The situation when the smart watch Xiaomi Mi Watch stops finding a smartphone or break the connection at the most inopportune moment, can anger even the most calm user. It would seem that everything is done according to the instructions, Bluetooth is on, but the gadget stubbornly ignores attempts to pair. Most often the problem lies not in hardware failure, but in software conflicts or outdated communication protocols that are easy to eliminate yourself.
Modern wearables require stable interaction with the operating system, whether it is Android or iOS. Failures can occur at different stages, from initial search to deep synchronization of health data. Understanding the nature of the bug is already half the success in eliminating it, so take your device to the service center.
In this article, we will discuss the main scenarios in which the Mi Watch refuses to work in tandem with the phone, and offer step-by-step algorithms for solving it: you will learn how to clear the cache of Bluetooth services, what resolutions are critical for the Mi Wear application, and why a banal router reboot sometimes helps.
Verification of compatibility and system requirements
The first thing to do is make sure your smartphone model is technically capable of maintaining a stable connection to the watch. Despite the versatility of the Bluetooth Low Energy protocol, some older versions of Android (below 6.0) or iOS may not properly handle data packets from new Xiaomi gadgets.
It’s also worth checking if your phone’s manufacturer has blocked the background work of the services it needs. MIUI, EMUI, or ColorOS shells often have an aggressive power-saving system that kills the synchronization process immediately after the smartphone screen is turned off. The Mi Watch requires constant geolocation access to work properly, even if you’re not using navigation.
⚠️ Note: The iPhone requires iOS version 12.0 or higher to run the watch, and Bluetooth 4.0 enabled. If you have an older iPhone model, pairing may be unstable or impossible.
Make sure that the smartphone has the official Mi Wear app (or Mi Fitness for new models), and not third-party counterparts, which often do not have access to the full functionality of the device.
Problems with Bluetooth and network settings
The most common reason why Xiaomi Mi Watch is not connected is “junk” in the list of paired devices or the failure of the Bluetooth module.The phone may try to connect using an old, already irrelevant protocol stored in memory, in which case a complete cleaning of the list of paired devices helps.
Sometimes the Bluetooth module in a smartphone just freezes and stops seeing new devices, even though the old ones keep working, helps reset network settings, which returns all communication parameters to factory values, it is a safe procedure, but it will remove saved passwords from Wi-Fi networks.
- 🔹 Go to Settings. → Bluetooth and remove all devices associated with the watch (Mi Watch, Mi Band, etc.).
- 🔹 Go to Settings. → System system → Resetting settings → Resetting Wi-Fi, Mobile Internet and Bluetooth.
- 🔹 Reboot your smartphone and try to start the search again through the application.
If they were previously connected to another phone, they must first untie there or perform a reset.Dual connection to different smartphones at the same time is impossible for most Mi Watch models.

Mi Wear app errors and permissions
The companion app acts as a bridge between the watch hardware and the phone's operating system, and if the Mi Wear doesn't have the necessary access rights, the connection will break immediately after the handshake is established, especially when location permissions and background work are critical.
Android owners need to manually check the battery settings for the application, the system can limit its activity to a counting (energy-intensive) process, set the battery mode to "No Limits" for guaranteed stability.
| Permission required | Why? | Default status |
|---|---|---|
| Geolocation (GPS) | Search BLE-device | Requested. |
| Background work | Receipt of notifications | Limited. |
| Memory. | Conservation of dials | Requested. |
| Phone. | Synchronization of contacts | Requested. |
If Mi Wear is not working properly, try clearing its cache and data, which won't delete your accounts, but will reset the settings of the app itself, and then you'll need to re-sign in through your Mi Account.

Charge state and energy saving mode of the clock
Paradoxically, a dilapidated watch battery can block the connection process. If the Mi Watch's charge drops below 10-15%, the device can go into deep sleep mode, turning off the Bluetooth module to save energy, in which state the watch is not visible on the scan.
Put your watch on charge and wait at least 20-30% of the charge before trying to pair. Also check the contacts on the back panel: oxidation or dirt can interfere with normal current, which will make the watch “think” that the battery is empty, even if it is charged.
Sometimes it helps to activate the developer mode on the watch itself, if this option is available in your version of the firmware, but for most users, it is enough to simply restart the gadget by holding the side button for 10-15 seconds.
⚠️ Warning: Do not try to connect the watch to your phone while updating the firmware. This is guaranteed to lead to error and possible "bricking" of the device.
Conflicts of firmware and software versions
Software mismatches are the hidden enemy of stability. If the watch has a very old firmware on it and the Mi Wear app is updated to the latest version, the handshake protocols may not match. And vice versa: the new watch model requires a fresh version of the app.
Check for updates in the app store (Google Play or App Store). Often, automatic updates are delayed and you use a version with known bugs. APK-file.
- 🔹 Remove the current Mi Wear app from your phone.
- 🔹 Download the latest version from the official website or a trusted store.
- 🔹 At the first attempt to connect the watch itself will offer to update its firmware - agree and wait for the end.
💡
If the update of the firmware clock hangs on 50% or 99%, Put your phone and your watch next to you, turn on your phone's Flight Mode (leaving Bluetooth), and wait. 10-15 The process is often completed successfully.
Radical methods: complete reset (Hard Reset)
When soft practices don’t work, the final argument is a complete factory reset, which will remove all data about workouts, dial settings, and tied accounts, but often brings a dead-end Bluetooth module to life.
Resets can be done through the menu of the watch itself: find Settings → System → Reset (or Unbind). If the menu is not available, use a combination of buttons: press the on button and, if available, the second functional button (depending on the model Mi Watch Lite, Color or Pro) for 20 seconds.
After reset, the clock will go into the primary setting mode, displaying QR-It's important not to try to connect them through the Bluetooth system menu of the phone.
💡
Hard Reset solves 90% of software connection problems, but requires reconfiguration of the device from scratch.
