Connecting Xiaomi Watches to iPhone 8: A Complete Guide to Error Solutions

Xiaomi smartwatches are among the most popular wearables on the market due to their combination of functionality and affordable price. However, iPhone 8 owners often face difficulties in trying to synchronize devices from two different ecosystems. In this article, we will examine not only the standard connection procedure, but also the nuances that arise when working with iOS 15-17 on older iPhone models.

The main problem is that Xiaomi initially optimizes its Android devices, and Apple limits the capabilities of third-party gadgets in its ecosystem. For example, notifications on the clock may come with a delay, and some features (like quick response to messages) will not be available.

We tested compatibility with the Mi Band 7/8, Amazfit GTR 4 and Xiaomi Watch S3 on the iPhone 8 with the latest iOS. All of the steps below are relevant for 2026 and take into account the latest firmware updates. If you have already tried to connect the watch and got an error, at the end of the article there is a section with solutions to 10 common problems.

1.What Xiaomi watch is compatible with the iPhone 8?

Not all Xiaomi smartwatches work equally well with the iPhone 8. The main compatibility criterion is support for Bluetooth 4.2 or later. Here is a proven list of devices that are guaranteed to sync with the iPhone:

  • πŸ“± Mi Band 6/7/8 β€” Budget fitness bracelets with a basic set of functions (stepmeter, pulse, notifications).
  • ⌚ Xiaomi Watch S1/S2/S3 β€” Fully-fledged smart watches with AMOLED-screen-and-support GPS.
  • πŸƒ Amazfit GTR 4/GTS 4 β€” Models with advanced sports functions (measurement) SpOβ‚‚, stress-test).
  • πŸ’Ž Xiaomi Watch 2 Pro – flagship model with support for eSIM (but on the iPhone works without it) SIM-map).

Important! Watches based on Wear OS (such as the Xiaomi Watch S3 in some regions) may require additional settings, and note that the iPhone 8 will not work directly with Apple Health features – the data will have to be exported manually through third-party apps.

If your model is not included in the list, check it on the official Xiaomi website in the section "Compatibility". For example, the old Mi Band 1-5 can connect, but with limited functionality (no call notifications).

2.Preparing iPhone 8 for connection

Before you start syncing, you need to configure the iPhone 8 itself. Here are the key points that are often missed:

  1. Update iOS to the latest version. iOS 17.4 is current at the time of writing. You can check for updates in Settings β†’ Main β†’ Software Update.
  2. Turn on Bluetooth and make sure your iPhone sees other devices. Go to Settings β†’ Bluetooth and activate the function.
  3. Allow notifications for the Mi Fitness or Zepp app (depending on the watch model). This is done in Settings β†’ Notifications β†’ [App name].
  4. Turn off Do Not Disturb mode as it can block notification synchronization.

We also recommend rebooting your iPhone before connecting, which will reset the Bluetooth cache and increase the chances of successful synchronization. If you have previously tried to connect the watch and you have an error, manually remove it from the Bluetooth device list.

If you have iOS 16 or older, turn on Local Network to use the watch in Settings β†’ Privacy β†’ Local Network to improve connection stability.

3. Installation and configuration of the application

To connect the Xiaomi watch to the iPhone 8, you will need an official app.

  • πŸ”Ή For the Mi Band and most Xiaomi Watch, Mi Fitness (formerly Mi Fit).
  • πŸ”Ή For Amazfit - Zepp (formerly Amazfit).
  • πŸ”Ή Xiaomi Watch 2 Pro – Xiaomi Wear (Wear only) OS).

  2. Click "Add device" (the button is usually on the home screen).
  3. Choose your watch model from the list. If you don't have one, try the "Other device" option.
  4. Follow the on-screen prompts. At the connection stage, an iPhone can request permission to access Bluetooth, Notifications, and Health β€” allow everything.

Once successfully connected, the app will prompt you to update the firmware of the watch. Make sure that new versions of the software often fix compatibility errors with iOS. The update will take 5-15 minutes, do not interrupt the process!

  1. Open the Mi Fitness/Zepp app and go to Profile β†’ My Device β†’ Notifications.
  2. Activate the "Call Notifications" and "Application Notifications" switch.
  3. In the "Apps" section, select which programs you want to receive alerts from (for example, WhatsApp, Telegram, Gmail).
