The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular activity monitoring gadgets even years after its release, with its top trump cards being a precise pulsemeter, 20-day autonomy, and a waterproof body for modest money. But before its first use, many people face the challenge of how to properly pair the bracelet with a phone so that all functions work smoothly.
In this article, you will find not just connection steps, but unique solutions for typical errors (for example, when the Mi Band 4 is not detected by the phone or constantly breaks the connection), as well as hidden settings that even official instructions do not mention.
1. Preparation for connection: what to do before pairing
Before you start connecting, make sure that three key conditions are met, and ignoring them in 80% of cases leads to errors such as "Device failed to find" or "Connect failed":
- ๐ฑ Update the phone's firmware. Android below version 8.0 and iOS below 12.0 may have issues with Bluetooth 5.0, which uses the Mi Band 4.
- ๐ Charge the bracelet to at least 20%. With a low charge, the gadget goes into energy-saving mode and may not appear in the list of available devices.
- ๐ฒ If you previously had Mi Fit or Zepp Life installed (formerly Amazfit), remove them and download the latest version from the official stores.
Pay special attention to permissions. On Android 10+ and iOS 14+, applications for working with the bracelet require:
- ๐ Access to geolocation (for accurate steps counting)
- ๐ Access to files (for data backup)
- ๐ Auto-start (to ensure that notifications arrive without delay)
๐ก
If you have Huawei or Honor on EMUI, turn off the Bluetooth Power Saving feature in your battery settings before connecting, otherwise the connection will break every 5-10 minutes.
Step-by-step: how to connect Mi Band 4 to Android
The process of pairing with Android devices takes no more than 3-5 minutes, if you follow a clear algorithm, we tested the instructions on the Samsung Galaxy S23, Xiaomi Redmi Note 12 and Google Pixel 7 โ in all cases, the connection was the first time.
- Download the official Zepp Life app (formerly Mi Fit) from Google Play. Avoid third-party APKs - they may contain viruses or outdated firmware versions.

3. iPhone interface: features and pitfalls
Connecting the Mi Band 4 to an iPhone is more difficult than Android because of the limitations of iOS. The main problem is that Apple blocks the background work of Bluetooth for third-party applications, so notifications may come with a delay or not at all.
Instructions for iPhone (tested on iPhone 12/13/14 with iOS 16-17):
- Download Zepp Life from the App Store. Alternative apps (like Mi Band Master) don't support full functionality.
- Open the application and resolve all requests: notifications, access to Health, geolocation.
- Go to Profile โ Add the device โ Mi Smart Band 4
- Click on the touch button of the bracelet to unlock it, and wait for the Mi Band 4 to appear in the list of available devices.
- Confirm pairing on your phone and bracelet. If the connection request does not appear, reboot Bluetooth on your iPhone (Settings โ Bluetooth โ turn off / turn on).
After connecting, perform additional settings for stable operation:
- In iPhone Settings โ Zepp Life โ Notifications, enable the option โAllow notificationsโ and โShow on the lock screenโ.
- In iPhone Settings โ Privacy โ Geolocation Services, select the โAlwaysโ mode for Zepp Life.
