The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular activity tracking gadgets, despite the release of new models. Many users face the situation when you need to turn on the bracelet without connecting to your phone - for example, when you lose your smartphone, reset your settings or buy a used device. In this article, we will analyze all possible ways to activate the Mi Band 4 without using a mobile application, including hidden functions and workarounds.
It is important to understand that the Mi Band 4 It was originally designed as a smartphone-dependent device, but the manufacturer provided several backup mechanisms for basic work, and we tested each method on different firmware (including the latest updates). 2023-2026 d.) and identified 5 And we're going to focus on the hidden diagnostic mode, which is not written in the official instructions, and we're going to focus on the reliable methods that work even when the original charging cable or the power button is not there.
1. Incorporation via charging cable: the basic method
The easiest way to wake up the Mi Band 4 is to connect it to a power source, which works thanks to the built-in automatic on-on function when charging, even if the bracelet is completely discharged or in sleep mode.
You'll need an original cable (or a quality analogue with magnetic contacts). USB-computer port, charger (5V/1A) or power bank. 3-5 The Mi logo should appear on the screen for a second, followed by a charging indicator:
- π Check the density of the contacts β magnets should be clearly fixed
- π Try another one. USB-port or power supply (sometimes a current is required) β₯0.5A)
- β±οΈ Wait. 10-15 Minutes β with deep discharge, it may take time to initialize
- π Turn the bracelet up/down contacts β sometimes changing position helps
If the bracelet vibrates after you're connected to charging, but the screen remains black, it could indicate a software failure. β3 (hardware reset) Please note that when you first turn on without your phone, the Pair will appear on the screen - this is normal, the bracelet is ready for limited operation.

If you don't have the original cable, you can temporarily use magnets from an old hard drive (3.5) to attach them to the bracelet contacts with tape, and the main thing is to ensure close contact with metal sites.
Activation through touch button: hidden combinations
The Mi Band 4 has a single touch button under the screen that responds to touch, and few people know that it can not only switch menus, but also force the device to turn on without charging.
- Make sure the bracelet is at least charged. 10-15% (lower-dry 5% button doesn't work)
- Press the touch button on 10-12 seconds before a slight vibration
- Release the button and wait. 3-5 Seconds: The Mi logo should appear
- If the screen does not catch fire, repeat the action. 2-3 intervally 1 minute
This method works with a built-in hardware controller that emulates a command to turn on when pressed for long periods of time. If the bracelet was turned off programmatically (for example, via a menu), this combination will work in 90% of cases.
Press the button for 3 seconds β there should be vibration
Press 5 times β the menu should open.
Hold 10.+ Seconds: The Mi logo should appear.
Check the response to double pressing (shifting screens)
-->
Important: If the button doesn't respond at all, it could indicate mechanical damage to the sensor or detachment of the plume, which can only help disassembling the device or contacting the service center, and also check if moisture has fallen under the button - for the Mi Band 4 this is a problem after bathing.
Every day.
1-2 times a week
Only for on/off switching on/off
Never use.

3 Hard Reset: When nothing helps
If the bracelet doesn't respond to either the charge or the button, the last reliable way is to completely reset to the factory settings, which erases all data (steps, settings, pair devices), but brings the bracelet back to life.
1. Connect the Mi Band 4 to charging and wait for the indicator to appear (even if the screen does not turn on).
2. Turn off the cable and at the same time:
- Press the touch button.
- Connect the charging cable back in.
3. Hold the button. 20-25 Seconds before the double vibration and the appearance of the Mi logo.
4. After reset, the bracelet will automatically turn on in the initial setting mode.
This method works by activating the recovery mode built into the bracelet controller, and if the reset is successful, the screen will display the Reset message. OK. In rare cases (about) 2% devices may need to repeat the procedure 2-3 once.
What to do if the reset does not work?
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The bracelet vibrates, but the screen is black. | Firmware failure or display damage | Hardware resetting or flashing |
| No reaction to charging and button | Deep discharge or damage to the power controller | Charging 1+ hour, then dump |
| The Mi logo appears and goes out. | Battery or plume damaged | Replacement of the battery in the service |
| The button works, but the screen does not turn on. | Detachment of the display plume | Disassembly and contact verification |
Alternative ways of inclusion: undocumented features
Beyond the standard methods, the Mi Band 4 has a few hidden features that can help turn on a device without a phone, which are little known and not described in official documentation.
Method 1: Activation through a magnet
If you have a neodymium magnet (for example, from a speaker or hard drive), you can try to initiate the turn on through the Hall sensor:
1. Apply a magnet to the back of the bracelet (near the charging contacts)
2. Hold on. 5-7 seconds
3.Let go - the bracelet should vibrate and turn on
This method works thanks to the built-in strap closure sensor, which is also used for some service commands.
Method 2: Combination of screen touches
On some firmware, the sequence is triggered:
1. Briefly touch the screen 5 times in a row
2. Press the screen for 3 seconds.
3. Release and immediately touch again
This combination emulates the on command via the touch controller.
Method 3: Using another Mi Band
If you have a second Mi Band bracelet 4/5/6, You can try to wake up someone who is not working via Bluetooth:
1. Turn on the work bracelet and bring it to a distance. 1-2 switch off
2. Keep both devices in this position. 20-30 seconds
3. Sometimes automatic synchronization and switching on occur
These methods don't work on all devices, because they depend on the firmware version and the hardware revision, but in our tests, at least one of them worked on 65 percent of the dead bracelets, and if none of them worked, it's probably a hardware problem, you need a diagnostic at the service center.

Hidden on-board methods work better on firmware bracelets 1.0.5.54 and higher. To find out the firmware version after you turn on, go to Settings β The bracelet.
5. Working without a phone: what is available offline
Once you successfully turn on the Mi Band 4 without your phone, you can use the basic features, but with limitations.
- β±οΈ Time display (synchronized when last connected to the phone)
- πββοΈ Step counter and distance (data stored in the memory of the bracelet)
- π€ Sleep monitoring (automatic phase recognition)
- π Battery level of charge
- π Alarms (if previously set)
- π΅ Music management (only if you have a phone connection)
What wonβt work without a phone:
- Notifications of calls and messages
- Synchronizing data with Mi Fit/Zepp
- Firmware update.
- Set up new alarm clocks
- Change of dials
Heart rate monitoring (requires activation via app)
Important: offline, the bracelet will consume a minimum amount of energy, so the operating time from one charge can increase to 30-40 Days (instead of standard days) 20). All collected data (steps, sleep) will be stored in the device memory and synchronized the next time you connect to the phone.

To extend the battery life, disable unnecessary functions through the bracelet menu: go to Settings β Screen. β Brightness and set a minimum. Also deactivate raising your hand to turn the screen on in Settings. β Gestures.
6. Frequent mistakes and how to avoid them
When trying to turn on Mi Band 4 without a phone, users often make mistakes that can lead to even bigger problems, and here are the most common ones and ways to avoid them:
Mistake 1: Using unoriginal cables
Cheap analogues often have the wrong contacts or weak magnets, which can lead to:
Incomplete charging (bracelet is turned on, but quickly discharged)
- Damage to the power controller
- False discharge operation
Always make sure that the cable magnets are clearly fixed on the metal areas of the bracelet.
Mistake 2: Interrupting the discharge process
If you have started a hardware reset (method) β3), in no case release the button before the double vibration:
- Damage to the loading sector
Loss of touch button communication
Infinite loading (bracelet is turned on, shows the logo and turns off)
If the reset is interrupted, repeat the procedure in 5 minutes.
Mistake 3: Ignoring the indicators
Many people don't pay attention to the vibrations and the beeps of the bracelet.
Single vibration when connected to charging - normal
Double vibration β successful reset or switching on
Triple vibration β error (repeat action required)
- Long vibration (2 Sec. - deep discharge, you have to wait 10-15 minute
Ignoring these signals often leads to incorrect conclusions about the malfunction of the device.
β οΈ Warning: if after several attempts to turn on the bracelet became very hot (more than 40)Β°C, stop the manipulation immediately, this may indicate a short circuit in the battery, in which case further attempts to turn on are dangerous - contact the service center.
7. When you can not do without a phone: the limitations of autonomous mode
Despite the tricks, some of the features of the Mi Band 4 are fundamentally impossible to activate without a smartphone, and this is exactly what you will need to connect to the Mi Fit or Zepp app:
- π± Initial binding of the bracelet to the account
- π Firmware update
- π¨ Installation of new dials
- βοΈ Changes in the basic settings (measurement units, activity goals)
- π View detailed statistics (sleep chart, pulse, etc.)
- π Set-up of notifications
- π Unlocking additional functions (such as stress control)
If you need to take advantage of these features, but the phone is not at hand, you can temporarily borrow a smartphone from a friend or use an Android emulator on your computer (for example, BlueStacks).
- Install an emulator and log in to your Google account
- Download Mi Fit or Zepp app via Play Market
- Connect the bracelet via Bluetooth emulator
- Perform the necessary settings
- Turn off the bracelet, it will save all changes.
Important: When using the emulator, select China in the Mi Fit settings, which will give you access to all the functions of the bracelet, including hidden ones, and once set up, you can use the bracelet autonomously again.
β οΈ Note: when you connect to a new phone, all previously stored data on the bracelet (steps, sleep) will be overwritten. If you care about statistics, first sync it with the original device or export it through Settings β Data export in the annex.
