How to put wireless charging on a Xiaomi phone

Many Xiaomi smartphone owners are wondering if it is possible to add wireless charging to their device, if it was not originally intended by the manufacturer. This desire is understandable, because Qi technology significantly improves the usability of the gadget, eliminating the need to constantly connect the cable. However, before you start any action, you need to clearly understand the technical side of the issue and the possible risks to your device.

This function can be implemented in two main ways: software (for rare exceptions) or hardware by installing a special receiver. In the vast majority of cases, it is a physical modification of the device. You will need to disassemble the smartphone, which automatically deprives you of an official warranty if it has not expired. So weigh the pros and cons before opening the case.

It is important to note right away that not all Xiaomi models have the necessary internal components to work with wireless power. Even if you install a receiver, the lack of an appropriate check board in the power chain can make the procedure useless. In this article, we will detail how to check your phone, what tools will be required and whether the game is worth the candle in your particular case.

Verification of compatibility and technical capability

The first step before any modification is to thoroughly diagnose your device, and don’t rely on rumors or forums that say “everything can be put on Xiaomi.” Technically, inductance coils and a power controller must be provided to run wireless charging inside the case. Entry-level budget Redmi and Poco models often lack these components at the hardware level.

You can check for hidden support through an engineering menu or special diagnostic applications, although they do not always give a 100% guarantee. A more reliable way is to search for disassembly of your particular model on specialized resources. If there is no contact platform on the motherboard for connecting the Qi module, you will not be able to implement the function in standard methods, in which case you will need a complex soldering of additional controllers, which is only possible for experienced engineers.

• 🔍 Check the specifications on the official website: the presence of the word "Wireless" or "Qi" in the characteristics.
• 📱 Use applications like this. AIDA64 or Device Info HW battery-view.
• ⚙️ Look for teardown of your model in forums 4PDA or XDA Developers.

⚠️ Note: If wireless charging is not mentioned anywhere in your smartphone specification, the probability of successful software activation is near zero. Any promises of “magic codes” to activate hidden features in this case are a fraud.

Also worth considering is the thickness of the case and the material of the back cover: Glass and ceramic backs allow an electromagnetic field to pass, whereas the metal back completely blocks the induction coil. If you have a model with a metal body, installing a wireless charging will require replacing the back cover with a glass one or using special linings, which significantly changes the ergonomics of the device.

Required tools and components for installation

If you're convinced of the technical feasibility of the installation, the next step is to prepare the workspace and purchase components. The main component you'll need is a thin wireless charging receiver (Qi receiver), which comes in two types: a USB Type-C (or Micro-USB) connector and a contact platform for direct connection to the board. For modern Xiaomi, the second option is preferable, since it allows you to keep waterproof and does not occupy the charging port.

To disassemble the smartphone, you will need a set of precision screwdrivers, since the screws in Xiaomi can have different lengths and types of hats. Also, an indispensable tool will be a suction cup for neatly removing the back cover and plastic blades (mediators) for snapping latches. Metal tools are best avoided so as not to damage the plumes or close the contacts on the board.

An important element is the adhesive base. Once the case is opened, the old adhesive loses its properties, and the phone will be left without protection from dust and moisture, buy a special adhesive B-7000 or T-7000, or a ready-made adhesive frame for your model, which will ensure that the case is tight after all work is completed.

When choosing a module, pay attention to its thickness. Too thick coil may not fit under the back cover, especially in compact models. The ideal option is a module with a thickness of no more than 0.8 mm. Also check the declared power: for fast operation, it should be at least 10 W, although most universal modules are limited to 5-7.5 W.

Process of installing the wireless charging module

The installation process itself requires the utmost care and care. Start by turning off your smartphone and retrieving it. SIM-Heat the perimeter of the back cover on a thermophen or special heating pad to a temperature of about 80-90 Do not overheat the device so as not to damage the battery or display.

Carefully suction the lid and run the mediator around the perimeter, releasing the latches. After removing the lid, first of all, unplug the battery plume from the motherboard, a critical safety step to avoid short circuits when working with internal components.

Find a place to place the coil. It's usually placed directly on the battery or on the metal screen that covers the board. If you use a module with contacts, they must be gently connected to the charging port contacts or contacts on the board (if soldered by the manufacturer). USB-Receiver, its tail is inserted into the charging port, but this is a less aesthetic and reliable option.

⚠️ Warning: When laying the coil, make sure that it does not clamping the display plumes or buttons. Mechanical pressure on the plumes can lead to stripes on the screen or volume buttons failure in the future.

Once you have the module and the contacts attached, put the device back together, apply a new layer of glue around the perimeter of the case, and press the back tightly, and you can use rubber harnesses or a load for 1-2 hours before the glue is completely dry.

Setting up the software and activating the function

After the module is physically installed, the software part often happens automatically. Current versions of MIUI and HyperOS are able to recognize third-party Qi receivers as a standard charger. However, additional adjustment may be required to fully work and display charging status.

Go to the battery settings and check if a new menu item related to wireless charging has appeared. In some cases, the system may not show charging animations, but the process will go. To monitor, use third-party apps that show the current and voltage entering the battery.

If the phone is charging very slowly, the problem may be calibration. Try completely discharging the device before it turns off, and then wirelessly charging up to 100% when it's off, which will help the power controller recalibrate the percentages and charge modes.

Xiaomi engineers sometimes add support for new charging protocols to new versions of MIUI. Make sure you have the latest available software for your model installed to rule out software bugs.

Use of reverse wireless charging

Many of Xiaomi’s flagship models support reverse charging, allowing you to use your smartphone as a powerbank for other devices. If your phone supports this feature hardwarely but it’s not active, it’s worth checking the settings. This feature is especially useful for charging TWS headphones, smartwatches or other smartphone in an emergency.

To turn on, go to Settings → Battery → Reverse wireless charging. Here you can activate the function and adjust the shutdown threshold so that the phone does not run to zero, powering other gadgets. Note that the speed of such charging is usually low (about 5-10 watts), so it is more suitable for maintaining charge than for fast charging.

💡

For maximum reversible charging efficiency, remove the covers from both devices.Thick or metal cases can interfere with power transfer and cause overheating.

When using reverse charging, the phone can get appreciably warmer. It's a normal physical process, but if the temperature gets too high, the system will automatically turn off the power supply to protect the components. Don't cover the devices during this process and ensure good ventilation.

Frequent discharge and charge cycles combined with heating reduce battery life faster than normal use.

Challenges, security and outcome recommendations

Installing wireless charging is a risk-free interference with the design of the device. The main problem that users face is overheating. A coil placed on top of the battery can heat itself and heat the battery, which negatively affects the chemistry of the lithium-ion cell.

Another common problem is unstable contact: if the module is glued poorly or the train is compressed, charging can appear and disappear at the slightest movement of the phone, which can damage the charging port or power controller due to constant voltage surges.

• 🔥 Keep an eye on the temperature of the body during the first charging cycles.
• 🔋 Do not leave your phone on wireless charging unattended overnight at first.
• 📉 Be prepared for the charging speed to be lower than through the cable.

⚠️ Warning: If you notice a bloating battery or a foreign smell of plastic when using the installed module, immediately stop using and disassemble the device.

As an alternative to a complex internal installation, consider off-the-shelf external solutions like Qi-enabled battery cases or receivers inserted into a USB port. They don't require disassembling the phone and can be easily removed at any time. While they add volume to the device, it's often a safer and more reliable way to go.

To sum up, installing wireless charging on Xiaomi is a real thing, but it requires technical skills and an understanding of the risks. For flagship models, it is often easier to buy an original wireless charger if the feature is already built in but hidden software, or to accept its absence in budget segments. A critical success factor is the presence of a coil contact group soldered on the board, without which installing an external module is impossible without complex soldering.

💡

The safest way to get wireless charging is to choose a Xiaomi model with already built-in Qi support when buying, rather than modifying the device after the fact.
