Your Xiaomi has stopped charging, and you don't know what the reason is? The problem can be both a simple cable damage and a serious battery or motherboard malfunction. In this article, we'll look at all possible causes, from software failures to hardware breakdowns, and give step-by-step diagnostic and repair instructions.
Don't rush to bring your phone to the service center: 70% of the time, you can solve the problem yourself in 10 to 30 minutes. We tested the solutions on the Redmi Note 12 Pro+, POCO X5 Pro, Mi 11 Ultra and other popular smartphones of the brand. If after checking all the charging points and did not go β at the end of the article you will find a list of official service centers Xiaomi with addresses and prices for repairs.
1. Checking of charger and cable
Start with the simplest one: 9 out of 10 charging problems are related to a cable, adapter or socket. Even if the cable looks whole, the veins inside could have damaged β especially if you often bend it at the base or store it in a strained state.
Here's how to check the components:
- π Connect another cable and power supply. Use an original or certified adapter (e.g. Xiaomi) 33W If the phone starts charging, the problem is with the old memory.
- π Look at the cable on the curves. Most often, the sections at the connector are rubbed. USB-C Pull the cable in different places, and if the charging stops, it needs to be replaced.
- π Check the socket or USB-Connect the charging to another power source (computer, power bank, other socket) If in some cases charging is a problem in the socket or the power outlet. USB-port.
- β‘ Use a voltage tester (multimeter). Connect the probes to the cable contacts: the output should be 5VΒ±0.25V (for standard charging) or 9V/12V (Deviations indicate a malfunction of the adapter.
Importantly, cheap uncertified cables and adapters can not only slowly charge the phone, but also damage the power controller on the motherboard. If Xiaomi stopped charging after using the left-handed RAM, the U2 IC (Power Management Microchip) most likely burned down.
2.Cleaning the phone's charging port
The USB-C charging port is one of the most vulnerable spots in Xiaomi: Dust, pocket pile, moisture and contact oxidation can completely block charging, and the phone can detect the cable connection (the battery icon appears), but the current does not arrive.
How to clean the port:
βοΈ Cleaning the port USB-C
- πͺ₯ Turn off the phone and get it out. SIM-card (if the port is combined with a tray).
- π¦ Light a flashlight to the port: if you see debris, pile or oxidation (green / white plaque) β it must be removed.
- πͺ΅ Use a wooden toothpick (not metal!) gently tuck in the dirt without pressing on the contacts.
- π¨ Blow the port with compressed air (a tank for cleaning equipment). Don't blow with your mouth - saliva can oxidize the contacts.
β οΈ Please note: Never use it to clean the port. USB-C It can bend or close the contacts, which will short-circuit and the power controller will fail, and if the phone doesn't charge after cleaning, it may have oxidized the contacts on the board (a soldering station is required).
What to do if water gets into the port?
Diagnostics of the battery
Xiaomi's average battery life is 2-3 years (or 500-800 charge cycles). If the phone suddenly stopped charging, it could be that the battery swelled, went down, or the charge controller failed.
- π The phone is switched on only from charging, but immediately switches off when the cable is turned off.
- π Charge drops from 50% to 1% in minutes.
- π₯ The body of the phone is swelling (especially noticeable on glass models Mi 11 or Redmi). K50).
- β‘ The screen displays a warning: βBattery damagedβ or βUse the original RAM".
How to check the status of the battery:
- Enter the engineering code for the diagnosis: ##4636## Go to the Battery Information and check the parameters: - Charge level (should match the indicator on the screen). - Condition (if "Good" - battery is normal). - Temperature (normal: 25-40 Β°C; above 45 Β°C - overheating).
- Use the AccuBattery app (available on Google Play) to show the actual battery capacity and the number of charging cycles.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The phone does not turn on, but vibrates when charging. | Deep battery discharge (below 2.8V) | Use a booster to start or replace the battery |
| Charging is only in the off state | Failed charge controller on the board | Diagnostics in the service, replacement of the chip |
| Battery discharges quickly (from 100% to 0% in 1-2 hours) | Battery wear (capacity < 60% of nominal value) | Battery replacement (cost: 1,500β3,000) β½) |
| The phone gets heated and switched off when charging | Short circuit in the battery or on the board | Immediate shutdown! Diagnosis required! |
β οΈ Warning: If the battery is swelling, don't try to charge it. It could cause a fire or explosion! Immediately take the phone to a battery replacement service center. The cost of a replacement in official Xiaomi services is between 1,200 and 4,000. β½ (model-wise).
4. Software failures and settings
Sometimes the phone doesn't charge because of a firmware failure, incorrect settings, or application conflict.
- π Reboot your phone. Hold the power button for 10-15 seconds until the Mi logo appears. After rebooting, try plugging in the charging.
- π± Run the phone in safe mode. To do this, hold the power button, then press and hold "Switch off" β "Safe Mode. If you're charging in this mode, there's a problem in one of the apps installed.
- βοΈ Reset your charging settings. Go to Settings. β Battery β Battery settings β Resetting the adapter settings.
- π§ Update the firmware. Outdated software may conflict with chargers. Check the updates in Settings β The phone. β Updating the system.
If the phone only charges when it's off, but it doesn't charge when the screen is on, it's probably a problem with the power controller (PMIC), and that's where repairs to the service will help.

If Xiaomi is not charging from wireless charging, try resetting NFC settings: go to Settings β Connection & Sharing β NFC and turn off/on the module.
5. Checking the charging controller and motherboard
If all the previous steps didn't work, the problem is the hardware: the charging controller is faulty, the fuse is burned, or the motherboard is damaged, and these are the most complex breakdowns, and without soldering experience, they can't be fixed.
Signs of a faulty fee:
- π The phone does not respond to the cable connection (no vibration, no indicator lights).
- π₯ The charger is very hot or emits the smell of burning.
- β‘ The error appears on the screen: "Charging suspended. Temperature too high," even though the phone is cold.
- π± The phone is powered on, but not charged from any cable/adapter.
What you can do on your own:
- Check the charge fuse (if you have experience disassembling) on the board, it is marked as F1 or FUSE. If the fuse is burned (blackened or ruptured), it should be replaced.
- Check the charging controller chip (U2 IC, PMIC or BQ25896), and if it is blackened or swelled, a replacement is required.
- Check the power circuit with a multimeter. The battery contacts should have a voltage of 3.7-4.2V. If 0V is a problem in the board.
β οΈ Warning: If you don't have experience with a soldering station, don't try to repair the board yourself. Wrong soldering can completely disable the phone. The average cost of repairing a charging controller in the service is 2,500 to 5,000. β½.
