You plugged Xiaomi into charging, but the indicator doesn't burn, and the battery percentage doesn't rise? Or the phone doesn't respond to the cable at all? The charging problem is one of the most common malfunctions of the brand's smartphones, but in 80% of cases it can be fixed on its own. In this article, we'll look at all the possible reasons why Xiaomi stopped charging, from the banal contamination of the connector to the hidden failures of the power controller.
It's important to understand that if the smartphone is completely discharged and does not show signs of life, diagnosis becomes more difficult. In such cases, first try alternative charging methods (about them below), and then go to deep testing. We have collected current data for 2026, including typical problems of new models (Xiaomi 14, Redmi Note 13, POCO F6) and old ones (Redmi 9, Mi 11).
1. Problems with the cable or charger
Start with the simplest: check the charger and the cable. According to service centers, 35 percent of the time, it's a damaged USB-C cable, especially if you're using cheap, non-original accessories.
- 🔌 Physical damage: rubbed insulation, bent connectors, traces of melting.
- 🔋 Power supply: if you use charging from another device, it may not provide enough current (for example, Xiaomi 13 Pro requires a minimum of 30 watts for fast charging).
- 🔄 Contact oxidation: green plaque on a cable plug or in a phone connector.
How do you check? Connect another charger (preferably the original one) and a cable. If the phone starts charging, the problem is solved. If not, move on to the next step. Don't use damaged cables: this can short-circuit and fail the smartphone power controller.
⚠️ Cables: Cheap Cables without Certification USB-IF Quick Charge protocols (TurboCharge) are often not supported, and not only does this slow down charging, it can damage the battery.
2.Contamination or damage to the USB-C connector
The USB-Type C connector in Xiaomi is one of the most vulnerable places, and dust, pile from pockets, moisture, or mechanical damage can block contacts.
- 📵 The phone is charged only in a certain position of the cable.
- ⚡ The charge is interrupted at the slightest movement.
- 🔌 The screen displays a notification saying, "Charging suspended. Humidity in connector".
How to clean the connector:
- Turn off the phone and remove it. SIM-card (if the model supports a removable tray).
- Light the connector with a flashlight and look for debris. Don't use metal objects, they can damage the contacts.
- Carefully remove the dust with a wooden toothpick or plastic spatula. For persistent contaminants, use alcohol wipes (at least 70% alcohol).
- Allow the connector to dry for 10-15 minutes before charging.
☑️ Cleaning the connector USB-C
If the problem persists after cleaning, the connector may be mechanically damaged (e.g., bent "tongues" of the connector), in which case the connector at the service center will need to be replaced. ₽, for flagships (Xiaomi 14 Ultra) – up to 3,500 ₽.
3. Software failures
Sometimes Xiaomi doesn't charge due to software errors, especially after updating MIUI or installing custom firmware.
- 🔄 Phone shows charging, but battery percentage doesn't change.
- 📱 The charging icon is displayed on the screen, but the device turns off after a few minutes.
- ⚠️ Error "Unsupported Accessory" appears when connecting the original cable.
Decisions:
- Safe Mode Restart: 1. Press the power button before the turn off menu appears. 2. Press and hold "Stop" → prompts you to go to Safe Mode. 3. Confirm and wait for the download. 4. Connect charging and check work. If Safe Mode is charging, there is a problem in a third-party application. Uninstall recently installed programs.
- Reset Charging Settings: Go to Settings → Battery → Battery Settings → Reset Adapter (not available on all models).
- MIUI Update: Check for updates in Settings → About Phone → System Update. Sometimes bugs are fixed in new firmware versions.
⚠️ Warning: If the phone is low to 0% and not turning on, do not try to flash it through the Fastboot without recharging.This can lead to a "brick" (completely inoperable) device.

4. Battery malfunction
The average battery life in Xiaomi is 2-3 years (or 500-800 charge cycles), after which the capacity drops, and problems may arise:
- 🔋 The phone only charges up to 80-90% and shuts down immediately.
- ⚡ The swelling is then interrupted, and then it is interrupted.
- 📉 The battery is discharged in a few hours, even in standby mode.
How to check the status of the battery:
- Type in the Phone app code ##4636## → select Battery Information. See Health. If it's below 70%, change the battery.
- Use the AccuBattery app (available on Google Play) to show real capacity and wear.
If the battery is swelling (the phone's body is deformed), immediately stop using the device. The billowing batteries can ignite.
| Xiaomi model | Cost of battery cost (₽) | Cost of work (₽) |
|---|---|---|
| Redmi Note 12 | 800–1 200 | 500–800 |
| Xiaomi 13 | 1 500–2 000 | 800–1 200 |
| POCO X5 | 900–1 300 | 500–700 |

💡
If you decide to replace the battery yourself, buy only original Xiaomi-branded batteries or certified counterparts (e.g., from ZMI). Cheap fakes can not only quickly fail, but also damage the power controller.
5. Damage to the power controller or motherboard
If all previous steps did not help, the problem may lie in the hardware:
- 🔧 Charging controller (often fails when using uncertified chargers).
- 🔌 microcircuit USB (Responsible for Recognition of Connected Devices).
- ⚡ Power chains on the motherboard (burn out during voltage surges).
Symptoms:
- The phone is not charged from any cable/charging.
- When connected to a PC, it is not defined as a drive.
- The error appears on the screen: "This charger is not supported."
Diagnosis and repair:
