How to set up Xiaomi Mi Band 4 after a complete reset: from synchronization to fine-tuning

Resetting the Xiaomi Mi Band 4 to factory settings is a necessary measure when you freeze, sync errors or before selling the device. However, after this procedure, the bracelet becomes a “clean sheet”: tied accounts, activity data, individual screen settings and notifications disappear. Without the right setup, the Mi Band 4 will not be able to track sleep, show incoming calls or even correctly display time.

In this article, you will find step-by-step instructions for restoring the bracelet after resetting – from basic synchronization with the Mi Fit application (or Zepp Life) to fine-tuning notifications, alarm clocks and branded chips like PAI (We'll also look at the common mistakes that occur when you re-bind your device and give you recommendations for optimizing your autonomy, so if you forget all the settings, don't panic, you can bring it back to life in 10-15 minutes.

Preparation for setup: what to do before synchronization

Before you start setting up the Mi Band 4 after reset, make sure you have everything you need. Without preparation, the process can be delayed due to lack of data or incompatibility of software versions.

First, check the firmware version of the bracelet, which can roll back to the factory after it's reset, which will lead to conflicts with the current app, to avoid problems:

• 📱 Install the latest version of Mi Fit (for the first time) Android/iOS) Or Zepp Life (an alternative app from Xiaomi) download only from official sources: Google Play or App Store.
• 🔋 Charge the bracelet to at least 50%.Discharged device can interrupt the synchronization process.
• 📡 Turn on Bluetooth on your smartphone and make sure there are no other devices with an active Mi Band connection nearby (like a second phone or tablet).
• 📝 Prepare the data from your Xiaomi account (login and password) if you used it for synchronization before. Without authorization, you will not be able to restore your activity history.

💡

If you have forgotten the password from your Xiaomi account, restore it PROVIDED through the official website account.xiaomi.com. After resetting the bracelet, the system can request a reauthorization, and without access to mail the process is blocked.

Pay special attention to your account region: If you have previously used the Chinese version of Mi Fit (for example, for firmware with AliExpress), after the reset, you may have problems with linking to a global account.

⚠️ Note: If the bracelet was purchased in China and stitched under the regional version, before resetting, untie it from the Chinese account through the Mi Fit settings. Otherwise, after reset, the device may not be recognized by the global application.
