Owners of Xiaomi Redmi smartphones 9T Often faced with the dilemma of choice of accessories, as this device, having a powerful battery and NFC-It's a module that can unlock the full potential of today's wearable electronics, but the Android ecosystem that the shell is based on. MIUI, It requires a careful approach to pairing devices to avoid problems with synchronization and energy consumption. A properly selected gadget will not only be an addition, but a full extension of the functionality of your phone.
The current market is oversupplied, but not all devices are stable with the Snapdragon 662 processor installed in this smartphone model. Compatibility plays a key role here, as older versions of Bluetooth or specific data protocols can cause notifications to be out of sync. It is important to consider not only the brand, but also the software that manages communication between devices.
In this article we will analyze in detail, Xiaomi Mi Band, Amazfit or third-party brands like Huawei and Samsung best proved themselves in a pair with Redmi 9T. You will learn about the intricacies of setting up the background work of applications that are often “sutumbed” by the energy saving system, and get answers to the most frequent questions of users.
Technical requirements and compatibility of Redmi 9T with wearable electronics
For smart accessories to work smoothly, your smartphone must meet certain technical criteria, which the Redmi 9T happily fully covers.The device supports Bluetooth 5.0, which is a modern standard that provides low power consumption and a stable communication channel up to 10 meters without obstacles, which allows even advanced watch models with a constant flow of data without fear of frequent connection breaks.
However, the operating system version and the availability of the necessary permissions remain an important nuance. MIUI is known for its aggressive energy saving policy, which can force the background processes of companion applications. Synchronizing health data and notifications requires that an intermediary application (such as Mi Fitness or Zepp) has constant access to the network and system.
⚠️ Note: If after connecting the hours, notifications stopped coming through 15-20 The system has closed the background application, so you need to manually prevent the system from "killing" the synchronization process in the battery settings.
RAM is also worth considering, although 4GB or 6GB in the Redmi 9T is enough to run instant messengers and wearable services simultaneously. Problems can only arise with very old watch models released before 2016 that use outdated encryption protocols that are not supported by new Android security patches.
Top Manufacturers: Xiaomi, Amazfit and Third-Party Brands
When choosing an accessory for the Redmi 9T, it is logical to pay attention to the products of the Xiaomi and Amazfit ecosystem. These devices are designed with the specifics of MIUI, which ensures native integration and minimal bugs. Fitness trackers from these manufacturers are usually cheaper than their competitors with the same functionality, since they do not require the installation of heavy third-party launchers.
However, Samsung and Huawei devices also do great. Watches based on Wear OS (Google’s operating system) provide maximum functionality, turning the wrist into a mini smartphone, but this comes at a cost with more frequent recharging. For the Redmi 9T with its huge battery, this will not be a problem, but the user may face the need to charge the watch every day.
- 🏆 Xiaomi Mi Band – the perfect balance of price and quality, the best autonomy (up to 14 days) and deep integration with the system.
- ⌚ Amazfit GTS/GTR — More premium design, built-in GPS Extended sports modes for professionals.
- 📱 Samsung Galaxy Watch – a full-fledged operating system, the ability to install applications and respond to messages directly from the screen.
- 🔋 Huawei Watch Fit is a great screen AMOLED fast charging, but may have difficulties with the installation of proprietary software.
When choosing between brands, you need to prioritize: if you want just steps and notifications, take trackers. If you want full phone management, watch calls, and cards, look for a full-fledged smartwatch with an operating system.
💡
When buying watches from third-party brands (not Xiaomi), be sure to check the availability of charging cable, as the standards of the connectors may differ from the usual magnetic docks Mi Band.
Instructions for primary connection and setting
The process of pairing Redmi 9T with a new device is quite simple, but requires a sequence of actions. First you need to download the corresponding application from the Google Play Market. For Xiaomi and Amazfit devices, this is Mi Fitness (formerly Zepp Life) or Zepp, for Samsung – Galaxy Wearable, for Huawei – Health.
Once you install the app, take your time to turn on Bluetooth in your phone settings. Start the app, create an account or log in to an existing one, and then go to the device search, which will allow the system to correctly register the gadget and assign the necessary access rights to it.
Settings → Bluetooth → Search for new devices → Choosing the name of the watch → Confirmation of the codeThe critical step is to set the permissions. When you first run the app will request access to geolocation, contacts, microphone and background work. All permissions must be given, otherwise the functionality will be cut, especially allowing auto-start and operation in the background so that the watch does not switch off from the phone when the smartphone screen goes out.

Comparison of popular models: characteristics and functions
To make a final decision, let’s compare the key parameters of popular models that are guaranteed to be friends with the Redmi 9T. The table below will help visualize the differences in autonomy, protection and available features.
| Model | Autonomy | Protection (ATM) | Features |
|---|---|---|---|
| Mi Band 8 | 16 days | 5 ATM | Bracelet mode, footwear attachment |
| Amazfit Bip 3 | 14 days | 5 ATM | Built-in GPS, big screen |
| Samsung Watch 4 | 2 days | 5 ATM + MIL-STD | Wear OS, NFC-pay, call |
| Huawei Band 7 | 12 days | 5 ATM | Thin body, AMOLED matrix |
As you can see from the comparison, autonomy is very dependent on the type of device: trackers work for weeks, while full-fledged smartwatches require daily recharging. However, the functional gap between them is gradually narrowing, even simple bracelets can now measure blood oxygen levels and stress.
⚠️ Note: Manufacturer's declared autonomy (e.g, 14 The only time to use it is when the screen is bright and the pulse is continuously monitored off. 30-40%.
The AMOLED arrays used in most modern Xiaomi models provide deep black and high brightness, which is great for reading in the sun. This is especially important for the Redmi 9T, which also has good brightness indicators, and there will be no imbalance in the quality of the picture.

Solution: Notification and synchronization problems
Despite its good compatibility, Redmi 9T users may encounter a situation where the clock is running but notifications from Telegram, WhatsApp or calls are not coming.This is a classic Android problem that is solved through system settings. You need to find the running companion app in the list of recent programs and "lock" it so that the system does not close it.
To do this, click on the square (the menu of running applications), find the app window for the watch and click on the lock or select "Secure". Also in the battery settings (Settings → Battery and Performance), you need to find the application and set the "No Limits" mode.
- 🔒 Fixing the application in RAM prevents its unloading by the system.
- 🔔 Notifications must be allowed in both the companion app itself and in the Android system settings.
- 📶 Bluetooth must be active all the time; do not use energy-saving modes that disable wireless modules.
Another common problem is time desynchronization, and if the clock is not showing the right time, try to find the "Sync Time" option in the companion app or simply reboot both devices, which usually solves the problem, since the Redmi 9T receives the exact time from the operator's network.
💡
The main reason for missing notifications on Redmi 9T is aggressive MIUI optimization, the solution lies in manually removing the limitations of background work for the watch management application.
Expansion of functionality: additional opportunities
Using the Redmi 9T bundle and smartwatches opens up features that are not available when using a smartphone alone. For example, you can use the watch as a remote camera. By setting the appropriate resolution in the app, you can take group photos by simply pressing a button on your wrist while the phone is on a tripod or lying on a table.
Also useful is finding a phone. If you lost the Redmi 9T at home, double-pressing the clock button (or a special command on the menu) will make the phone ring loudly, even if it is in silent mode.
For athletes, the ability to use built-in GPS in the watch (if there is one in the model) is important, which allows you to run or ride a bicycle without a phone, leaving it at home, and then synchronize the route with the Redmi 9T for statistical analysis.
