Owners of modern Xiaomi smartphones often wonder how to activate wireless charging, not realizing that in most cases this process does not require complex configuration. The Qi technology used in devices implies complete automation: the user just needs to put the gadget on a compatible platform. However, there are nuances associated with reverse power mode and fault diagnosis that require intervention in the settings of the system.
First of all, you need to clearly understand the difference between receiving energy and transmitting it. If your smartphone only supports reception, then turning on the function boils down to buying the right station. In a situation where the device should work as a powerbank for other gadgets, you will need to activate a special mode in the settings menu. Reverse wireless charging on Xiaomi is often turned off by default to save battery power.
In this article, we will take a detailed look at the algorithms for different use cases, check the compatibility of models and eliminate possible errors, learn why the indicator may not light up and what parameters affect the power transfer rate, and this guide will help you to make the most of the capabilities of your Redmi or Poco.
Technical support of the function in the model
The first and most critical step is to verify that you have the right hardware inside your device, and many users mistakenly assume that if your phone looks modern and has a glass back, it has wireless charging, and in fact, the induction coil is only installed in flagship models and some mid-range devices.
To accurately determine the capabilities of your gadget, it is recommended to consult the official specifications on the manufacturer's website or check the technical data in the system menu. Lack of support at the hardware level cannot be corrected by software methods or firmware updates. Attempts to use external receivers in such cases can lead to unstable operation or overheating.
Below is a table that helps you quickly navigate the technology support among the brand’s popular lines.Please note that having a glass panel is not a guarantee of functionality.
| Series of devices | Admission support (Qi) | Support for impact (Reverse) | Maximum power |
|---|---|---|---|
| Xiaomi Mi 9 / 9 Pro | Yes. | Yes. | 20 W/10 W/ |
| Xiaomi 13 / 14 Series | Yes. | Yes. | 50 W/10 W/ |
| Redmi Note 12/13 | No. | No. | — |
| Poco F5 / F6 | No. | No. | — |
| Xiaomi Mix Fold | Yes. | Yes. | 50 W/10 W/ |
If your model is not on the list or it belongs to the budget segment, most likely, the hardware for inductive charging is missing, in which case the only solution is to use wired methods or buy a special adapter that connects through a USB Type-C connector, although this solution is not standard and may look unaesthetic.
Set up direct wireless charging
Unlike many other smartphone features, classic wireless charging (when the phone is charged from the station) on Xiaomi devices does not have a separate on button in the interface.The principle of operation is based on the physical interaction of the coils: once the phone is in the range of the electromagnetic field of the base, the system automatically activates the energy intake.
To start the process, you need to perform a series of simple steps: Make sure there are no foreign objects between the back of the smartphone and the surface of the charger, such as metal rings, access cards or cases that are too thick. The presence of metal can cause heating and blockage of the current by the security system.
⚠️ Warning: Using cases with metal plates or magnetic rings (MagSafe-compatible for other brands) can lead to critical rear panel overheating and battery damage.
Once you've placed the device on the platform, you're going to hear a characteristic beep, and you're going to see a charging animation on the screen. If that doesn't happen, check if the charger is connected to the network and the indicator is on the base itself. Sometimes the problem is the power supply that doesn't give you enough power to run the induction station.
💡
For maximum efficiency, remove thick protective covers (more than 3 mm thick) during wireless charging, as they increase the distance between the coils and reduce efficiency.
Activation of reverse wireless charging
The situation changes dramatically when you need to use your Xiaomi as a power source for other gadgets, such as headphones or smart watches.This mode, known as Reverse Wireless Charging, requires manual activation through the system menu, as its constant operation would quickly drain the main battery.
To enable this feature, follow the following steps: First, make sure your phone is above 20-30% charge, otherwise the system may block the power output to keep the smartphone running properly.
Find a section that might be called Battery or Advanced Settings, depending on the version of the MIUI or HyperOS shell. Inside this menu, look for Back Wireless Charging. Switch the slider to the active position. After that, the phone will start generating an electromagnetic field.
☑️ Algorithm for enabling reverse charging
Once the mode is activated, place the second device exactly in the center of the back of your phone. Accurate positioning is critical, because the power transmission zone is limited to a few centimeters. If the devices are not connected, try to slightly shift the gadget-receiver.
Management through engineering menu and hidden functions
For advanced users who want to check the status of the coils or diagnose problems, there is an access to the engineering menu, which allows you to see the technical parameters of the battery and the connection status in real time, which is not available in normal mode.
To enter the test menu, open the Phone app and enter a special code. Most Xiaomi devices use the combination ##6484##. Once you enter the code, the list of CIT tests will open.
##6484##The list that opens up is a wireless charging item, which can be called Wireless charging, Wireless reverse charging, or a hardware version number, and it will force the coil to be activated, allowing it to be tested without being connected to an external database.
⚠️ Warning: Be careful when changing the settings in the engineering menu. Do not change the settings, the value of which you do not know, as this may lead to incorrect operation of the power management system.
If the test shows the status of "Charging" when placed on the base, but the phone does not charge in normal mode, the problem is likely software, in which case, resetting settings or updating the firmware to the current version can help.
Optimizing and accelerating the charging process
The wireless charging speed on Xiaomi smartphones is highly dependent on operating conditions and equipment used. Standard power is often limited to 5-10 watts, unless proprietary stations from the manufacturer themselves are used that support fast charging protocols.
To achieve maximum speed, you need to observe the temperature regime. When the case is heated above a certain threshold, the system artificially reduces the charging current to prevent damage to components.
- 🌡️ Watch the temperature: if the phone is hot, the process will go slower.
- 🔌 Use the original power supply for the charging station that meets its power requirements.
- 📱 Turn off the screen or put your phone into Do Not Disturb mode while charging to reduce background power consumption.
It’s also worth noting that the phone’s vertical position at the station often provides a better heat sink than the horizontal one, and some users have noted that charging is faster if the phone is lying on a cool surface, such as a table made of stone or metal (through a protective pad).
Why can the charging stop?
Diagnostics and troubleshooting
If your Xiaomi wireless charging stopped working suddenly or doesn’t work at all, you need to conduct a system diagnostics, and most often the problem lies in banal things that are easy to overlook on the first inspection.
First, check the integrity of the charging cable and the power supply. Induction stations are sensitive to the quality of the incoming current. Try replacing the cable or connecting the base to another socket. Also, wipe the back cover of the phone and the surface of the charger from dust and dirt.
In rare cases, you may need to calibrate the battery or reset your network and connection settings. If nothing works and the phone is not responding to any charging base, the wireless charging module inside the device may have failed, and you may need to contact a service center to replace the component.
