both Wear OS 4 and RTOS on a single watch. The gadget has a longer battery life than any other Google Wear OS or Apple Watch thanks to its innovative design, making it the most effective Wear OS watch on the market right now.

OnePlus has produced one of the most stylish smartwatches on the market right now, in addition to a strong operating system strategy. The watch features a 2.5D smooth sapphire crystal face, a sturdy silicone band, and a stainless steel watch case. With an oval button on the bottom and a round button on top, the buttons on the right are elegantly integrated into the bezel.

With its IP68 rating and 5 ATM water resistance, the OnePlus Watch 2 is safe to wear when swimming and engaging in other outdoor activities. Furthermore, the device surpasses even the Apple Watch Ultra 2 and Galaxy Watch 5 Pro because it was constructed to meet MIL-STD-810H specifications.

According to OnePlus, the watch may last up to 12 days in power-saver mode, 100 hours in Smart Mode, and 48 hours when used extensively. Its battery is 500 mAh. I was able to charge the watch every three to four days and wear it around the clock during my two weeks of testing. I used the gadget for active heart-rate monitoring while indoor rowing, GPS tracking while running and walking, and more.

The always-on display mode will use up the battery more quickly. However, when I first tested it, I left the always-on display off because I discovered that the lift-to-wake feature worked great.

The OnePlus Watch 2 boasts a great battery life, but it also supports 7.5W VOOC fast charging, which allows you to charge it to 100% in just one hour and wear it for a day much faster. Fast charging, CPU efficiency, and a long battery life are the ideal combinations for a smartwatch.

Both L5 and L1 satellite positions are available, and Beidou, GPS, Galileo, GLONASS, and QZSS GNSS are supported. The tracking of the watch was nearly identical to that of my specialized GPS sports watches. Additionally, Wear OS support allows you to utilize your favorite watch apps instead of OHealth. The watch’s heart-rate tracking was precise as well.

The OnePlus watch does not function with an Apple iPhone, and you must have the OHealth software installed on your Android phone. The OHealth app is used to control the watch apps and settings, as well as the health and wellness functions, thus the Wear OS app is not used.

I find the OHealth app to have a more user-friendly UI than the Fitbit and Google applications that come with Pixel Watches. OnePlus has stated publicly that it has intentions to offer syncing to other services, like Strava, in the future, but for now, the data gathered by the OnePlus Watch 2 is still in OHealth.

You can measure your heart rate, blood oxygen, stress, sleep, workouts, and more with the OHealth app and OnePlus Watch 2. The Wear OS tiles that show up when you swipe left and right on the watch face may also be managed through the OHealth app. I found the OHealth app to be more user-friendly than the Wear OS app on a Pixel phone, and it has a lot of settings.

Check out the many workout and health options, such as heart-rate alerts, breathing tests while you sleep, auto-workout detection, and even the ability to customize the screens for your preferred routines.

There is potential for development even if the OnePlus Watch 2 is a far better watch than the original model. The watch lacks cellular connectivity, has a single 47mm diameter and weighs 80 grams, is not the best for people with smaller wrists, does not support fall detection, can not control a OnePlus phone camera from the watch (though this will be fixed in a future update), does not have any features for tracking women’s health, can not record ECG readings, and does not have a skin-temperature sensor.

But I really enjoyed wearing this classy watch and used the face swipe to access my favorite tiles. I can not use the Google Pixel Watch since it is very small and has a limited battery life. Better solutions at affordable prices are possible, as demonstrated by the OnePlus Watch 2.
