Xiaomi’s ecosystem has long since ceased to be associated solely with low-end devices, offering flagship solutions that are on par with market leaders. One of the key features of the premium segment was the ability to recharge the battery without using wires. Many users still wonder which models support wireless charging, since it is almost impossible to determine the presence of this feature externally.
Unlike wired connectivity, where the presence of a connector is obvious, Qi technology is hidden inside the case and requires a special induction coil. In the Redmi and POCO lines, this option is extremely rare, being the prerogative of the main brand and its top series. If you are planning to buy a new gadget or want to test the capabilities of an existing device, it is important to consider not only the fact of the feature, but also its maximum power, which can vary significantly.
The presence of a wireless interface significantly improves the ease of use of the smartphone in everyday life, allowing you to simply put the gadget on the stand in the office or car. However, it is worth understanding that the implementation of this technology in the Chinese manufacturer has its own characteristics and limitations compared to competitors. Below we will discuss in detail all current models, technical nuances and answer frequently arising questions.
The flagship series Mi and Xiaomi: the evolution of technology
It was in the flagship Mi line, and later renamed Xiaomi series, that the company first introduced support for the Qi standard. The first pioneer in this direction was the Xiaomi Mi MIX 2S, which was released in 2018. Since then, electronics manufacturers have made support for the wireless protocol a must-have for devices in the upper price segment. In newer models such as Xiaomi 13 and Xiaomi 14, the technology has been significantly improved to ensure higher speeds.
Importantly, in recent generations of flagships, the company has been focusing on proprietary fast-charging standards. If a conventional power supply delivers a standard 15W, branded stations can transmit up to 50W and even 80W of power. Reverse wireless charging has also become the de facto standard for this category, allowing you to charge headphones or watches directly from the back of your smartphone.
💡
To achieve maximum wireless charging speed, be sure to use the original Xiaomi docking station and the corresponding power supply, otherwise the speed will be limited to the Qi standard (10-15 watts).
It is worth considering that in global versions of some models, support for ultrafast protocols may be programmatically limited or require activation through special developer menus. Owners of Mi 10 series devices and newer ones are more fortunate, as they often receive updates that optimize the operation of the power module.
Xiaomi MIX series: experiments with form factor
Xiaomi MIX has always been positioned as a conceptual platform for demonstrating the latest technologies. Since the MIX 2S, all devices in the series have been equipped with a wireless charging module. Particularly noteworthy is the MIX 4, which was one of the first smartphones with a subscreen camera and a powerful power supply system. In this series, engineers have often tested new coil layouts to improve compatibility with various accessories.
A unique feature of the MIX series is the support of Mi Air Charge technology in some concepts, although it has not yet been mass produced. However, ordinary users can expect a 50-watt stub charge that is not inferior in speed to many wired analogues of the previous generation. This makes using a smartphone as comfortable as possible, since it is enough to put the device on a stand during a short conversation to get several hours of battery life.
⚠️ Attention: The use of thick protective covers or metal covers can completely block the operation of the induction coil or cause a strong heating of the device.
Owners of MIX series devices are advised to check firmware updates regularly, as Xiaomi periodically improves the temperature control algorithms for wireless charging. It is also worth remembering that when operating in the "navigation" mode with the screen on, the power replenishment speed may be lower due to security limitations.
Redmi and POCO models: are there any exceptions?
The sub-brands are not the same: Redmi and POCO’s budget policies are to cut expensive components to lower the final cost; currently, no Redmi or POCO smartphone has built-in wireless charging support, which is due to the need to save space and reduce the cost of the case.
There are third-party accessories in the form of overlay receivers connected via a USB Type-C connector that can theoretically add this feature. However, such solutions have a number of critical shortcomings, including low power transfer speed, occupied port and violation of the aesthetics of the device. For users who critically important this option in mid-range devices, the only way out is to search for models of the main brand of previous years of release.
However, some top-end Redmi Note Pro models occasionally have rumors of a possible technology introduction, but in practice they are not yet confirmed.Sub-brand engineers focus on increasing battery capacity and wired charging speed, which is often a higher priority for the target audience than the convenience of a wireless interface.
Technical standards and charging speed
Understanding technical standards is essential for the right choice of accessories: Most Xiaomi smartphones support the universal Qi standard, which guarantees compatibility with chargers from Samsung, Apple and other manufacturers. However, the maximum speed in this case will be limited to 15 watts, which is the ceiling for universal protocols.
The company’s 20, 30, 50 and 80 watt fast charging requires the use of Xiaomi’s original docking stations, which use the closed handshake protocol, which coordinates the increased voltage and current between the base and the smartphone, without this coordination, the device will go into safe mode at a minimum speed.
Below is a table with examples of wireless charging power for different generations of devices:
| Smartphone model | Max. Power (Original) | Max Power (Standard Qi) | Reverse charging |
|---|---|---|---|
| Xiaomi 13 Pro | 50 W. | 15 W. | Yes. |
| Xiaomi Mi 11 | 50 W. | 15 W. | Yes. |
| Xiaomi Mi 9 | 20 W. | 10 Watts. | Yes. |
| Xiaomi Mi MIX 2S | 10 Watts. | 7.5 Watts | No. |

How to check wireless charging support
If you already have a device and you're not sure what it's capable of, there are several ways to check it out. The most reliable way to check it is to go to the official specifications on the manufacturer's website or settings menu. Modern MIUI and HyperOS shells often have an indication of the accessory's connection.
You don't need to do this test yourself, you just need to put your smartphone back to the wireless charging on, if it supports the technology, it will emit a characteristic audible signal, and you'll see animations of the process on the screen, and in some cases, you may need to activate the function in the settings menu.
- 🔍 Go to the on charger base and touch it back of the smartphone.
- 🔍 Pay attention to the screen: should appear battery animation or a message about the start of charging.
- 🔍 Check the Settings section → Battery where wireless connection status can be displayed.
- 🔍 Use an app for diagnosis, for example, AIDA64, and see the "Power" section where the charging method is specified.
⚠️ Warning: Do not try to disassemble your smartphone to find a coil if you are not qualified.This will lead to loss of warranty and possible damage to water protection.
It is also worth considering that in some regions, versions of smartphones with reduced functionality can be sold, so when buying a device from hand or in unverified stores, it is better to rewrite the exact name of the model in advance and check its characteristics on the basis of the model. IMEI-code on the official portal.
Problems and solutions: expert advice
Despite the technology's proven provenness, users may face a number of challenges, such as slow charging or no charging, 90% of the time it is due to improper positioning or incompatible case, and the metal rings in the car are also a common cause of failure.
Another common problem is overheating. Wireless power transmission is less efficient than wired power, and some of the energy is dissipated as heat. If you notice that your smartphone is getting too hot, it's recommended to remove the case and provide additional ventilation. In hot weather, you'd better use a wired connection.
☑️ Diagnostics of charging problems
If a software failure interferes with the correct operation, reset the network settings or update the software to the latest version. In rare cases, calibrating the battery through full discharge and subsequent charging in the off state helps, but modern lithium polymer batteries rarely require this procedure.
💡
The stability of wireless charging depends on the quality of the contact platform and the absence of foreign objects between the phone and the base.
