Appearance&Size&Wear
The Redmi Watch 4 is still a minimalist package, and the black version is also equipped with a pure white magnetic charging wire.
The watchband uses the common watchband clasp pin on the bracelet, rather than the watchband clasp scheme on the watch.
The Redmi Watch 4 is aluminum alloy frame+stainless steel crown+TPU strap, with a circle of bright chamfer on the front, and no screen plastic bracket.
There is no radian on the edge of the screen, and it is directly flush with the border. Apple Watch Ultra calls you "good brother".
The standard quick release wristband of Redmi Watch 4 and Xiaomi bracelet 8 Pro are common. If you happen to have strong financial resources, you can also buy the quick release leather wristband of Xiaomi bracelet 8 Pro (99 yuan) or Milanese wristband (199 yuan) ↑

The 1.97-inch screen of the Redmi Watch 4 is unexpectedly large, which makes it even more huge when you put the Xiaomi bracelet 8 Pro beside it (the Apple Watch Ultra is 1.92-inch, and the Apple Watch Series 7/8/9 is 1.9-inch) (the body of the Redmi Watch 4 is 47.58x41.12x10.5mm, excluding the bulge of the heart rate sensor).
The body of the Redmi Watch 4 weighs 31.5g and the strap weighs 17g. The translation is similar to that of all metal watches such as Apple watches. The watch is still relatively large, and will get stuck on the sleeve like Apple Watch Ultra, or get stuck on the sleeve
The 1.97 inch 60Hz, 390x450302ppi AMOLED screen of the Redmi Watch 4 accounts for 74.8% of the screen, with the highest brightness of 600 nits and a depth of 8bi. It supports the AOD of the lowest 5Hz (claimed that the power consumption is 18% lower than that of the previous generation) (the Apple Watch with a 45mm dial is 7/8/9, with a resolution of 396x484).
The arrangement of screen sub pixels is the same as that of Samsung panel/notebook ↑. It is a low-frequency PWM dimming with black stripe width not changing with brightness, and has automatic brightness.
The brightness of 600 nits is average, but because the dial has a huge number, you can still see the time in the sun.
The brightness of AOD is just fine indoors and in the middle of the night, but you have to raise your hand to light the screen in the sun.

The Redmi Watch 4 is equipped with Xiaomi Bangpai OS. Its functions and layout are very similar to that of Xiaomi 8 Pro (but it has a physical crown). The system response speed and smoothness are OK, and it can basically eat 60Hz.
The most important thing of the meter series smart watch is the customization function. The contents of the home card can be highly customized. The response is extremely fast, and the AOD style can also be customized and edited. With Xiaomi/Redmi mobile phone, you can control the alarm clock of the mobile phone at the watch end.
There is no special funny or big brand co branded dial, but there are more than 200 free dials ↑.
Sports, sleep, heart rate, blood oxygen saturation, pressure, women's health and other detection functions are very mature. It's hard to lose the chain these days. The motion positioning accuracy of the Redmi Watch 4 has not encountered any problems, so we won't say more.
The Redmi Watch 4 has NFC and GPS, speakers, and supports Bluetooth phones.
In fact, compared with the retro vibration motor, Xiaomi/Redmi's RTOS watches now have no fully automatic motion recording function, which is the real reason why I can't touch my hair.
The most outstanding experience of Redmi Watch 4 is its endurance.
The endurance of 470mAh battery is far from the bottom. This is the smartwatch closest to "AOD freedom" that we have experienced in recent years: all detection functions such as AOD+sleep breathing+heart rate+blood oxygen+pressure are fully turned on, and 5% of the power is lost after 9 hours of sleep (if only basic sleep detection function and AOD are turned on, the power is lost by 2%). A few days later, the day that consumed the most electricity only lost 19%.
All the functions of the Redmi Watch 4 can be fully turned on for five days, and some of the excessive health monitoring functions can be turned off. It is not a dream to hit the "AOD that charges once every half month". The official announcement that turning on the AOD off screen display can also have 10 days of endurance (turning off AOD is 20 days, and the long endurance mode is 30 days) is really no joke.
Summary
Now the RTOS watch is really too mature. In addition to the automatic motion monitoring and vibration motor, the basic functions of the Redmi Watch 4 are perfect. The rest is about the appearance and price.
The Redmi Watch 4 can be understood as the Ultra in the Xiaomi/Redmi bracelet series, which is different from the Xiaomi 8 Pro, which is a "male female all-in-one" bracelet. The Redmi Watch 4 focuses on large screen and ultra long endurance.
Now the Xiaomi official store has a Redmi Watch 4 worth 499 yuan, a Xiaomi bracelet 8 Pro worth 399 yuan, a Redmi Watch 3 worth 349 yuan, a youth version of the Redmi Watch 3 worth 299 yuan, and a Xiaomi bracelet 8 worth 218 yuan. Their functions are almost the same. You can choose them according to the screen size and budget (although we recommend the cheapest by default).
