How to add wireless charging to Xiaomi phone: module selection and step-by-step installation

Wireless charging has become the standard for flagship smartphones, but many Xiaomi models — especially from the budget lines of Redmi and the likes of the new model. POCO — And we're still missing this feature, and fortunately, you can add it yourself without having to buy a new device, and in this article, we're going to go through all the steps, from choosing a compatible module to testing the finished system.

It is important to understand that modification of the phone always carries risks, from loss of warranty to damage to internal components. 90% We will focus on solutions for popular models: Xiaomi 11T/12T, Redmi Note 10/11 Pro, POCO F3/F4 Others where the integration of the Qi module is technically possible.

Before you start, check if your model supports fast wired charging (from the 18W). This indirectly indicates compatibility with wireless solutions, and also note that after installation, the thickness of the phone will increase by 1.5-2.5 mm - you will have to change the case or use the device without it.

Compatibility: What Xiaomi models can be modified

Not all Xiaomi smartphones are suitable for wireless charging.

• 🔋 The thickness of the case is at least 8.5 mm (thinner - there is not enough space for the module).
• 🔌 Type of charger connector - only USB-C (MicroUSB is not supported).
• 🔄 Removable back cover (or the possibility of its neat dismantling without damage).
• ⚡ Support for fast charging (from) 18W) — Simplifies the integration of the module.

Below is a table with proven models and their features:

Critical information: models with metal back panels (such as Xiaomi Mi 6 or Mi 8) are not compatible with wireless charging due to the shielding of the signal, in which case you will need to replace the cover with plastic or glass, which greatly complicates the process.

⚠️ Note: If your phone has a built-in battery with a thermal sensor (for example, Xiaomi 12 Pro), after installing the module, overheat protection may work.

2. Choosing a wireless charging module: what to look for

The market offers dozens of module options, but not all are suitable for Xiaomi.

• 🔌 Type of connection – must correspond to the phone connector (USB-C flat-block).
• ⚡ Power - optimal 10–15W (module 5W They will charge too slowly).
• 📏 The thickness is no more than 1.5 mm for most Xiaomi models.
• 🧲 Magnets – simplifies positioning at the charging station.
• 🔧 Set – ideally should go with bilateral scotch 3M heatpaste.

Popular proven module models:

• 🛒 Nillkin Magic Disk is a universal module 10W Magnets are suitable for most Xiaomi.
• 🛒 Baseus Wireless Charging Module (1.2 mm) with support 15W, soldering.
• 🛒 Mi Wireless Charging Board – the original module from Xiaomi (suitable for Mi) 9/10 afterwork).

Before buying, check reviews on AliExpress or Amazon — look for references to your phone model. POCO F3 Often recommended module YCCTEAM flexible plume that does not require soldering.

⚠️ Attention: Modules overpowered 15W Xiaomi's battery can overheat if it's not designed for high currents. This is true for low-end models with 4,000-5,000 mAh batteries.

3. Necessary tools and telephone preparation

To install the module, you will need:

Set of screwdrivers (cross, flat, Torx) T3/T4)

Plastic mediators for disassembling the body

Dryer or thermo-air station (for removable cover)

A soldering iron with a thin sting (if soldering is required)

Multimeter for checking contacts

Double-sided scotch 3M heat-glue

Tap and shrink tube-->

Before the phone is disassembled:

1. Turn off the device and remove it. SIM-map + memory-card.
2. Discharge the battery to 20-30% – this will reduce the risk of fire in case of accidental circuit.
3. Back up your data via Mi Cloud or Google Drive.
4. Prepare the workplace: clean surface, good lighting, antistatic mat (if possible).

💡

If you don't have experience disassembling phones, practice on a non-working device or watch disassembly videos specifically for your model on YouTube. For example, Xiaomi Repair channel publishes detailed guides.

For models with adhesive back cover (Redmi Note 10 Pro, Xiaomi 11 Lite) will require a dryer warm-up. Temperature should be 60-80°C is not higher so as not to damage the display. Use mediators to gently tuck the lid, starting at the corners.

4. Step-by-step installation of the wireless charging module

The installation process is divided into two scenarios: soldered and soldered (for modules with a plume).

Scenario 1: Trailed module (without soldering)

Suitable for most modern Xiaomi:

1. Remove the back cover of the phone as described in the previous section.
2. Disconnect the battery plume from the motherboard (use a plastic mediator).
3. Place the wireless charging module on the back of the battery, align it in the center. Secure it with double-sided tape.
4. Connect the module plume to USB-C port of the phone (usually included in the adapter).
5. Collect the phone in reverse order, making sure that the plume is not clamped.

Scenario 2: The soldering module

It requires soldering iron skills.

1. After removing the cover, find contacts VCC (food GND (land) on the motherboard (usually near the charging socket).
2. Seal module wires to these contacts using a heat shrink tube for insulation.
3. Fix the module on the battery with heat glue or tape.
4. Check with a multimeter the absence of a short circuit before assembly.

For models with NFC (for example, Xiaomi 11T Pro) make sure that the module does not overlap the antenna, otherwise contactless payments will not work. NFC-chip.

5.Configuring and testing wireless charging

After the phone is assembled:

1. Turn on the device and check if charging is determined. The screen should display a notification "Wireless charging is connected."
2. Install the Ampere app from Google Play to measure the real charging power. 10W-modules normal indicator - 6–8W (Some of the energy is lost as heat).
3. Check the case heating after 15 to 20 minutes of charging. Temperature above 45°C is considered critical.

If the charging is not working:

• 🔌 Check the connection of the plume / wires.
• 🔋 Make sure the charging station supports the Qi standard.
• 📱 Restart your phone – sometimes you need to initialize new hardware.
• 🔧 For soldered modules, check the quality of contacts with a multimeter.

💡

If the charging power is lower 3W, The problem is probably the incompatibility of the charging station and the module).

To accelerate charging, you can turn off battery optimization in the settings: Settings → Battery → Power regimen → High productivity.

Frequent problems and their solutions

Even with the right installation, there can be problems.

Overheating is the most common problem, if the body temperature is above 50.°C,:

• 🛑 Stop charging and let the phone cool down.
