Wireless charging on Xiaomi smartphones is a convenient feature that eliminates the confusion of wires and prolongs the life of the connector USB-C. But what if suddenly stopped charging without a wire? The problem can be both banal inattention (incorrect position on the station) and serious hardware malfunctions (failure of the coil or power controller). In this article, weโll break down all the possible reasons why wireless charging doesnโt work on Xiaomi, from Mi 11 models to Redmi Note 12 Pro.+, We also provide step-by-step instructions for diagnostics and repairs.
Itโs important to understand that not every Xiaomi model supports wireless charging. 10/12 or POCO M5 This function is not used, whereas flagships (Xiaomi) 13 Ultra, Mix Fold 3) equipped with fast wireless charging power up to 50 If your device does not initially support Qi technology, no manipulation will make it charge "over the air." First check the specifications of your model on the official Xiaomi website or in the documentation.
If the function is supposed to work, but the smartphone stubbornly ignores the charging station, we start looking for the problem, and let's start with the simplest and most obvious reasons, and then move on to the complex technicalities.
1. Verification of compatibility of device and charging station
The first thing to do is make sure your charging station is compatible with the Xiaomi model. Not all wireless charging is the same: they differ in power, standards (Qi, PMA, AirFuel) and even the location of the coil. For example, the Xiaomi 12 Pro smartphone supports charging up to 50 watts, but only with the original Mi Wireless Charging Stand. If you use cheap nameless charging with AliExpress, it may simply not be able to handle the right current.
How to check compatibility:
- ๐ฑ Smartphone model: Check on Xiaomiโs website or documents to see if your device supports wireless charging, POCO F5 It doesn't have one, but Xiaomi. 13T Pro - supports.
- โก Station power: Compare the charging power (indicated on the case or in the instructions) with the maximum power that the smartphone supports. 11T Pro is 120 watts over wire and 50 watts over air.
- ๐ Qi standard: Make sure the station supports Qi 1.2.4 or higher.Older versions may not recognize new smartphones.
If you use charging from another brand (like Samsung or Apple), it may work, but with less power or unstable. Xiaomi's original accessories are usually optimized for their own devices.
2. Incorrect position of the smartphone at the station
One of the most common reasons wireless charging doesn't work is because the device is in a wrong position on the station. Qi requires the exact alignment of the transmission and reception coils, so if the smartphone is lying curved or shifted relative to the center, the charging will either not start or will be interrupted.
How to properly place the smartphone:
- ๐ฏ Center to center: The coil in the smartphone is usually located in the center of the back panel.
- ๐ Distance: Maximum distance between the coils is 5-8 mm. If the smartphone has a thick case or sticker, remove them.
- ๐ Orientation: Some models (e.g. Xiaomi Mix 4) are rotating sensitive.Try to turn the device around at 90ยฐ 180ยฐ.
If you have an indicator (LED or sound signal) at the station, it will help you navigate. For example, on the Mi Wireless Charging Pad, a white LED lights up when you successfully connect, and if the indicator flashes or burns in red, the position is incorrect.

3. Problems with cover, stickers or magnetic fastenings
Cases, protective glass and magnetic holders can block the wireless charging signal, especially for:
- ๐ก๏ธ Metallized covers (with aluminum or steel inserts).
- ๐งฒ Magnetic holders (for example, for fastening in a machine).
- ๐ Thick silicone or armored cases (more than 3 mm thick).
- ๐ณ Card Holders with Metal Clamps for Bank Cards.
The solution is simple: remove the case and all accessories before charging. If the problem is gone, look for an alternative case marked "Qi-compatible." For example, the original Xiaomi cases for the Mi 11 Lite or Redmi. K50 usually do not interfere with charging.
Also check the back of the smartphone for metal stickers (such as from previous cases) or damage. scratches on the glass panel usually do not affect, but cracks can disrupt the coil.
Why do magnets interfere with charging?
4. Software failures and MIUI errors
Sometimes wireless charging doesnโt work due to software errors in the firmware MIUI. This can happen after you update the system, reset your settings, or install custom firmware:
- ๐ Charging begins, but is interrupted after a few seconds.
- ๐ฑ Smartphone vibrates when placed on the station, but the charge does not go.
- โ ๏ธ Notification: "Charger not supported".
How to fix software problems:
- Reboot your smartphone. It's banal, but it often helps.
- Reset charging settings: Go to Settings โ Battery and productivity โ Battery settings. Find "Reset Charging Settings" (may be called "Optimize Charging"). Confirm the reset.
- Update MIUI: Go to Settings โ About Phone โ System Update and install the latest firmware version.
- Reset network settings: Sometimes failures are related to power management. โ SIM-maps and mobile networks โ Resetting network settings.
If the problem occurs after the update MIUI, Try to roll back on the previous version (if backup is available) or wait for a patch from Xiaomi.Relatively, a full reset helps (but remember to back up your data!).

After the update MIUI If you're charging wirelessly, you're not stable, try turning off Adaptive Charging in your battery settings. Sometimes optimization algorithms conflict with wireless protocols.
5. Hardware malfunctions: coil, controller, battery
If all previous steps have failed, the problem is likely hardware.The wireless charging in Xiaomi smartphones depends on several components:
- ๐ Receiver coil (located under the back panel).
- ๐ Wireless charging controller (part of motherboard).
- ๐ Battery (if it is swelled or worn out, it can block charging).
- ๐ถ Trains and contacts (damage after falls or repairs).
Diagnostics of hardware problems:
| Symptoms. | Probable cause | Decision |
|---|---|---|
| Charging does not start at all, the indicator at the station does not respond | Receiver coil or controller is faulty | Replacement of the coil or repair of the motherboard |
| The smartphone is heating up, but not charging | Short circuit in the coil or battery | Diagnostics at the service center |
| Charging is only in a certain position. | The coil plume is damaged or it is displaced. | Coil-sweetening or re-coil replacement |
| The smartphone charges, but very slowly (1-2 watts) | Battery wear or controller failure | Replacement of the battery or the firmware of the controller |
Self-repair of hardware faults is not recommended if you do not have experience with electronics. Disassembly of a smartphone without special tools can damage the plumes or motherboard. Contact the authorized service center Xiaomi will diagnose and replace the faulty components with a warranty.

If the smartphone fell or was exposed to moisture, hardware malfunction is almost guaranteed.Wireless charging is particularly sensitive to mechanical damage due to the fragility of the coil and plumes.
6.Problems with charging station or power cable
It's not always the smartphone that's to blame, because often the problem lies in the charging station or the power station.
- ๐ Power Cable: Use Xiaomiโs original fast charging cable (e.g., fast charging, USB-C to USB-C). Cheap cables may not provide enough current.
- โก Power supply: The station must be connected to a power supply unit with a capacity of at least 18 W (for charging 30-50 W need a unit of 65 W).
- ๐ Port port USB: Try connecting the station to another port or charger.
- ๐งน Contact pollution: Dust or oxidation on station connectors may disrupt contact.
How to test the station:
- Connect the station to another Qi-enabled smartphone (like an iPhone or Samsung Galaxy). If it charges, your Xiaomi is a problem.
- Try another socket or USB-Sometimes it's the fault of an unstable network.
- Check the station for damage: cracks, melts or foreign smells (burnt plastic).
If the station does not work with any device, it will have to be replaced. Xiaomiโs original stations last longer, but also cost more (from 2,000 to 5,000 rubles), Budget analogues can be found for 500-1 500 rubles, but their reliability is lower.

If the charging station is warming up or is making a high-frequency squeak, immediately disconnect it from the mains! These are signs of malfunction that can lead to fire.
7. Effects of Temperature and Humidity on Wireless Charging
Wireless charging is sensitive to temperature, and if a smartphone or station overheats, the system automatically turns off charging to protect the battery, which can occur in the following cases:
- โ๏ธ Heat: Temperatures above 35ยฐC (for example, if the smartphone was lying in the sun or in the car).
- โ๏ธ Cold: Temperatures below 0ยฐC (the battery may be temporarily disconnected).
- ๐ฆ Humidity: Condensation or liquid entering the contacts.
- ๐ฅ Intense load: Simultaneous charging and playing heavy games (Genshin Impact, Call of Duty Mobile).
How to solve the problem:
- Let your smartphone cool to room temperature (20โ25)ยฐC).
- Do not use wireless charging during games or video processing.
- Make sure the station is in a ventilated place (not on a soft surface that blocks the heat sink).
- If your smartphone overheats regularly, check the cooler (on Black Shark gaming models) or replace the heatpaste (at the service center).
If your smartphone shows a warning โBattery temperature is too highโ or โCharging is suspendedโ, do not try to bypass the protection โ this can lead to bloating of the battery or even fire.
8.When to contact the service center
If you've tried all the ways, but wireless charging still doesn't work, it's time to contact a specialist. Here are signs that repairs are necessary:
- ๐ง The smartphone is not charged from any wireless station, but normally charges over a wire.
- โก On the screen appears the error "Wireless charging malfunction" or "Refer to the service".
- ๐ฅ Smartphone gets too hot or shut down when trying wireless charging.
- ๐ฅ There were physical injuries: falls, moisture, repairs with disassembly.
Where to repair:
- Official Xiaomi service centers: Warranty repair (if the device is warranty) or paid diagnostics. mi.com/ru/service.
- Authorized partner workshops: Often cheaper than official service, but with a guarantee for work.
- Unofficial workshops: Risky - you can run into unqualified craftsmen or fake parts.
The cost of repair depends on the problem:
- Replacement of the coil of wireless charging: 1,500โ3,000 rubles.
- Repair/replacement of the power controller: 3000-6000 rubles.
- Battery replacement: 2,000โ4,000 rubles (original battery).
If the smartphone is warranty, do not disassemble it yourself - this will void the warranty. Xiaomi service center must diagnose and fix the malfunction free of charge (unless it is caused by mechanical damage).
