After resetting the Xiaomi Mi Band 4, many users face a problem: the bracelet does not turn on, does not respond to charging or does not connect to the Mi Fit application. The reasons can vary from a discharged battery to software failures. In this article, we will analyze all possible scenarios and give step-by-step instructions on how to bring the bracelet back to life without contacting the service center.
It's important to understand that resetting the Mi Band 4 erases all the data: steps, pulse, alarm settings and notifications. However, the device itself remains functional - it just needs to be properly restarted and re-synchronized. If you see the Mi logo on the screen, but nothing happens next, or the bracelet vibrates and goes out - do not panic. 90% of the time, the problem is solved in 5-10 minutes.
We tested all the methods on firmware bracelets 1.0.9.54 and 1.0.9.62 (current for 2026) and identified the most reliable methods. If your Mi Band 4 does not show signs of life after reset, start by checking charging - this is the most common cause of "dead" state.
Why Mi Band 4 doesn’t turn on after resetting
Hard reset on Xiaomi Mi Band 4 is done by holding the touch button for 10-15 seconds, and then the bracelet should reset and show the welcome screen, but sometimes it doesn't. Here are the main reasons:
- 🔋 Battery discharge: If the charge is below 5%, the bracelet will not turn on even after resetting.
- 🔌 Charger problems – unoriginal cables or dirt in contacts can block power.
- 📱 Conflict with the Mi Fit app – if the reset is performed during synchronization, the bracelet can “hang” in standby mode.
- 🔄 Incomplete reset – if you hold the button for less than 10 seconds, the device will not reset to factory settings.
- 🛠️ Software failure is rare, but it happens that the firmware gets damaged, and then flashing through Mi Fit will help.
According to service center statistics, 60 percent of the time the problem is a dead battery, another 25 percent is a faulty charger, and only 15 percent is a software bug that requires more manipulation.
Preparation for inclusion: checking charging and contacts
Before you try to turn on the bracelet, make sure it charges correctly. Even if you are sure that the battery was charged, follow these steps:
- Check the contacts - the back of the Mi Band 4 has two metal contacts (gold color) that should be clean, without oxidation or dirt.
- Use the original cable - non-original chargers may not provide the right current. If you lose your native cable, take a certified 5V 0.5A.
- Connect to a power source - it is better to use USB-port of your computer or smartphone charger (not fast charging!). Avoid high voltage ports (e.g. power bank).
- Wait 15-20 minutes — even if nothing is displayed on the screen, give the bracelet time to charge. The charging indicator (red light bulb) should light up in 5-10 minutes.
If the bracelet is not life-saving after 20 minutes of charging, try to apply a slight pressure on the case in the contact area – sometimes they do not fit well with the charger, and check if moisture has entered the case (this can block charging).
💡
If the bracelet is not charging, try turning it over in the charger - sometimes the contacts do not match due to the production backlash.
