Introduction and inboxing
This is Xumi’s watch S4 and is now one of the most custom smart watchs you receive. It comes in the same 47 mm version and in three cases – silver, gray and black, but in the case, Bezel can be converted to a fly, which gives you practically non -ending options.
We have a rainbow model, which is more shade than black. It comes with a unique black bezel and a fluorber strap with a unique black bezel and multi -color stitch. The time of this article is € 170.
The clock inside the retail box, its strap, and 2 pin is a magnetic charger. The charger uses the USB -A plug, which is disappointing in 2025. It is also slightly lower to connect the charger properly – rival watches like Samsung’s Galaxy Watch and Huawei Watches also use a proprietary charger, but it is magnetic – just plop the top watch and forget about it.
What is inside the box?
We also have extra dual tone ceramic bezel and a strap kit, which completely eliminates the appearance of the clock. The clock is also smart about changing the bells – now when you remove the bezel, now there is a warning – the clock is permanently vibrated until you keep the bezel back to the clock. A welcome change, considering how easy it was to pop and lose the bezel on Watch S3 accidentally.
There is a serious style of procedure in this case, where Bezel is locked in place.
Extra camera bezel and leather strap
The quality of design and construction
Even better, Xumi moved with the size of a standard 22 mm band, which opened the world of both the third party and the Xumi strap. Who does not love different types?
Hundreds of Amazon, Alexpress, and so on, real leather, fake leather, rubber, ballistic nylon and more, if not, thousands, 22 mm watches. But there are already third party bees for Watch S4, so you can customize your heart content!
The Classic form of the Xumi Watch S4. Bezel is significantly sitting on the round case and the screen is spread a few millimeters above the glass cover, and protects it from scratches.
The matter is made of aluminum alloy, while Xumi does not tell anything about glasses, but we will know that it has some level of scratch resistance.
Although some watches use more rigorous and premium stainless steel for the outer, aluminum used in Xiaomi Watch S4 allows only 44.5 grams of lightweight package. In comparison, the OnePlus Watch is 3 49.7g, while the Galaxy Watch is 6 classic 59 grams.
The screen is a great improvement than your predecessor. It is a 1.43 -inch 466x466px 60Hz unit which brought the old 600 knots to 2,200 nets. This is a remarkable clash – this panel wants you nothing, even in the brightest situation.
There is always an on -screen format that is in line with each individual’s watch face.
There are two controls to the right side of the Xumi Watch S4 – a new rotating crown, which doubles as Pushir, and below it there is another button that sits more flush with this case.
The rotating crown adds a welcome layer of control to the smart watch. This is exactly, and it has a beautiful vibration opinion.
Control
Heart rate and blood oxygen sits at the bottom of the clock clock (it is bright in green and red). This is the place where two pins to sit on the magnetic charger.
1.43 inch 466x466px AMOLED display, once again, excellent – crisp and bright. But it is Xiaomi’s attempt to make the face of a sophisticated watch that makes it even better. Here are nine built -in faces, all high quality, a thousand features of customized widgets for all data. Battery life, steps, weekly days, etc.
Our only slight grip is that all the clock faces are black. In the MI fitness app you can find a lot of extra faces, so it’s all good.
The Xumi Watch S4 is a kind of unique type in which it is a large watch of 47 mm, but also light. This is for the unique user who likes them big but light! The clock S4 lends yourself exactly on fitness or sleep tracker duty.
On the other hand, those who love a little love on their watch will not be the greatest fans.
Xiaomi equipped the clock S4 with its Hyperson 2, which has a smooth device connection with Xumi’s smart center. A push on the crown takes you to the grid of your apps, another back on the main watch screen. A swipe from above brings notifications, bringing a swipe down to the bottom side of your sets.
Notifications are fundamental. You get a series of swimming messages that you can tap to fully view and then delete. You can’t answer the clock, and the messenger emojis is not supported, so you find a strange sign.
What is unique about Xiaomi Watch S4 is that when you do left and right swipe on the main screen, nothing happens (Well, a swipe left gives you a way to change the clock face) – most other smart watches have a horizontally scarbal interface.
A push on another button opens the quick toggle.
There are also indications. You can rotate or shake your wrist, or snatch your fingers to get numerous customized steps – reject the call, pull photos (though you need to open the camera app on your phone, and a watch camera app is open on the watch), or opening the weather app. We tried them, but we cannot say that they work permanently.
Sadly, physical control is not customized.
Fitness and sleep tracking, battery life
The Xumi Watch S4 has excellent sports and health tracking certificates, as you will expect. Referring to the One Perger, you find more than 150 sports ways. Which includes a personal running coach, and even a professional skiing mode (rare on many watches).
The Watch S4 supports double band GPS, which uses both wider L1 and faster and more accurate L5 bands to provide tracking accuracy within the meter. We got GPS lock in about 40 40 seconds, and the map data was very accurate.
Fitness tracking
We are happy with fitness tracking on the Xumi Watch S4. The exercise screen is well kept in front and center of exercise and intensity. We would also say that the heart rate was in accordance with other brand fitness trackers.
The reviewer has never been a fan of the excessive sleep tracking data from the Xiaomi watches. I don’t get more than 50 minutes of deep sleep per night, as Samsung’s Galaxy watches and Galaxy are established by daily tracking with Galaxy, Huawei’s GT and Fit Series – none of them have given me an hour deep at night. Xumi watches estimates that I get more than 2 hours deep every night.
Yes, it is true that out of lab testing, sleep tracking is mostly estimated, but more than 2 hours deep sleep is bondable for appropriate people.
Placing natpic aside, tracking Xiaomi’s sleep gives interesting matrix to compare your sleep to other consumers, assign you sleep animals, and distribute points related to ways to improve your sleep.
To keep track of detailed sleep
Xumi claims that you can get a battery up to 15 days with “normal use” from 486mah battery on the Watch S4. This editor is a mature believer that the watch, digital or not, needs to be displayed all the time, so I always used the clock S4 with a display and notifications, an hour daily exercise, and nighttime sleep tracking. I got the most three days, but the clock died nearby. Two days were a permanent result. If you turn off the AOD and wake up stike to wake up, you can squeeze more than Xumi Watch S4 if you do not use the use of sleep tracking.
Conclusion
You can get the Xumi Watch S4 below € 200 – a huge price. Usually it is € 170 but often has a discount of 10 % or 20 % – we like a contract. In terms of construction standards and sugars, smart watchs are more expensive around S4.
This makes it easier – Xumi Watch S4 is an excellent time piece with top tear sunglasses at a large price. We have little to complain except the 2 pin magnetic charger.
