How to sync Mi Band 3 with Xiaomi phone: a complete guide to error solutions

The Xiaomi Mi Band 3 fitness bracelet remains a popular gadget even years after its release, thanks to its reliability, long battery life and wide functionality. However, many users face difficulties when first syncing a device with a Xiaomi smartphone, especially if it comes to new phones or updated versions of firmware. In this article, we will analyze not only the standard connection procedure, but also the nuances that the manufacturer does not say: from choosing the right application to avoiding typical errors like “failure to find the device” or “synchronization failure”.

It’s important to understand that the Mi Band 3 is officially supported through two apps — Mi Fit (obsolete) and Zepp Life (recommended by Xiaomi since 2022), while the connection algorithm to Xiaomi phones has its own peculiarities due to integrated MIUI services that can block the background activity of applications. If you have already tried to sync the bracelet and got an error, do not rush to reset: 90% of the time the problem is solved by adjusting permissions or reinstalling the software.

We tested the process on Xiaomi 13 Pro, Redmi Note 12 and POCO X5 phones with the latest versions of MIUI (14.0.5+), as well as on bracelets with firmware from 1.6.0.44 to 1.9.0.18. All instructions are current for 2026 and take into account the latest changes in Xiaomi’s policy on working with wearable devices.

1. Which app to choose: Mi Fit or Zepp Life?

Until 2021, the Mi Band 3 was synchronized exclusively through Xiaomi’s official Mi Fit app, but after rebranding the wearables ecosystem, the company moved support to the Zepp Life platform (formerly known as Amazfit), both of which theoretically work with a wristband, but there are critical differences:

• 🔹 Mi Fit: outdated interface, limited customization options, but stable with notifications on older versions of Android (up to 11).
• 🔹 Zepp Life: Modern design, advanced sleep and workout analytics, but background synchronization bugs on Xiaomi due to aggressive optimization MIUI.

Our recommendations:

• 📱 If you have Xiaomi on Android 12+ (MIUI 13/14) — Use Zepp Life, but pre-disable battery optimization for the app.
• 🔄 For Android phones 9-11 (MIUI 12 Mi Fit is better – less problems with notifications.
• ⚠️ Don’t install both apps at the same time, and this will lead to synchronization conflicts and duplication of notifications.

⚠️ Note: When you first start Zepp Life on Xiaomi phones, the app may request access to Google Play Services for geolocation. This requirement is due to Google’s new rules for wearables – waiving permission won’t affect the core functionality of the wristband, but will disable route tracking while jogging.

7.Mi Band 3 battery optimization when synchronized with Xiaomi

One of the frequent complaints users have is the rapid discharge of the bracelet after connecting to Xiaomi, which is due to the fact that MIUI aggressively scans Bluetooth devices in the background, even when the bracelet is not in use.

• 🔋 In Zepp Life, turn off Permanent Connection (located in Device Settings) → Advanced settings. This will reduce background Bluetooth activity.
• 📴 Reduce the frequency of data synchronization: set the interval to 30-60 minutes instead of automatic mode.
• 🚫 Turn off unnecessary notifications (such as social media) that often wake up the bracelet.
• 🌙 Activate Don’t Disturb at Night if you don’t need sleep monitoring.

Comparison of working time under different settings:

If the bracelet discharges in 1-2 days for no apparent reason, check:

• 🔍 Are there any background processes running in Zepp Life (go to Settings) → Annexes → Zepp Life → Battery utilization).
• 📲 Are there conflicts with other Bluetooth devices (headphones, smart watches).
• 🔄 Relevance of bracelet firmware (outdated versions may have power consumption bugs).
