Connect Xiaomi Mi Band 4 to iPhone 11: full instructions with solutions to problems

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular gadgets for tracking activity, despite the release of new models. Its combination with the iPhone 11 is a common pair, but many users face the nuances of synchronization due to the peculiarities of the Apple ecosystem. Unlike Android devices, where the connection is almost automatic, iPhone owners have to consider the limitations of iOS and the specifics of the Mi Fit application.

In this article, you will find not only step-by-step instructions for connecting, but also a breakdown of typical errors (for example, when the bracelet does not find the phone or constantly breaks the connection), as well as hidden settings that will help optimize the work of the gadget. We tested all the steps on the iPhone 11 with the latest version of iOS, so the instructions are relevant for 2026. If you have already tried to connect the bracelet and encountered problems, pay special attention to the section on troubleshooting.

1.Preparation for connection: what to check before starting

Before you start synchronizing, make sure all the components are ready to go, and failure to do so is the main cause of 80% of connection errors.

• 📱 iOS Version: Your iPhone 11 should have iOS 13.0 or later installed. Check in Settings → Mainstream → Older versions of iOS don't support the latest Mi Fit app updates.
• 🔋 Bracelet charge: Mi Band 4 battery level should be at least 20%. At low charge, the bracelet can be turned off during synchronization.
• 📶 Bluetooth and geolocation: Turn on Bluetooth and allow the Mi Fit app to use Geolocation Services (this is Apple's requirement for devices that work with health sensors).
• 🌐 Internet connection: For the first setup, you will need stable Wi-Fi or mobile Internet (3G/4G/5G). Without it, you can’t load the bracelet firmware.

A critical note for iPhone owners: the Mi Fit app does not support the Find iPhone feature to search for the bracelet. If you lose the Mi Band 4, you won’t find it through the Apple ecosystem, just through the built-in alarm clock on the bracelet itself.

2.Installation and configuration of the Mi Fit app on iPhone 11

The official Mi Fit app is the only way to fully connect the Mi Band 4 to an iPhone. Alternative programs (like Notify & Fitness) offer limited functionality and often run unstable. Download Mi Fit from the App Store directly.

After installation, follow the following steps:

1. Account registration: Open the app and create a Xiaomi account (or sign in through an existing one). Use a valid email and it will receive a confirmation email.
2. Application permissions: When you first start up, Mi Fit will request access to the app: 📍 Geolocation services (mandatory! 📁 Notifications (to display alerts from the phone on the bracelet) 🏃 Apple Health (to synchronize health data)

⚠️ Note: If you refuse access to Apple Health, the data on steps, sleep and heart rate will not sync with the standard app Health on the iPhone.
