Xiaomi 12 is a flagship smartphone with wireless charging, but many users have difficulty connecting for the first time. Unlike wired charging, where you just plug a cable, it requires the right setup and compatible hardware. In this article, we will examine all the nuances from checking hardware support to optimizing charging speed.
Wireless charging on Xiaomi 12 works according to Qi standard, but not all chargers are equally efficient. For example, the original adapter from Xiaomi provides power up to 50W, whereas universal stations are often limited to 10-15W. We will tell you how to avoid typical errors and achieve maximum speed.
1. Verification of compatibility of Xiaomi 12 with wireless charging
Before you buy a charging station, make sure your Xiaomi 12 supports the technology.All the series modifications (Xiaomi 12, 12 Pro, 12X) are equipped with a wireless coil, but there are nuances:
- 🔋 Xiaomi 12 and 12X: support 50W (with an original adapter, and 10W (standard Qi-devices).
- 🔋 Xiaomi 12 Pro: maximum power 50W, It requires a Mi Wireless Charging Pad station.
- ⚠️ Models for some regions (e.g. global version 12 Lite) may have reduced functionality.
To check the support on your device:
- Open Settings → About the phone → Full specs.
- Find the Battery section – there should be a line Wireless charging: Yes.
- If no item is available, use the AIDA64 application (Battery section).
⚠️ Note: Some firmware (for example, customized) MIUI-ports may hide wireless charging information, in which case try to connect your phone to a charging station — if the charging indicator appears on the screen, the function works.
2. Which charger to choose for Xiaomi 12
Not only does speed depend on the choice of charging station, but also safety. Xiaomi's original accessories are optimized for flagships, but cost more.
| Type of device | Max. Power. | Pluses | Cons |
|---|---|---|---|
| Mi 50W Wireless Charger | 50W | Optimal speed, fan for cooling | Expensive, just for Xiaomi |
| Universal Qi stations (Anker, Belkin) | 10-15W | Cheaper, compatible with other devices | Slow charging, possible overheating |
| Car wireless holders | 7.5-10W | Comfortable in the car, compact | Low power, requires precise installation |
Critical: Xiaomi 12 does not support reverse wireless charging (for example, for charging headphones or watches), this feature is only available in the Mi 11 Ultra series and later.
Selection recommendations:
- 💡 For maximum speed: Mi 50W Wireless Charger (article) MDY-13-EM).
- 💡 Home / Office / Anker PowerWave Pad (15W, budgetary).
- 💡 For travel: Baseus folding stations with Qi support EPP.
💡
If you use a case that is more than 3 mm thick, remove it before charging – this will increase efficiency by 20-30%.
3. Step-by-step instruction: how to turn on wireless charging
Unlike wired charging, you don't have to activate the function in the settings, you just need to place the phone correctly on the station.
Make sure the charging station is plugged in | Check that the phone is free of metal accessories |Use the original power adapter (if required) |Place the phone in the center of the charging pad-->
Action:
- Connect the charging station to the power source. 50W-Charges use the power supply at least 65W (For example, Xiaomi GaN Charger).
- Put the Xiaomi 12 in the center of the court with a screen upwards. Some stations have a magnetic lock, which will help you to correctly orient the phone.
- Wait for the beep or vibration (if enabled in the settings) and the charge indicator will appear on the screen.
- To speed up the process, activate the Fast Charging mode in Settings → Battery.
If the phone does not start charging:
- ❌ Check if he's moved from the center of the court.
- ❌ Make sure there are no foreign objects (coins, keys) between the phone and the station).
- ❌ Restart your phone – sometimes helps with the charging controller malfunction.

4. Optimization of wireless charging speed
Even with the original station, Xiaomi 12 can charge slower than expected.
| Problem. | Reason. | Decision |
|---|---|---|
| 10W speed instead of 50W | Unoriginal station or power supply | Use the Mi 50W Wireless Charger + 65W+ block |
| The phone is heating up and slowing down. | Active processes or high ambient temperature | Close background applications, charge in the shade |
| Charging is interrupted | Unstable position of the phone | Use a magnetically fixed station |
Additional tips for acceleration:
- ⚡ Turn on the mode of the aircraft - this will reduce the load on the processor and reduce heating.
- ⚡ Disable Battery Optimization for System Applications in Settings → Battery → Optimization.
- ⚡ Use firmware. MIUI latest version – in old builds there may be bugs with a charging controller.
⚠️ Note: If the phone is charging at speed 5W despite using the original station, check the power cable. USB-C cables often do not support high currents.Recommended option: Xiaomi USB-C to USB-C (articular CDY-09-EM).
5. Common Mistakes and How to Avoid Them
Many users make the same mistakes that lead to slow charging or battery damage.-5 problem:
- Use of uncertified stations: Cheap chargers without Qi certification can produce unstable voltages, which reduce battery life. Check for the Qi logo on the package.
- Charging at extreme temperatures: The optimal range for wireless charging is 10-35°C. At temperatures above 40°C, the controller automatically reduces power to 5W.
- The wireless charging coil in Xiaomi 12 is located at the top of the case. If the phone is crooked, efficiency drops by 40-50%.
- Ignore firmware updates. MIUI 13.0.5 and later fixes charging station recognition bugs. Update the software via Settings → System Update.
- Charging through thick cases. Cases with metal inserts or thickness >3 mm block the magnetic field. Use thin silicone cases or remove them.
💡
The most common reason for slow charging is a mismatch of standards. Make sure your station supports Qi EPP (Extended Power Profile) for power above 10W.
6. Alternative methods of wireless charging
If you don’t have the original Xiaomi station but want to speed up charging, consider these options:
- 🔌 Magnetic-fixed adapters, such as MagSafe-compatible adapters (although Xiaomi 12 does not support MagSafe directly, some universal holders work via a lock ring).
- 🔌 Active cooling charging stations: Fan-operated models (e.g. RAVPower) 65W) They can maintain high power for longer.
- 🔌 Multifunctional docking stations: Devices like the Anker 633 Magnetic combine wireless charging of a phone and a watch, but the power for a smartphone is limited. 10W.
For homemade enthusiasts, you can modify the station by adding an extra radiator, but that voids the warranty and requires soldering skills, and we don't recommend such experiments without experience.
If you travel frequently, look for portable wireless power banks (like the Zendure SuperTank Pro) that support 15W and are compatible with the Xiaomi 12, but weigh more than usual.
7.Safety: How not to ruin the battery
Wireless charging is convenient, but if used incorrectly, it shortens battery life.
- 🛡️ Don't leave your phone charging overnight. After 100%, the controller turns off the power, but periodic recharging to maximum wears out the battery. Use Optimized Charging in Settings → Battery.
- 🛡️ Avoid charging at high temperatures. If the phone gets hot in the sun, let it cool before connecting to the station.°C damages lithium polymer elements.
- 🛡️ Use only certified accessories. Cheap chargers without voltage protection can take out the power controller.
To check the status of the battery:
- Install the AccuBattery app (available on Google Play).
- Check the discharge schedule – if the capacity has fallen below 80% of the original, it is time to replace the battery.
- Calibrate the battery: discharge the phone to 0%, then charge to 100% without interruptions.
⚠️ Note: If after wireless charging the phone is turned off when 20-30% If you have a battery, it's a sign of battery damage. 12 without special equipment is dangerous (the risk of fire).
