Xiaomi smartwatches are some of the most popular wearables on the market, but even they are not immune to failure.The situation when the Mi Band or Mi Watch stops turning on is familiar to many users. The reasons can range from banal battery discharge to serious hardware malfunctions. In this article, we will discuss all possible scenarios why your gadget does not respond to the on button, and what to do about it.
It's important to understand that the algorithm of actions depends on the model of the device. 6 Mi Watch Lite and Mi Watch Lite have different reset schemes, and Xiaomi Watch S1 It requires a special approach because of the built-in eSIM. We will take these nuances into account and give universal recommendations applicable to most line devices. Mi/Wear.
If your watch doesn't show signs of life (it doesn't vibrate, doesn't light up, doesn't react to charging), don't rush to carry it to the service center. In 80% of cases, you can solve the problem yourself in 10 to 30 minutes. The main thing is to correctly diagnose the cause.
1.Discharged battery: the most obvious cause
The first thing you need to check is the battery level, and even if you're sure you charged the clock the day before, the battery might have run out because of:
- π Deep discharge β if the device has been lying for a long time without recharging (more than 2-3 weeks), the power controller can block the current supply.
- π Faulty cable/adapter β cheap non-original charging often doesnβt provide enough current.
- β‘ Software failure β sometimes the system incorrectly displays the charge level (for example, shows 20%, although the actual 0%).
To rule out this cause:
- Connect the watch to the original charger (use the cable from the kit).
- Leave at least 30-40 minutes on charge, even if there is no reaction. Deep-discharge devices may not wake up right away.
- Check the indication: the Mi Band should light up red/green LED, the Mi Watch should appear battery icon.
If you don't have a charging reaction after an hour, move on to the next step: Don't use "fast" smartphone charging - it can damage the watch battery due to improper voltage.

On models Mi Band 7 and newer at deep discharge helps to connect to charging through USB-Hub (not directly to the socket) This resets the power controller.
2. Problems with charger or cable
About 30 percent of the calls to service centers involve faulty accessories, and even if the cable looks good, the wires may have been worn or the contacts oxidized inside.
- π Try another cable β preferably original from Xiaomi or certified (marked) 5V/1A).
- π Use another power adapter - charging from a smartphone with an output will suit 5V/2A.
- π Check the contacts on the watch and cable: they should be clean, free of oxidation or contamination.
Pay special attention to the magnetic contacts on the Mi Band, which can demagnetize or become contaminated with potassium fat deposits over time, wipe them with an alcohol napkin and check the density of the cable.

Check the charging indication in 30 minutes-->
If the watch starts to warm up when you connect to charging, but does not turn on, this is a sign of a short circuit in the battery, in which case you can not continue charging, as this can lead to fire.
3. Software failure: when the clock "hangs"
Xiaomi smart watches work on the base RTOS or OS (They're new models, and like any operating system, they can crash:
- π₯οΈ The clock vibrates when you press a button, but the screen does not turn on.
- π The device loops on the Mi logo when turned on.
- π± Application Mi Fitness/Zepp does not detect the device.
To reset settings, use hardware reboot:
- Connect the watch to the charger (required!).
- Press the power button for 15-20 seconds (on the Mi Band β the touch area under the screen).
- If the screen flashes or the logo appears, release the button. The watch should reset.
For Mi Watch models (e.g., for example, S1 Pro) the process is more complicated:
- Press and hold both buttons (power) + bottom) within 10 seconds.
- After vibration release the buttons - the watch will reset to the factory settings.
What if the reset didn't help?
Once reset, the watch will lose all data (steps, pulse, settings), but it's better than a broken device. If the reset didn't work, it's more of a hardware problem.
4. Hardware malfunctions: when without repairs can not do
If all the previous methods didn't work, it's probably a physical breakdown.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The watch does not respond to charging, does not warm up. | Power supply circuit break, faulty charge controller | Replacement of food (in the service) ~1500β2500 β½) |
| The screen flashes, but the image is missing. | Detachment of the display plume or failure of the matrix | Snap-steeling or screen replacement (~2000β3500 β½) |
| The clock is on, but it's off. | Failure of the battery (swelling, short circuit) | Battery replacement (~1000β2000 β½) |
| Vibration's working, screen's gone. | Damage to flexible display cable | Diagnostics in the service (repair or replacement is possible) |
The most common hardware problem is a bloated battery, and you can recognize it by the following signs:
- π The body of the watch is deformed (bulges on the back cover).
- β οΈ When charging, there is a smell of fire.
- π₯ The watch heats up even without a charger connection.
β οΈ Attention! If the battery is swelling, you can't keep using the watch, it's dangerous! Lithium batteries can ignite if damaged.
The cost of repair depends on the model:
- π° Mi Band 5/6 β battery replacement will cost 800β1500 β½.
- π° Mi Watch Lite β Screen or board repair ~ 2000β3000 β½.
- π° Xiaomi Watch S1 β Due to the complex design, repairs can cost 3,500-5,000 β½.
5. Problems after firmware update
Firmware updates should improve the operation of the device, but sometimes they lead to "bricking" (complete loss of functionality).
- π± Interrupted updates (for example, if the clock is running out during the process).
- π Incompatible version of the software (if you manually stitched the wrong firmware).
- π§ Communication failure between the watch and the smartphone during data transfer.
If the watch stops turning on after the update, try the following steps:
- Connect the watch to charging and leave for 1-2 hours (sometimes the system is restored by itself).
- Perform a forced reset (see Section 3).
- If the screen shows an Error 102 or Bootloop error, you will need to flash through Fastboot.
For manual flashing:
- Download the official firmware for your model from the Xiaomi website.
- Use the MiFitTool utility or ADB software installation.
- Follow the instructions for your model (the Mi Band and Mi Watch are different!).
β οΈ Attention, the wrong firmware can permanently damage the watch, and if you're not sure what you're doing, you should contact the service center, especially with Wear models. OS (Xiaomi Watch S1/S2), where recovery is more difficult.
External factors: water, falls, overheating
Xiaomi smart watches have different levels of protection from moisture and dust:
- π§ Mi Band 5/6/7 β 5 ATM (You can swim, but you can't dive deeper. 50 ).
- π§ Mi Watch Lite β IP68 (protection against splashing and short-term immersion).
- π§ Xiaomi Watch S1 β 5 ATM, But with a reservation: not for hot water (shower, bath).
If the watch is stopped after contact with water:
- Remove them immediately from the water and turn them off (if they react).
- Dry for at least 24 to 48 hours in a dry place (do not use a hair dryer or microwave!).
- Place in a silica gel bag (eat in shoe boxes or electronics).
- Do not try to turn on until you are sure that the inside is dry.
Signs of water damage:
- π Under the screen, drops or condensation are visible.
- π The watch does not hold charge (water oxidizes the contacts of the battery).
- π± The touch screen does not respond or is triggered spontaneously.
If the clock falls from a height, check:
- π₯ Integrity of the body β cracks on the screen or back cover.
- π§ Power button β it could have drowned or broken.
- π‘ antenna Bluetooth/Wi-Fi (model GPS) β Falling down may damage the communication module.
π‘
Even if the watch has 5 protections ATM, Avoid prolonged exposure to chlorinated water (pool) or salt water (sea) β this shortens the life of seals and can lead to corrosion of contacts.
7. When to contact the service center
If you have tried all the methods, but the watch is still not turned on, it is time to contact the professionals.
- π§ Physical damage to the board (visible burns, chips, detached elements).
- π Bloated battery (see section 4).
- π₯οΈ bootloader errors (the screen displays Error 101, Boot Failed codes).
- π‘ Problems with the communication module (the clock is not determined by any device).
Where to repair:
- π’ Official service centers Xiaomi - warranty repair (if the device is warranty) or paid.
- π§ Unofficial workshops are cheaper, but the risk of running into poor-quality repairs!
- π Electronics stores (for example, Svyaznoy, M.Video) - some have their own service centers.
The cost of repair in the official service (about):
