Is it more important to have an exquisite and beautiful appearance, comfortable wearing and easy disassembly, or is it more important to have a long battery life and rich functions? Especially now that smart watches are in full bloom. Huawei, OPPO, Xiaomi, Apple and other brands have their own masterpieces, leaving consumers spoiled for choice. Which one is worth buying?
Today we will select the most representative Huawei Watch 3 Pro, OPPO Watch 3 Pro and Xiaomi Watch S1 Pro from the current market, and make a horizontal comparison in 7 major dimensions: appearance, performance, interaction, sports and health, application ecology, charging life, and price to see who performs better and is more worth buying.

Appearance comparison
First of all, in terms of appearance design, both Huawei Watch 3 Pro and Xiaomi Watch S1 Pro adopt a very classic round dial design, and the surface is covered with sapphire glass mirror. The former is also equipped with a titanium body and a microcrystalline ceramic back shell, which is full of texture. Xiaomi has a stainless steel body and a leather strap to achieve good performance and full of business atmosphere. In comparison, OPPO Watch 3 Pro looks younger. It has a very unique curved screen. The entire curved design extends from the screen to the strap. The recognition is indeed quite high. The combination of the aluminum alloy body and the leather strap is also good, and the appearance is very online.

As for the display effect, Xiaomi Watch S1 Pro's 1.47-inch narrow-framed screen has a resolution of 480x480, a maximum display brightness of 600nit, and supports AOD screen display. It can display some important information without manually lighting up the screen. Huawei Watch 3 Pro is equipped with a 1.43-inch AMOLED screen, and the parameters are equally good. The LTPO flexible curved screen of OPPO Watch 3 Pro has a larger 1.91-inch display area, 326PPI, and a brightness that can reach 1000nits. The display is clearer in outdoor high-brightness environments. It supports AOD screen display and LTPO functions. The refresh rate can be reduced to a minimum of 1Hz to extend the overall battery life, which is more prominent in comparison.

Performance comparison
As for performance, the three products all use different chip solutions. OPPO Watch 3 Pro and Huawei Watch 3 Pro both use dual-core architecture, driven by a high-performance chip and a low-power chip. This will undoubtedly better ensure the experience of the watch in terms of battery life and smart functions. OPPO Watch 3 Pro uses the latest flagship core Snapdragon W5, which has even better performance. As for Xiaomi Watch S1 Pro, the watch is equipped with a single chip, BES2500BP, and the smoothness is also good, but in comparison it is not as good as the other two.

Sports and health
In terms of sports and health, all three watches support more than 100 sports modes, covering common running, cycling, mountain climbing, surfing , etc., and the sports functions are quite rich. In terms of body index monitoring, OPPO Watch 3 Pro and Huawei Watch 3 Pro can support real-time monitoring of important data such as heart rate, blood oxygen , ECG, blood vessels, etc. to help users further understand their physical condition. Xiaomi Watch S1 Pro supports heart rate and blood oxygen index monitoring, but does not support ECG and vascular health monitoring.
Interactive experience
Regarding the most important interactive experience of smart watches, all three watches can be linked with mobile phones and electronic products of the same brand, among which OPPO Watch 3 Pro and Huawei Watch 3 Pro is even better, supporting eSIM independent communication function and NFC function. It can make and receive calls, send and receive WeChat messages, flash code payment and other operations without the mobile phone. It can also be used as a transportation card, access control card, and you can go out for a night run or walk the dog without a mobile phone. It is more independent and more practical.

The Xiaomi Watch S1 Pro only supports the NFC function. Although it can also perform functions such as door cards, transportation cards, and bank cards, it basically requires a mobile phone to be carried around, and its independence is slightly lacking.
application ecology
application ecology has always been a shortcoming of the Android watch camp, and we can see from the detailed information on their respective product pages that in terms of quantity alone, OPPO Watch 3 Pro and Huawei Watch 3 Pro can support the download of more than 80 App applications, covering all areas of daily life. They have been adapted to common applications such as WeChat, Alipay , maps, news, sleep health, etc., and can meet the needs of most users. There are more than ten models of Xiaomi Watch S1 Pro. If they are adapted for maps, music, calculators and health functions, their practicality is somewhat limited.

Battery life and charging
Battery life has always been a major pain point for smart watches. Even if it is better than Apple Watch, it only needs to be charged once a day. So how do these three products perform? Judging from the official data, Huawei Watch 3 Pro has a battery life of 5 days/21 days under regular/power-saving use respectively; Xiaomi Watch S1 Pro can get 5 days of use when the AOD function is turned on, and the maximum battery life is 14 days; OPPO Watch 3 Pro has 5 days of use in full smart mode, and the light smart mode can be extended to 15 days. It seems that the performance of the two is indeed quite close, and both belong to the level of long battery life.

In terms of charging, all three products support magnetic charging. Huawei supports wireless charging, while OPPO Watch 3 Pro supports fast charging technology. It can be used for one day after charging for 5 minutes, which greatly alleviates battery life anxiety.

price
Finally, there is the price issue that everyone is concerned about. Comparing the prices of the three products, we can see that Huawei Watch 3 Pro is the most expensive, currently priced at 2,599 yuan, and is more suitable for business people with sufficient budgets and seeking to be mature and stable. Xiaomi Watch S1 Pro is currently priced at only 1,599 yuan, making it the cheapest of the three products. It is more suitable for consumers with limited budgets, pursuing cost-effectiveness, and not having high requirements for smart attributes. As for OPPO Watch 3 Pro, currently priced at 1,899 yuan, it is more user-friendly than Huawei, and comes with a high-quality appearance and a comprehensive and balanced experience, making it more cost-effective overall. So, if it were you, what would you choose?
