What you pay extra for with Xiaomi—and what you don’t
In everyday use, you won’t find a big difference between them. Both watches have, besides the main chip, an energy-saving coprocessor BES2800, 2 GB RAM, and 32 GB storage. Both have Google Play, Google Wallet, and the Gemini assistant. Both can already do EKG. Xiaomi unlocked it for the Watch 5 with an update in July 2026 and the official page lists it with European CE certification.
The displays are almost the same size—1,54 inches on Xiaomi and 1,5 inches on OnePlus. In high-brightness mode, both keep 1 500 up to 1 600 nits. OnePlus has an LTPO panel that saves battery with the always-on display enabled. As the only one of the two, it also has a thermometer.

Cheaper watches are lighter, thinner, and more durable
The OnePlus case is made of titanium, so the watch weighs 43 grams instead of 56 and is 11 mm thick. Xiaomi has a steel case and a thickness of 12.3 mm. You can feel the difference on your wrist right away, especially when sleeping. In addition to 5 ATM water resistance, OnePlus also has IP68 and IP69 ratings, plus a MIL-STD-810H military certification. Xiaomi only has 5 ATM.

The reviewer MrArchieTech also tested the cover glass. It turned out that only the OnePlus glass is true sapphire; the Xiaomi stayed just below the threshold. Xiaomi, on the other hand, has sapphire also on the underside with sensors. OnePlus charges in 60 to 75 minutes, Xiaomi in about 90 minutes. The OnePlus charger also includes a standard USB-C port instead of a permanently connected cable.

The larger Xiaomi battery didn’t show any difference in the test
On paper Xiaomi clearly wins. Watch 5 has a battery 930 mAh, while OnePlus only has 646 mAh. The difference is 44%. The manufacturers promise six days vs five. MrArchieTech, however, wore both watches at the same time with the same settings: always-on display turned on, all notifications, heart-rate monitoring every five minutes, and a daily half-hour workout with GPS. Both lasted exactly three days.
Xiaomi Watch 5
With lighter use, Xiaomi still has the edge. The editorial team at GSMArena measured five days of normal operation with health tracking. If you want to charge the watch as rarely as possible, the extra you pay for Xiaomi is worth it.
Where’s the catch with OnePlus?
The biggest catch, however, is outside the watches. OnePlus 17. in July 2026 officially announced that in Europe and North America it will no longer list new products, including watches. For devices already sold, it promises updates within the originally stated range, valid warranties, and further service. You’ll still handle the statutory warranty for this purchase with the seller. Don’t expect a successor to the Watch 4 in Europe, and long-term support is questionable.
The difference is visible during workouts. OnePlus Watch 4 don’t have interval training, split times, or routes in GPX format, and they can’t broadcast heart rate to other devices. Xiaomi can do all of that. With OnePlus notifications, the display won’t light up—only the app icon shows; Xiaomi also displays a text preview. The Watch 5 also has a voice recorder directly in the system, plus gesture control via the EMG sensor.
Both watches are made in just one size, around 47 mm. So they’re big for a slim wrist. Payments via Google Wallet depend on the bank for both, so make sure to verify support for your card in advance. And since you’re not buying OnePlus from a Slovak shop, you’ll handle returns with the seller.
If you just need standard tracking of sports activities and health, you’ll get lighter, more durable watches with OnePlus Watch 4 for less money. For training in more detail—or the longest battery life with light use—it’s worth paying extra for Xiaomi. You’ll find all twelve disciplines with heart-rate and GPS measurement in our comparison of both watches.
