Wireless power transmission technology has ceased to be exclusively a luxury flagship, gradually penetrating the middle market. For owners of the Xiaomi ecosystem, this is especially true, as the company is actively implementing standards for fast wireless charging in its top devices. Many users still mistakenly believe that all modern phones can charge from magnetic fields, but this is not true.
Engineers are introducing inductance coils inside the case, which requires additional space and a complex cooling system. That’s why supporting this feature often becomes a watershed between budget and flagship models. Understanding which Xiaomi smartphones support wireless charging will help avoid buying unnecessary accessories.
In this article, we will discuss in detail the list of compatible devices, the technical nuances of the Qi standard and the features of proprietary acceleration technologies. You will learn why some models charge faster than others and how to choose the right back-charging power bank.
Principle of operation and standards of wireless energy transmission
The basis of the technology is electromagnetic induction, discovered in the XIX It's a very big thing, but it's only now, and it's based on the transfer of energy between two coils, one in a charger (transmitter) and one in a smartphone (receiver). As the alternating current passes through the transmitting coil, a magnetic field is created that induces current in the receiving coil of the phone.
Xiaomi uses the universal Qi standard developed by the Wireless Power Consortium, which means you can charge your smartphone on any certified site, whether it is a car holder or a station from another brand.
- ⚡ The standard charging speed of Qi is usually 5-10 Watt.
- ⚡ Xiaomi’s proprietary technologies allow you to reach power of 30, 50 and even 80 watts.
- ⚡ To work at high speeds, accurate centering of the coils and active cooling are required.
It is important to understand that Xiaomi’s high-speed contactless charging requires a complex temperature management system. When transferring high power, a significant amount of heat is released that can degrade the battery. Therefore, the Mi and Xiaomi flagships use special graphite layers and fans in charging stations.
💡
Use Xiaomi’s original charging stations to get the claimed top speed, as third-party devices are often limited to the 15W standard.
Full list of Xiaomi smartphones with wireless charging support
To determine whether your gadget supports this feature, you can only know the exact model. Engineers do not always include this feature in mid-range devices, leaving it a privilege of flagships. Below is the current list of devices, divided into series for convenience.
The Mi series (now renamed Xiaomi with a numerical index) traditionally gets the best technology. Since the Mi 9, wireless charging has become the standard for top-end lines. At the same time, the Redmi Note series and Redmi budget models are most often deprived of this option in favor of lower cost.
| Series | Models. | Max. Power (Original) | Max. power (Qi) |
|---|---|---|---|
| Xiaomi (Mi) | Mi 9, Mi 10, Mi 11, Mi 12, Mi 13, Mi 14 | 20-80 W. | 10-15 W. |
| Mi Mix | Mi Mix 3, Mi Mix 4 | 30-50 W. | 10-15 W. |
| Xiaomi Ultra | 12S Ultra, 13 Ultra, 14 Ultra | 50 W. | 15 W. |
| Black Shark | Black Shark 3 Pro, 4 Pro, 5 Pro | No. 15-25 W. | 15 W. |
It’s worth noting that Black Shark’s gaming smartphones, which are a sub-brand, also have support for this feature in older models, which allows gamers to use magnetic coolers with a charging function, which is much more convenient than constantly connecting the cable while playing.
Air Charge and Mi Turbo Charge
Xiaomi has not stopped at the basic standard and developed its own acceleration protocols, Mi Turbo Charge technology allows you to transfer power with a power of up to 80 watts, which is comparable to the speed of a wired connection, but it requires a special adapter and cable, as well as a compatible charging station.
The Mi Air Charge is a revolutionary technology that allows devices to be charged several meters away without physical contact with the site. Although mass adoption in consumer devices has not yet occurred, prototypes demonstrate the ability to charge multiple gadgets simultaneously within a room.
⚠️ Attention: High Power Protocols (50 Watts and above) work only with original Xiaomi chargers. When using third-party sites, power will be limited to the basic standard. 5-15 Watt.
Realizing these speeds requires two-way communication between the charger and the smartphone. The charging processor constantly monitors temperature and voltage, dynamically changing the current parameters. If you use a case that is more than 3 mm thick or with metal elements, the charging efficiency can drop dramatically.
Why does wireless charging heat up your phone?
Reverse wireless charging: how to charge other devices
Many of Xiaomi’s flagship models have a reverse charge feature, which means your smartphone can work as a powerbank for other Qi-enabled gadgets. You can put Mi True Wireless headphones, smartwatches, or even another smartphone on the back of your phone.
To activate this function, you need to go to settings. Usually the path is: Settings → Battery → Reverse wireless charging. Once turned on, just put the compatible device to the center of the back of your phone, and the indicator on the screen will show the process of power transfer.
- 🔋 Recharge speed is usually limited to 10 watts to protect the battery.
- 🔋 The function automatically shuts down if the charge of the main device drops below. 20-30%.
- 🔋 Metal rings on covers can block energy transfer.
This feature is extremely useful in emergency situations when you need to recharge your headphones and the sockets are not at hand, but you should not use the phone as the main power source for other devices, as this causes heavy heating and wear of the battery.
💡
Reverse charging is an emergency tool for small devices, not a replacement for a full power bank for daily use.
Compatibility issues and the impact of covers
One of the most common problems users have is the inability to start the charging process. Most often, protective accessories are the culprit. Magnetic rings, car holders attached to the rear panel, and thick rubberized cases increase the distance between the coils, which is critical for induction.
If you carry your phone in a tight case, Xiaomi’s wireless charging may not work stable or start at all.The optimal thickness of the third-party case should not exceed 2-3 mm. Metalized elements, magnetic-protected card pockets are also an obstacle.
⚠️ Warning: Never put metal objects (keys, coins, paper clips) between your phone and the charging pad, which can heat up to high temperatures and damage the charging surface or the case of your smartphone.
The coil in Xiaomi smartphones is often shifted relative to the center, closer to the logo or cameras. If the phone is lying wrong, charging can be constantly turned on and off, which is harmful to the power controller.
Comparison of wired and wireless charging: pros and cons
Despite the convenience, the technology has its limitations compared to traditional cable, and the main advantage is that the USB-C connector does not wear mechanically. Thousands of cycles of connecting and disconnecting the cable loosen the socket, leading to poor contact. Contactless method completely eliminates this factor.
On the other hand, the efficiency of wireless power transmission is lower: some of the electricity is lost as heat, which makes the process less environmentally friendly and longer if you don't use proprietary fast stations, and you can't comfortably use the phone in your hands while charging, as you would with a long cable.
☑️ Check before buying charging
For an office desk or bedside table, wireless charging is ideal: you put your phone down and forgot. For fast charging on the run or while navigating in the car, cable is still a more efficient solution, especially given the high power consumption of modern screens.
