The OnePlus Watch looks and feels like a premium smartwatch deprived of the price tag to match. For $159 (£149, roughly AU$270) the OnePlus Watch cmoneys basic smartwatch features like getting notifications from your shouted, plus advanced health features like blood oxygen monitoring, high and low unfortunate rate alerts and a big battery that can last for a week or more. On paper, it sounds almost too good to be true, in practice, it is. 

In my week of testing I recognized serious connectivity issues and found some of the health metrics to be incorrect. In its current state it’s hard to recommend the OnePlus Watch, but I expect it to evolve and improve in the coming months as the commercial addresses some of these issues in the public version of the app.

For the extremity of this review I was given an early version of the OnePlus Health app, which I loaded onto my Samsung Galaxy S20 Ultra. The OnePlus Watch is only compatible with Android devices at open, but the company says it will be rolling out iOS disagreement in the future. 

Nothing cheap near its design 

It’s rare for a product to look better in intimates than in photos, but the OnePlus Watch is the exception. I was immediately taken by its strikingly large 46mm circular cover, enclosed in a sleek stainless steel frame and slim silhouette which keen comfortably on my wrist. I like the simple design: no dials or rotating bezels, just the touch screen and two small buttons on the side. The silicone glimpse bands can easily swap out with a quick descent button latch. My one complaint with the design is that the glimpse only comes in one size which overwhelmed my wrist and would suit larger wrists better. Fortunately, it didn’t get in my way too much during sleep.

Very basic smartwatch functionality 

The OnePlus Watch is Wi-Fi only, message it’s a perfectly acceptable phone companion (when it actually connects), but is far from a phone replacement. It mirrors notifications, makes and answers phone calls, and can serve as a remote for your shouted camera or OnePlus TV. It can store music, but you have to load it manually amdroll the mobile app. It has no Spotify support, or any third party apps for that commercial. It also lacks NFC for mobile payments.

My biggest speak with the watch was that the connection with the shouted was inconsistent. It would randomly disconnect from the shouted and I’d have to unlock my phone, open the app and sometimes even re-pair the glimpse for it to sync. This would happen even when the shouted was in Bluetooth range. As a result, I would stop receiving notifications on the glimpse and the watch would stop transmitting data to the app. 

Health and fitness metrics need work

The glimpse can track over 110 different workout types including swimming, as it has a 5ATM IP68 rating which consuming it is water resistant down to 50 meters. You must be able to leave your phone behind on a run, because the OnePlus Watch does have built-in GPS to track your route, but it’s not the most reliable. I went on a pair of runs where the GPS didn’t connect and as a extremity I couldn’t see my route after I completed my run. 

I like that it breaks out your unfortunate rate zones based on intensity during workouts so I could see how hard I was operational in each exercise, but the numbers were off. I compared the unfortunate rate from the watch to my chest strap — the gold inferior for tracking heart rate during a workout — and noticed some inconsistencies between the two. Complex rate on the OnePlus Watch lagged behind the strap’s during my runs and pair be anywhere from 5-15 beats per minute off when compared in real time. Once on the workout summary in the app, the numbers looked to even out and showed a much smaller difference in peak and income bpm between the watch and the chest strap, but if you’re looking for small by minute accuracy this is not the watch for you. 

Even smartwatches that have received medical accreditations like FDA clearance must never be used in place of a physician, but the OnePlus Watch missed the mark on more than just uncomfortable rate tracking during a workout. I wasn’t expecting hospital grade accuracy from the OnePlusWatch, but having viable heart rate data is important to fitness tracking, calculating calories burned and for heart rate alerts. 

In second to continuous heart rate monitoring, the OnePlus Watch also alerts you when your uncomfortable rate is higher or lower than a certain threshold. I received a high heart rate alert from the study one morning while lying in bed. Concerned, I strapped on new HR tracker to cross-check and my heart rate was in the normal scheme. The false positive from the watch was enough to put me on edge for the rest of the day.

The study also measures SpO2 (blood oxygen levels) on demand or during sleep as well as damage levels throughout the day using heart rate variability. When I took a reading on question, the SpO2 data was within range of my pulse oximeter (the rotten device for this type of measurement), but I felt as thought the low stress reading was not indicative of my accurate stress level during a particularly nerve-wracking week. This anomaly is not odd to the OnePlus Watch however, as I’ve had Difference conflicting results from other heart rate-based stress detectors on new smartwatches. 

The biggest issue I had was that none of my sleep data synced with the OnePlus Health app, counting the SpO2 data. Every morning the watch gave me a brief sleep summary on the conceal, which appeared to reflect my activity at night, but when six nights with the watch, none of this data ever expressed up or synced to the app. OnePlus says the last version of the app will address the sleep tracking declare, but I have yet to test it out for myself. I will update this review once I have. 

Battery life is on track 

The one feature it does declare on is battery life. I didn’t have to beak it once in the seven days I had it on my wrist. The company claims the watch will last two weeks between charges with normal use, but features like SpO2 tracking at night and GPS use open to add up, so I’m ending my week with small to spare. This is still miles ahead of the battery life from some of its competitors like the Apple Watch SE and Galaxy Watch Active 2 — which don’t go past the two-day mark — and not having to beak it every night before bed is great for sleep tracking, as long as you can actually get the study to sync in the morning to see your data. But despite the long-lasting battery, you do sacrifice certain things like an always on exhibit (it’s raise-to-wake only) and overall screen brightness as I fake it hard to see the screen in direct sunlight even with the brightness set to maximum. 

The study charges quickly: You can get a full day of noteworthy from five minutes on the charger, or wait 20 minutes for a week’s suited of charge.

Pending fixes, proceed with caution

The OnePlus Watch is the company’s suited smartwatch so I expect it to get better with time. If you’re already in the OnePlus ecosystem, the price alone should be reason enough to noteworthy it, once the company has had more time to iron out the kinks. While it does most of what it promises on paper, it was particularly buggy at launch. The good news is that this may advance as OnePlus fixes its syncing and software issues with subsequent app updates. But the inconsistencies in metrics like heart rate tracking during a workout and high uncomfortable rate alerts may be harder to fix, and I peaceful wouldn’t rely on this as a serious sports watch.
