OnePlus Watch Lite review: I’m a fan of this fitness-friendly wearable’s simpler approach

Introduction

It looks the part, with a slender body and circular screen, but don’t let the name fool you: the OnePlus Watch Lite is less a smartwatch and more a watch-shaped fitness band. The firm has also started from scratch, rather than just strip the top-tier OnePlus Watch 3 back to basics, in order to boost battery life and widen wearers’ connectivity options.

WearOS is out in favour of a home-grown operating system that handles health tracking and phone notifications, and will (eventually) play nicely with multiple phones – including ones made by Apple. At £179/€179 in the UK and Europe (there’s no US launch planned) it also massively undercuts true smartwatch alternatives.

That’s still double what a CMF Watch 3 Pro will set you back, though. Has OnePlus supplied enough smarts – and perfected the design – to earn a spot on your wrist?

Design & build: does what it says on the tin

If the OnePlus Watch 3 was all about wrist presence with its large 47mm case and distinctive titanium outer bezel, the Watch Lite leans a lot more subtle. It’s smaller, coming in a single 44mm case size, and its stainless steel casing is barely visible around the edge of the circular screen. The rear panel is plastic, but doesn’t feel at all cheap – and can’t really be seen while being worn.

The Watch lite sits low on the wrist, being a scant 8.9mm thick, so easily slips underneath shirt sleeves, and it’s fairly light – without feeling hollow or giving the impression of being made to a budget. I appreciate the IP68 and 5ATM ratings, which make it the obvious choice over the cheaper CMF Watch 3 Pro if you’re a regular at your local swimming pool.

There’s just the one button at the side, though it looks like two: the digital crown up top rotates to scroll through menus, while lower town is a touch-sensitive surface used exclusively for health monitoring.

You can get one in silver or black stainless steel, with white or black rubber straps respectively. The bands are a standard size and use quick release pins for easily swapping to third-party alternatives.

Screen: punching up

Marginally thicker black border aside, there’s nothing about the Watch Lite’s display that screams “affordable territory”. The 1.46in circular AMOLED is practically as high-res as the pricier Watch 3, and is protected by the same grade of sapphire crystal glass. The way the edges curve ever-so-slightly into the watch body is very satisfying.

Colours are vivid and blacks are all but perfect, which really helps some of the more dynamic full-screen watch faces stand out on your wrist. Pick the right one and the bezel all but vanishes into the design. Viewing angles are excellent, too. I like how much information OnePlus is able to squeeze onscreen at once,

OnePlus reckons the panel can hit a peak 3000 nits brightness, which is on par with more expensive rivals like the Samsung Galaxy Watch 8. It certainly shines strongly enough that I was always able to read the watch clearly while outdoors, even on the brightest of days. There’s absolutely nothing to complain about here.

Interface: a familiar face

On first glance the OnePlus Watch Lite’s interface doesn’t seem all that different from the Watch 3’s. Icons, fonts and the general layout have all been carried over, putting it somewhere between the Pixel Watch 4‘s stripped back approach and Samsung’s in-yer-face Galaxy Watch 8.

The OxygenOS Watch UI puts quick settings and notifications a vertical swipe away from the main watch face, but the only widgets you’ll find to the right of it are health-related. A left swipe reveals a stack of cards for things like weather, calendar appointments, quick app shortcuts and music controls. The latter is just for playing tunes through your phone, with no way to store files on the watch itself; its built-in mic and speaker are for taking or receiving phone calls, and barking out lap times during exercise.

Pressing in the digital crown then reveals the full app list, although there’s not much more here worth mentioning. The shutter button for remotely controlling your phone’s camera could be handy; I’m less convinced by the short video controller for swiping through YouTube shorts or TikTok clips, and the ‘torch’ that just lights the screen up white. It barely illuminated a foot in front of my face while rooting through the cupboard under my stairs. There’s also a virtual wallet, but only for storing keys for NFC-enabled smart locks. There’s no way to use the Watch Lite for contactless payments.

As the software is OnePlus’ own creation, there’s no app store like you’ll find on a WearOS watch. Other than some typical timer and alarm functions, a compass and a barometer, the app selection is entirely health-focused.

The main benefit of going it alone, other than to battery life? The OnePlus Watch Lite will be able to connect to more than one phone at once, including iOS handsets, for incoming calls and notifications. That’s a big win if you have separate work and personal phones, and could make it a real alternative to the Apple Watch SE 3 if you split your time between Android and iOS – although support won’t officially arrive until a later, undisclosed date. My review unit showed an option to use it, but I couldn’t get it to connect to a Pixel 10 Pro as a secondary handset.

Health & fitness: the main event

The OHealth phone companion app is absolutely jammed full of watch face options, with a mix of digital, analogue, and fitness-focused styles. This is also where you’ll head to get a more in-depth look at all the health and workout metrics the Watch Lite records.

There are plenty of ’em, with the sensor suite recording heart rate, blood oxygen, wrist temperature, stress levels and cycle tracking, as well as steps and sleep stages. A 60-second health check monitors a bunch of these all at once, as well as your vascular age and whether there are any signs of arterial stiffness; you just place a finger on the side mounted sensor and sit still for a minute. It’s much slicker than bouncing between a bunch of apps to get an overview of your health.

It can record over 100 different sports and activities, with the dual-band GPS usually needing under ten seconds to get a signal lock. Route mapping was on point for the most part, though my leafy bit of suburbia wasn’t as tough a test as a city with lots of tall buildings. The optical heart rate sensor was largely reliable too, being within a few beats per minute of a more accurate chest strap HRM.

There’s a decent amount of data to peruse through after each workout, but you aren’t given any insights or coaching advice, leaving you to interpret the numbers and graphs yourself. Sleep tracking data is also pretty basic compared to something like Garmin or Whoop. Serious athletes will be left wanting, but more casual exercisers looking to get more of an overview will be right at home here.

Battery life: long lasting

The Watch Lite delivers impressive longevity, despite its 330mAh battery not being especially large compared to more fully-featured smartwatches. Running a custom operating system rather than WearOS clearly helps, as do the less demanding internals.

I managed to last around four days on average with the always-on screen enabled. That included around an hour of exercise per day, 24/7 heart rate tracking, and a regular stream of notifications from my paired smartphone. A CMF Watch 3 Pro will last a little longer, but there’s not much in it. It doesn’t need two separate chipsets like the OnePlus Watch 3 to achieve this lifespan, either.

It nudges closer to a full week with the AOD turned off, and can even reach ten days with the power saver mode, though that does disable a lot of what makes it worth wearing for health tracking.

Charging is largely painless, with a ten minute visit to the proprietary puck being good enough for a full day of wear. A full refuel takes around an hour and a half.

OnePlus Watch Lite verdict

If you’re sick of smartwatches that overdose on features, the OnePlus Watch Lite will be a breath of fresh air. It isn’t trying to be a second smartphone you wear on our wrist: aside from a few essentials, it focuses mainly on fitness, while keeping the watch-like form factor. It does a convincing impression of a pricier timepiece, and the screen is a stunner.

The health tracking could do more to guide workouts and explain the various metrics to non-athletes, and the lack of contactless payment support might be a turnoff for some. But skipping WearOS has helped give battery life a welcome boost over affordable smartwatch alternatives like the Samsung Galaxy Watch FE. Factor in the waterproof build and it’s a worthy all-weather wearable for the money.
