Choosing wearable electronics in 2026 has become a daunting task due to the sheer number of models being produced by the Chinese giant's ecosystem: Users are often lost in acronyms and numbers, trying to figure out which good Xiaomi fitness watch will suit their use cases, whether it's professional running or simple step counting.
This year, the company has been betting on hybrid operating systems and advanced biometrics, allowing devices to last up to three weeks without recharging even when using GPS actively.

⚠️ Note: Make sure the chosen model supports NFC in your region, as global versions often lack the contactless payment feature available only in Chinese versions.
Flagship line: Xiaomi Watch S and Pro series
The company’s 2026 engineering pinnacle is the Watch S3 and Watch S4 series, which offer premium materials and advanced functionality, and are equipped with sapphire glass and stainless steel or titanium cases, making them resistant to scratches and impacts.

⚠️ Note: eSIM activation is only possible for operators that support this technology and requires separate charging, which increases the cost of maintaining the device.
Budget champions: Redmi Watch and Mi Band
The most popular category is the affordable trackers like the Mi Band 9 and Redmi Watch 4, which offer 90% of the flagship’s functionality for a third of the price, ideal for beginners who want to start monitoring their health without overpaying for unnecessary options.

Comparison of technical characteristics of models
To make a final decision, a detailed comparison of key parameters of the popular 2026 models is needed, and the table below will help visualize the differences between the device categories.
| Model | Case material | Time to work. | GPS | NFC |
|---|---|---|---|---|
| Mi Band 9 | Aluminum/Plastic | 21 days | Built-in | No (Global) |
| Redmi Watch 4 | Aluminum alloy | 20 days | Built-in | There is. |
| Watch S3 | Nerzh. | 15 days | Two-frequency | There is. |
| Watch 2 Pro | Titan | 5 days | Two-frequency | There is. |
As the data shows, the difference in autonomy between HyperOS-based models and simpler systems can be substantial, depending on whether you prefer the duration of the operation or the advanced smart features.
Why is working time different?
Software and ecosystem
All devices are managed via the Mi Fitness app (formerly Zepp Life), which underwent significant changes in 2026.The interface has become more logical, and data synchronization occurs almost instantly after the application is opened.
Users can customize their dials, update their firmware, and analyze sleep phases and stress levels in detail. Health analytics now includes a fitness assessment (PAI) and recommendations for recovery.

Device care and extension of service life
For the gadget to last, it is necessary to regularly clean the sensors of sweat and dirt, using soft fabric and a small amount of water. Aggressive chemistry, such as alcohol or solvents, can damage the oleophobic screen covering and sensors.
It is recommended to reboot the device at least once a month through the settings menu to clear the cache and fix possible software glitches.It is a simple procedure that often solves problems with breaking the Bluetooth connection.

- 🔋 Do not allow the battery to be below 0%.
- ❄️ Avoid extreme temperatures (sauna, frost below) -10°C).
Compliance with these simple rules will allow you to maintain the presentable appearance and technical serviceability of the device throughout the entire life of the device.
⚠️ Warning: Do not charge the device immediately after applying it from the cold into a warm room - condensation inside can cause a short circuit.
