OPPO Watch X2 Mini, analysis

Wear OS left behind the obligation to charge watches every day with the enormous step forward that the OnePlus Watch 2. I was able to analyze it and was surprised by its duality: dual processor and dual operating system. OnePlus has promoted this innovation, so has OPPO. The Watch X2 Mini that I have tested is a worthy heir.

Very compact, loaded with features despite being contained, with five days of autonomy and good performance in the sports record. At least for a smartwatch that is not specifically geared toward workouts. With these credentials, I have to say that the OPPO Watch X2 Mini seems like a great recommendation to me. I explain step by step why.

OPPO Watch X2 Mini, our experience

Design: classic and with exaggerated frames. The watch is quite small for a large wrist like mine. Even so, it does not give a reduced experience, quite the contrary: OPPO has made an effort to maximize the X2 Mini in all aspects. From its excellent stainless steel case to the hardware that beats under the 1.32-inch round screen.

The watch is mini, the front shows it. Even so, the frames are thick: around 5 mm. It includes two control buttons that are enough to control anything that is beyond touch. And the back side maintains the heart sensors and a POGO connector for charging. The alignment with the charger is magnetic and said charger has a USB-C port. This way the cable, which also comes in the box, is not damaged.

The OPPO Watch X2 Mini seems like the perfect watch for those looking for a complete smartwatch without feeling like they are lifting weights every time they raise their arm. He’s small, but he’s tough. And with a detail: the strap pin is the standard 18 mm. Finding compatible straps is as simple as it is cheap.

The screen shines with its own light. OPPO mounts an OLED panel that is perfectly visible outdoors, even training in sunlight. The brightness is automatic and adapts without problems to the light conditions. It is compatible with Always On, with what that entails: battery life is reduced in that mode.

The screen has smoothed edges so that the edges do not interfere with gestures. It is tactile and is protected with hardened glass: I did not scratch it during the weeks of testing (miracle). The watch includes a good number of watch faces, supports video watchfaces, and is compatible with the thousands of Wear OS on Google Play. It’s impossible to get bored.

Two is much more than double. When I tested the OnePlus Watch 2 I marveled at the idea of ​​including a dual processor and dual operating system. After the evolution, the OPPO Watch For me it is the way to go in Wear OS.

Smartwatch and activity bracelet chip; with software that maintains this duality: Wear OS when the watch uses apps and RTOS for the rest of the tasks. The result is an experience out of ten: the X2 Watch Mini 2 switches between the SoC and soft tandem without the user noticing anything.

I have not seen it slow, the jump between sports activities is fast, the registrations are accurate, it has access to Google Play and there are no problems with NFC payments. OPPO has the recipe for the best smartwatch and knows how to cook it perfectly in the Watch X2 Mini.

A good watch for amateur athletes. Although I play sports every day (or try to), I do not consider myself an athlete. Yes, I like to keep track of all the training sessions to see the evolution. I use a Garmin Epix 2 and it’s fantastic for me. Well: the OPPO Watch X2 Mini is not far behind.

I have tested the watch running, walking, high intensity routines, strength training and mountain bike rides. The results have been good for a general purpose smartwatch:

• It supports more than 100 sports training modes. Too bad the mountain bike is not available (neither is the padel, sorry).
• Heart rate tracking is sufficiently accurate at low and medium heart rate. Above 150-160 I have seen a margin of error of up to 40 keystrokes. Everything compared to a chest strap connected to the Garmin.

• Related to the previous point, the Watch X2 Mini follows pulse variations as long as they are not triggered by high-intensity interval exercise.
• In outdoor distance measurements, the positioning system remains at a very good level: the margin of error of the routes is around 50 meters per kilometer.
• Very quick positioning before the start of practice: less than ten seconds is usually enough.
• The track record has some saw teeth and may not follow the paths on the map 100% accurately. In terms of total distances, the overall result is decent.

• The personal trainer is suitable for practice, the watch looks great outdoors and withstands harsh weather conditions. Also sweat.
• Recording height is also suitable: use the barometer and GPS for this.
• The bottom button is the direct launcher for the sports modes. In a couple of clicks the watch is ready to measure practice.

I was expecting a generic smartwatch and the truth is that it is not bad at all for following sports practices. It seems perfect to me for those who fall short of the simplicity of an activity bracelet and are looking for measurements with some precision.

The best of all worlds in software. It is a complete smartwatch, it can work in economizer mode without being noticed, it accesses all the advantages of Google Play for Wear OS and it does everything without spending extra mAh. Efficiency is a success. Not missing anything, not even Gemini, maximizes the value of the included software.

OPPO personalizes the experience to your liking by making the system somewhat more minimalist. Both Wear OS and RTOS coexist without fighting: they work transparently for the user and through convenient gestures (apart from physical buttons). With an advantage: it is possible to activate the battery saving mode without losing too much user experience along the way.

With smart mode (smartwatch), the OPPO Watch X2 Mini is a full-fledged Wear OS. Of course, I see one drawback: the watch remains on Wear OS 5 (Android 14), it has not updated to the latest available version, Wear OS 6. And with the November 2025 security update.

Small, but with superior battery. I already mentioned it: having double the main thing makes autonomy grow. From my tests, I have managed to extend the use between charges by up to five days. With daily sports logs, including outdoor GPS runs. And with all the sensors active.

With training sessions lasting several hours, use can last up to four days, perhaps a little less if the exercise is long. Three days of intense use are almost guaranteed, even with an Always On screen. It seems like quite an achievement for a smartwatch that is not exactly huge.

Doesn’t the battery stand out enough? Well, it’s time to load: it’s super fast. A few minutes is enough to last you a couple of days: I have registered about 6 W maximum power. The times were as follows:

• 5 minutes of charging: 22% battery.
• 10 minutes of charging: 44% battery.
• 15 minutes of charging: 64% battery.
• 20 minutes of charging: 78% battery.
• 25 minutes of charging: 88% battery.
• 30 minutes of charging: 94% battery.
• Total: 41 minutes

Battery consumption for eight hours a night, with accurate sleep tracking, is approximately 5%. In sports recording with GPS and screen always on, it consumed 7% every hour.

OPPO Watch X2 Mini, Xataka’s opinion and note

I can’t fault this smartwatch too much: I think it behaves as a watch in this category should. It is true that its battery is not atomic, but five days for a Wear OS is not bad at all. Without diluting the autonomy, without heating up and with all the capabilities one expects in a great watch. Including the assistant, the installation of apps and compatibility with almost any bank card.

It may seem small, but it is very complete. He does not distance himself from his brother, the excellent OPPO Watch. The “they gave me two” in duplicate is the ideal recipe to obtain an experience of ten. It’s not 100% accurate in sports training, but it remains at a good level for someone who doesn’t need to beat their Marathon records. Even so.

For just over 200 euros, the OPPO Watch X2 Mini is a great recommendation for anyone who needs a quality, complete and compact smartwatch. Doesn’t disappoint.
