This is one of the best WearOS watches you can get

ReviewOctober 13, 2025

The WearOS Sleeper Hit - Better Than The Big Names! They should call this watch the "WearOS Sleeper" because what you get for the money is better than any other WearOS watch I own, including my Samsung premium watches, my Pixel Watch, and even my Apple Watch Ultra 2. First, let's compare it to the Google Pixel Watch. There is no comparison. For the same price, this watch is easily twice as good. It's better built, looks way nicer, and has so many more features in terms of health tracking and screen quality. The Pixel Watch practically requires a screen protector because its screen scratches so easily. However, because the screen is curved, you're stuck using film protectors, which tend to peel up at the edges and don't protect as well as tempered glass. On this OnePlus watch, the screen is flat, which I much prefer because I can use a proper tempered glass protector. In terms of health features, this watch crushes the Pixel Watch. With the Pixel, you get basic heart rate monitoring and that’s about it. With this watch, you get EKG, blood oxygen levels, skin temperature monitoring, period tracking, vein elasticity, excellent sleep monitoring, and so much more. The Pixel Watch costs more, has terrible battery life, and frankly, looks like a low-end watch. If you are debating between this watch and the Pixel Watch, get this one. You will also prefer the oHealth app, which is free, over Fitbit, which puts many features behind a paywall. Next up is a comparison to a premium-priced watch: my Samsung Galaxy Watch. In terms of looks and comfort, the OnePlus is a better watch. My Samsung is boxy with a lot of metal surrounding the screen, making it heavier than this watch. Feature-wise, this watch has a rotating digital crown that makes navigation so much easier. The Samsung watch lacks a rotating crown, so you have to use your finger to swipe around, which leaves fingerprints all over the screen. The battery life is also far superior on the OnePlus. My Samsung will give me a solid two days, but I have gone four days with this watch, and it also charges much faster. The only thing I like better on my Samsung is the magnetic charging versus the pogo pins on this one. Also, despite the cases of the two watches being basically the same size, the screen is bigger on this OnePlus watch because the bezels are way smaller. This device looks like a classic watch; the Samsung looks like it's just copying Apple. Furthermore, many of the Samsung's best biometrics (like blood pressure and body composition) only work if you also have a Samsung phone. If you pair it with another Android phone, you lose most of those advanced features. The OnePlus has all of its features available for any Android phone, plus unique ones like vein elasticity. If you don't own a Samsung phone, the choice is easy: get the OnePlus. As for my Apple Watch, it isn't a fair comparison. I'm one of those people who carries both an iPhone for work and an Android phone for personal use. Since the Apple Watch doesn't pair with Android, a side-by-side comparison isn't really possible, but I can say that I enjoy using this watch more than my Apple Watch Ultra. Bottom line: with this watch, you are getting a rotating dial, a bigger screen, a premium build, great software, fantastic battery life with a quick charge, and full compatibility with all Android phones, packed with biometric features. I don't know how this watch isn't more popular because you would need to get into expensive Garmin territory to find something that even comes close to what this watch offers for the price.

Just buy it!!!

MaximuslarryousSeptember 27, 2025

I spent a good 4 months debating with myself if I should buy this watch or not. I watched every single YouTube review I could find. End of August I finally decided to buy one because Amazon finally had them for sale. September 1st I flew to Iceland for a 12 day vacation. It was the perfect time to see watch this battery life claim was all about. The 16 day battery in Power Saver mode. I thought no way that could be true. I'm coming from a Galaxy watch 6 classic that I had since they first got released and the battery on those things are horrible. I was charging that thing twice a day. It didn't start out quite that bad but the last 6 months was really bad. Anyway, with the Oneplus watch 3 in Power Saver mode you can track all of your workouts, including using GPS, get all your notifications, use Heart rate monitor, timers, alarm clock. Basically everything I was using on my galaxy watch. I got a total of 17 days of battery on one charge. Charged it to 100% on September 1st before flying to Iceland. Flew home on September 13th and didn't put it back on the charger until September 17th mid day. I couldn't believe it. I still can't believe it. Now I switch back and forth between Power Saver mode and Smart watch mode because contactless payments and the ability to use Gemini can only work in Smart watch mode. I still get over a week per charge. GPS tracking has been extremely consistent for me. I walk the same route every day. All open sky. No tree cover or tall buildings. I start and stop tracking at the exact same spot and so far every day has been 6.34 miles. The watch will tell you every mile you walk and how long it took to get that mile and every day each mile is at the exact same spot. Very impressive. So far I love this watch. Is it as accurate as a Garmin? Probably not. But I'm way happier with this than my Galaxy watch. Samsung, Google pixel, Apple watches can't compete with this Battery life. I no longer have battery anxiety with this watch. Read more

Glad I gave OnePlus Watch 3 a try

EricDecember 17, 2025

I like this watch a lot, lots of functions that my Garmin vívoactive 4 didn't or wasn't good at (their newer products are probably better than the older ones of course but I was ready for a change) Answering phone works well and speaker and mic are clear no complaints from either end of calls. Texting is fine too but keyboard is small, but accurately selects the key despite my big finger. Notifications come through fine too. Solidly built, I haven't dropped it but I expect it to not be effected in any way. Has nice weight to it, some people might think its heavy but is a nice feel to me. Battery life is excellent. I charge it about every 4 days. I've had a OnePlus phone before and liked it so was easier to switch brands. Read more

Great watch, great battery life!

LouieDecember 29, 2025

I have been wearing the Oneplus 3 for about one month. The band is comfortable and the watch looks classy in the silver that have. I love that the battery last at least four days in standard mode. I have not fully tested the power saving mode but it is a life saver when the battery is low. The software seems to be quick and sufficient (I am not a power user). I came from a Galaxy 4 and the only thing I may miss is having the interconnectivity of the Samsung family products. Research for yourself how long OnePlus will provide operating systems updates, I am guessing three years. Where google offer a longer support time. Price and features out weighed that con for me.

Great android watches

SergeyDecember 8, 2025

Nice looking watches which looks pretty nice on my hand which is pretty thin. The strap is surprisingly very soft and feels nice. Batter capacity is hard to beat. This watch last the same as my garmin watches, but have much more features Read more
