How to connect Xiaomi Mi Band 4 to iPhone: full instructions with error solutions

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular activity-tracking gadgets, despite the release of new models, with its main advantages being affordable price, long battery life and a wide range of functionality from sleep monitoring to smartphone notifications. However, iPhone owners often have questions about how to connect the bracelet to the iPhone, what applications to use and why the device may not sync.

In this article, we will take a step-by-step guide to pairing the Mi Band 4 with an iPhone (including iPhone 6s to iPhone 15), look at alternative apps besides the official Mi Fit, and solve typical problems from the “failed to connect” error to the lack of notifications. If you just bought a bracelet or faced difficulties after updating iOS, this guide will help you set up everything in 10 minutes.

1.What apps are needed to connect Mi Band 4 to iPhone

Xiaomi officially recommends using the Mi Fit app (formerly Xiaomi Wear), but since 2023, the company has been actively moving users to Zepp Life, an updated version with advanced features.

• 📱 Mi Fit is a classic application with basic functions: pedometer, sleep monitoring, notifications.
• ⚡ Zepp Life – modern interface, detailed sleep analytics (including phases) REM), Voice-enabled training, integration with Apple Health.
• 🔄 Notify & Fitness is a third-party solution for those who want to flexibly configure notifications (e.g. filtering messages by app).

Important: Mi Fit is no longer updated for new iOS versions from 2026, so we recommend installing Zepp Life – it supports the latest versions of the bracelet firmware and iOS. However, if you have an older version of Mi Band 4 (for example, with firmware up to 1.0.9.54), you may need to temporarily use Mi Fit for initial setup.

Zepp Life has one key advantage: it automatically syncs data with Apple Health, allowing you to see steps, calories and sleep data in the standard iPhone Health app.This is handy if you use other fitness gadgets (like the Apple Watch) and want to bring all the metrics together in one place.

Step-by-step: how to connect Mi Band 4 to iPhone

Before starting, make sure that:

• 🔋 The bracelet is charged at least 50% (at low charge, Bluetooth may not be turned on).
• 📲 Bluetooth is enabled on the iPhone (Settings) → Bluetooth).
• 📱 One of the apps is installed: Mi Fit or Zepp Life (not both at the same time!).

Follow the instructions:

1. Turn on the bracelet: press the touch button below the Mi Band 4 screen before the logo appears. If the screen does not respond, plug the bracelet into charging for 10-15 seconds.
2. Launch the app: Open Zepp Life (or Mi Fit) and click Profile → Add Device.
3. Select a model: in the list, find the Mi Smart Band 4 and confirm the choice.
4. Allow access: the application will request permissions to: 📍 Geolocation (needed for accurate jogging tracking). 📞 Notifications (to have the bracelet show incoming calls and messages). 🏃 Apple Health (optional for data synchronization).

To reset the pairing on Mi Band 4, press and hold the touch button for 10 seconds until vibration.

3. Set up notifications and calls on Mi Band 4 with iPhone

By default, the bracelet only shows incoming calls, not messages from messengers.

2. Activate the “Call Notifications” and “Notifications from Applications” switches.
3. In iPhone Settings, go to Notifications → Zepp Life (or Mi Fit) and turn on the Allow Notifications option.
4. To filter messages (for example, to make the bracelet vibrate only at important notifications), use the third-party Notify & Fitness app.

The Mi Band 4 only displays text notifications, no emojis or pictures, and it doesn't support responses to messages (unlike the Apple Watch).

• 🔄 Reboot your iPhone and bracelet.
• 📵 Make sure that in the iPhone settings → Mainstream → Data transfer is enabled by Bluetooth (sometimes it is turned off in power saving mode).

One of the main benefits of using Zepp Life is the integration with Apple Health.

1. Open Zepp Life and go to Profile → Settings → Apple Health.
2. Turn on the switches for the parameters you want to sync: steps, distance, calories, sleep data.
3. Confirm access in the Apple Health pop-up window.

The data from the wristband will then be automatically transmitted to Apple Health every 30-60 minutes.

If you use other fitness services (such as Google Fit or Strava), sync can be set up via Apple Health as an intermediary.

1. In Apple Health, allow data to be read for the desired app.
2. In the settings of this app (e.g. Strava), enable data import from Apple Health.
