How to turn off Xiaomi Mi Band 4: all the ways and nuances

The Xiaomi Mi Band 4 fitness bracelet has become one of the most popular wearables due to its functionality and affordable price. However, many users have difficulty trying to completely turn off the gadget - there is simply no standard "Switch off" option on the menu. This is due to the peculiarities of energy saving the device: the manufacturer optimized the bracelet so that it consumes minimal energy in standby mode.

In this article, we will discuss all possible ways to disable the Mi Band 4, including software reset, physical shutdown and alternative methods. You will learn how to properly turn off the bracelet without risking damaging it when it is really necessary, and what to do if the device does not respond to commands.

Why is there no off button in Mi Band 4?

The concept of permanent operation is embedded in the architecture of most Xiaomi fitness bracelets. Unlike smartphones, where the user is accustomed to completely disabling the device, wearable electronics are designed for round-the-clock use.

• 🔋 Energy efficiency: In standby mode, the bracelet consumes everything ~5% charge per month, so it makes no sense to turn it off.
• ⏱️ Continuous monitoring: Disabling will interrupt the collection of data on sleep, pulse and activity, which contradicts the main task of the gadget.
• 🔄 Quick start: Mi Band 4 system optimized for instant wake-up when raising your hand or pressing the sensor.
• 🛠️ Failure protection: Frequent on/off can damage flash memory where firmware and settings are stored.

However, there are situations where it is necessary to turn off the bracelet: flashing, long-term storage (more than 3 months), resetting to factory settings or eliminating software glitches, in which alternative methods are used, which will be discussed later.

Method 1: Software reset via the bracelet menu

The safest method of shutting down is factory reset, which simulates shutdown, but actually returns the device to its original state, and Importantly, after that procedure, all the data on the bracelet (except the statistics in the Mi Fit app) will be deleted.

Step-by-step:

1. Check the battery charge – it must be at least 50%, otherwise the reset may be interrupted.
2. On the bracelet, scroll down to the optional item (three-point icon).
3. Select Resetting (circle arrow icon).
4. Confirm the action by clicking the tick. The bracelet vibrates and reboots.

Once reset, the bracelet will remain inactive until you reconnect it to the Mi Fit app.This is as close to “turning off” as all functions except the basic time display are turned off.

Charge the bracelet to 50%+

Unconnect from the account in Mi Fit (optional)

Save sleep/activity data in the appendix

Make sure there are no magnets nearby (may prevent the reset)

⚠️ Warning: If the bracelet does not turn on after 10 minutes, connect it to charge.

Method 2: Physical power outage

If the bracelet is stuck or not responding to the sensor, you can force the power to turn off, simulating the extraction of the battery.

1. Remove the strap from the body of the bracelet, pulling it towards the screen.
2. Carefully tuck the back cover (it holds on the latches). Use a plastic shoulder blade or mediator to avoid damaging the body.
3. Disconnect the battery plume from the motherboard for 10-15 seconds, just slightly lift it with a nail or blunt side of the shoulder blade.
4. Put the bracelet back together.

This method is guaranteed to zero out all the temporary data in the bracelet memory, including interface glitches, but it requires caution: if you handle it sloppy, you can damage the battery plume or contacts.

Method 3: Battery discharge before complete shutdown

If you need to turn off the bracelet for a long time (for example, during a vacation), you can wait until it is completely discharged.

• 🔌 Turn off notifications in the Mi Fit app to reduce power consumption.
• 📵 Turn off the permanent pulsemeter in the bracelet settings (Profile) → Heart monitoring → Off.).
• ⏳ Leave the bracelet alone for 2-4 days. It automatically shuts down when it reaches 0%.

After such a disconnect, the bracelet can be stored for up to 6 months without the risk of damage to the battery.

⚠️ Warning: Do not leave the bracelet discharged for longer than 6 months - this can lead to irreversible loss of battery capacity.

💡

If you need to speed up the discharge, turn on the bracelet maximum brightness of the screen (Settings → Display → Brightness → 5) and activate constant lighting (Settings → Display → Backlight → Always).

Method 4: Disconnect via firmware (for advanced)

For power users, there is a method of forced shutdown through firmware, which is suitable if the bracelet is getting stuck in a reboot cycle or does not respond to the sensor.

• 💻 Windows computer 7/10/11.
• 🔌 Firmware cable (e.g. Mi Band 4) USB dongle).
• 📁 Firmware and utility MiBand4Tools (You can download it on the forum 4PDA).

Algorithm of action:

1. Connect the bracelet to your computer via an adapter. Drivers must install automatically.
2. Start MiBand4Tools and select Reboot to Fastboot.
3. In the command line, type: fastboot oem off-mode-charge 0 This will turn off the bracelet before connecting to charging.

This is a risky way to make a mistake, and if you make a mistake, you can turn the bracelet into a brick, and only use it if other methods have failed.

💡

Firmware through a PC is the last resort, and 90 percent of the time, a menu reset or battery shutdown is enough.

What if the bracelet does not turn on after switching off?

If you don’t show signs of life after any of the procedures described, follow these steps:

1. Check the charging: 🔌 Connect the bracelet to the original cable and power adapter 5V/1A. 🕒 Wait a minute. 30 Minutes – sometimes the charging indication does not appear immediately.
2. Reset the settings forcibly: 🔄 Press the touch button for 20 to 30 seconds. Vibration signals reset.

Check the contacts.

• 🔍 Look at the charging connector on the bracelet, and it's possible that there's dirt or contacts that have become oxidized.

If the bracelet is still not turning on, the problem may be a damaged firmware or a faulty battery, in which case contact the Xiaomi service center or try to reflash the device yourself (see method 4).

Frequent Mistakes and How to Avoid Them

When trying to turn off the Mi Band 4, users often make critical errors that can disable the bracelet.

• ⚡ Use of non-original chargers: Cheap cables can deliver unstable voltages, causing the power controller to fail.Always use the original Xiaomi cable.
• 🧲 Storage near magnets: Strong magnetic fields (such as from speakers or smartphone chargers) can knock down the bracelet compass and cause occasional reboots.
• 💦 Contact with moisture during disassembly: Despite water protection 5 ATM, When opening the body, avoid getting liquid on the board.
• 🔥 Overheating when firmware: If the bracelet is heated above 40°C during flashing, immediately disconnect it from the PC and let it cool down.

To minimize risks, always back up your data in the Mi Fit app before any manipulation of the bracelet. To do this, go to Profile → Settings → Backup.
