Modern wireless chargers from Xiaomi are famous for their reliability and stylish design, but even high-quality electronics are not immune to breakdowns. Owners often face the need for internal intervention when the device stops responding to the connection or begins to work incorrectly.
Disassembling these gadgets requires care, as manufacturers often use hidden screws and adhesives to ensure the monolithic body. In this article, we will take a detailed look at the process of dismantling popular models so that you can independently diagnose or replace failed components.
Before you start physically affecting your device, you need to understand that opening the case will automatically void the warranty. If your equipment is still in warranty service, it is wise to contact an authorized service center rather than risk it.
Tools and workplace preparation required
To successfully complete the dismantling, you will need specialized but affordable tools.Do not use kitchen knives or rough screwdrivers, as they can damage the plastic elements of the case or scratch the inner board.
The main tool will be a set of precision screwdrivers, including cross bits size PH000 and PH00, which is the size of the screws most often used in compact electronics Xiaomi to save space inside the case.
You will also need plastic spatulas (spoogers) or a mediator to gently snap the latches, and metal tools are best used with extreme caution to avoid damaging the circuit board tracks.
- 🔧 A set of precision screwdrivers with magnetic tips.
- 🧤 Plastic blades and suction cup for lifting the cover.
- 💡 Bright lamp or table light for a good overview of small details.
- 🧲 Magnetic mat or screw sorting container.
⚠️ Warning: Before starting work, be sure to disconnect the charger from the mains and let it cool completely if it has been used recently.Residual current in the capacitors may be minimal, but precautions will not be unnecessary.
Organize the workspace so that small parts do not roll under the furniture. It is recommended to use a bright surface on which small cogs and plumes are clearly visible.
Design features of Xiaomi models
Xiaomi engineers have applied different circuitry solutions to their products, but the overall architecture of wireless charging remains similar. Inside the case, there is usually a main board with a charge controller, an inductor coil and a power connector.
Most models, such as the Mi Wireless Charging Pad or the more powerful versions of the Mi Air Charge, have a body consisting of two main parts: an upper decorative panel with anti-slip coating and a lower base.
Importantly, some models may have hidden screws under rubber legs or decorative stickers, and a close visual inspection from all sides will help identify entry points.
| Model of the device | Type of attachment | Location of screws | Difficulty disassembling |
|---|---|---|---|
| Mi Wireless Charging Pad (10W) | Latches + screws | Under the rubber legs | Low. |
| Mi Air Charge (30W) | Glue + screws | In the hull's recess | Medium |
| Mi Vertical Charging Stand | Latchers | On the back panel. | Low. |
| Mi Turbo Charge (50W) | Combined | Hidden under the decor | Tall. |
Understanding the design of a particular model will avoid the use of excessive force, which can lead to the breakdown of plastic guides.
Step-by-step process of dismantling the hull
Start by looking for the fixing elements, flip the device over and look carefully at the bottom panel, and if you find rubber legs, gently tuck their edges with a thin blade or needle.
Under the rubber, there are often screws that hold the halves of the body together. Unscrew them and fold them into a prepared container. After removing all the visible screws, move on to the latching.
Insert a plastic blade at the junction between the top and bottom of the body. Move the tool along the perimeter, slightly pressing and turning to unplug the latches. A characteristic click will signal a successful opening.
☑️ The body opening algorithm
Don't try to open the device with one jerk. Act sequentially, releasing the latches in a circle to avoid them breaking. If the case does not respond, check if there is another hidden screw.
⚠️ Attention: When you separate the halves of the body, act slowly. Inside, you can connect an LED display or a temperature sensor connected by a thin plume that is easy to break when you move sharply.
Diagnostics of internal components and search for faults
Once you have a successful autopsy, you'll see the internal device, and first, visually inspect the circuit board for obvious defects, such as swollen capacitors, blackened from overheating or disconnected contacts.
The main element here is the charge controller, which controls the energy transfer process, and if you see traces of moisture on the board, you need to thoroughly dry the device and clean the contacts with alcohol.
A common cause of failure is a wire pulling away at the entrance to the body or a broken plume. Check the integrity of the connections with a multimeter in vertebrae mode.
- 🔍 Check the inductor coil for mechanical damage.
- ⚡ Call the entrance connector. USB contact with the payment.
- 🌡️ Inspect the heat paste on radiators and replace it if necessary.
If the visual examination does not reveal any problems, the controller itself or one of the transistors in the power supply chain may be defective, and further diagnostics will require an oscilloscope and electronics skills.
What to do if the safety lock is burned?
Typical problems and methods of their elimination
One of the common problems is that there is a weak contact in the power connector, and over time, the connector loosens, and charging stops turning on at the slightest shift in the cable.
This requires a neat soldering, you have to cut out the old socket and install a new one that's the same size and stitching, and you need a soldering iron with a thin sting and a flux.
Another common issue is overheating of the device, which may be due to a dried-up heatpaste between the coil and the housing or the board, and replacing the thermointerface often solves the problem and prolongs the life of the device.
If the charging is working but the phone can't see, the problem may be that the coil is shifting, make sure it's tightly attached to the body and locked, and sometimes the lining of the extra layer of thermal insulation helps.
⚠️ Warning: When soldering elements do not overheat the board. Prolonged exposure to high temperature can peel off tracks or damage adjacent components, making repair impossible.
💡
Use isopropyl alcohol to clean the board of dust and oxides. It evaporates quickly and leaves no conductive traces, unlike ordinary water or alcohol solutions with additives.
Assembly of the device and check of performance
After repairs or replacements, the device must be assembled in reverse order, and make sure that all plumes and wires are packed into their channels and not clamped by the case.
Connect the halves of the body, slightly pressing the perimeter to the characteristic snaps of the latches. Then install and twist all the screws, observing a moderate force so as not to break the thread in the plastic.
Stick the rubber legs back if they've been removed. If the legs have lost their stickiness, you can use a little double-sided tape to fix them.
Now connect the charger to the network and check it. The indicator should light up, and when you bring a compatible smartphone, the charging process should begin.
💡
A good assembly ensures not only aesthetic appearance, but also safety of operation. Poorly closed housing can cause dust and short circuit.
If the device didn't turn on the first time, don't panic. Check the connection of all internal connectors and the integrity of the inlet port soldering once again.
