Why Mi Band 4 doesn’t turn on after reset and what to do about it
You reset your Xiaomi Mi Band 4, but now your fitness bracelet is refusing to turn on? This is a situation that many device owners know about. The reasons can be both banal battery discharge and software failures after a wrong reset. It's important to understand that the hard reset on the Mi Band 4 erases all data, including paired connections to the phone, but does not damage the hardware.
The first thing you need to check is the level of charge, even if the bracelet was showing you before it was dropped. 30-40% When you charge it, the zero settings process can discharge it to zero. 10-15 If the charging indicator doesn't light up, the problem could be in the cable or the port - try another one. USB-power-couple.
Another common mistake is to try to turn on the bracelet immediately after reset without waiting for the process to be completed. The Mi Band 4 screen displays reset animation (rotating indicator) during the hard reset, and you can not interrupt it. If you pull the device from charging or press a button at this point, the probability of software freezing is high, in which case only resetting will help, in all conditions.
Preparation for Including: What to Do Before Activation
Before you turn on the Mi Band 4 after reset, follow a few mandatory steps, which will save you from the typical problems like the inability to connect to the phone or sync failures.
- 🔋 Charge the bracelet to at least 50%. Once reset, the device spends a lot of energy on the initial setup. Low charge can cause the device to shut down again in the process.

- 🔄 Reboot your smartphone. This clears the Bluetooth cache and eliminates possible conflicts with other connected devices.
Pay special attention to the firmware version of the bracelet. If you used custom firmware before reset (for example, Amazfit or a modified Mi Band 4 Firmware), after the hard reset, the device may return to the stock version. This will lead to incompatibility with certain functions in the Mi Fit. Check the firmware version in the bracelet settings after turning on - if it differs from the expected, you will need to re-firm.

- 🔌 Short circuit when charging (for example, if the bracelet fell into water).
- 📉 Critical battery discharge (below 2.8V) after which the power controller blocks the charge.
- 🛠️ Unsuccessful firmware through third-party utilities.
