Why Xiaomi Redmi 5 has stopped charging and how to fix it
Your Xiaomi Redmi 5 suddenly stopped responding to the charger? Is the screen not turning on, the charging indicator not burning, and the battery is discharged to zero? This problem is familiar to many owners of budget Xiaomi smartphones, especially after 2-3 years of operation. The reasons can lie in both banal wear of accessories and serious hardware malfunctions, from oxidized contacts to the failure of the power controller.
In this article, we will look at all the possible reasons why Redmi 5 does not charge, from the simplest (damaged cable) to the most difficult (battery motherboard malfunction), how to diagnose the problem yourself, what manipulations can be done at home, and in what cases you should contact the service center, and we have collected topical tips on prevention and answers to frequent user questions.
If the phone is dead and doesn't show signs of life, start by checking the charger and the cable. If the Redmi 5 is turning on but charging is too slow or interrupted, the problem may be a software failure or battery wear. Next, you'll find step-by-step instructions for each case.
1. Checking of charger and cable
Start with the obvious: 90% of charging problems are due to a faulty charger or cable. Xiaomi Redmi 5 supports Quick Charge 2.0 technology, but even the original accessories fail over time.
- π Connect the charger to another phone or tablet, and if it works, it's not the problem.
- π± Try charging Redmi 5 with another cable (preferably original or certified). USB Type-C β It often breaks down at the base.
- π Connect your phone to your computer or power bank. If you're charging, it's the charger's fault.
- π Check the charging connector on your phone, whether there's any debris or dust or bent contacts inside, and you can hear a slight click when you connect the cable.
Pay special attention to the cable. Cheap non-original cords often have thin veins that break at the base of the connector. If you bending the cable, you lose charging, it's time to replace it. Also check if the charger warms up during operation: overheating indicates a short circuit or failure of the capacitors.
β οΈ Warning: Never use chargers with an output current greater than 2A or a voltage higher than 5V - this can damage the Redmi Power Controller 5. The original Xiaomi ROM is labeled 5V/2A.
2. Cleaning of the charging connector and contacts
If the charger and cable are working, but the Xiaomi Redmi 5 is still not charging, the problem may lie in a contaminated or oxidized connector. Over time, dust accumulates inside the USB-port, pile from pockets, and contacts can become covered with oxide - especially if the phone was in rain or operated in wet climates.
To clean the connector you will need:
- πͺ₯ Toothpick or plastic spatula (not metal!).
- π§΄ Alcohol (isopropyl or medical 90%+).
- π§» Cotton swabs.
- π‘ Lantern (for lighting the connector).
Step-by-step:
- Turn off the phone and remove it. SIM-memory-card.
- Hold the flashlight to the connector and inspect it for debris, carefully remove visible contamination with a toothpick.
- Soak the cotton swab in alcohol and wipe the contacts inside the connector. Don't press too hard!
- Let the phone dry for 10-15 minutes before connecting the charger.

If you haven't been charging after cleaning, try to slightly lift the jack tongue (central plastic partition) - sometimes it flexes and doesn't make close contact with the cable.
β οΈ Warning: Do not use metal objects (needles, knives) to clean the connector, they can close the contacts or scratch the coating. If corrosion (green plaque) is visible inside, the phone may have come into contact with moisture, in which case professional diagnosis is required.
3. Diagnostics of the battery and its wear
Xiaomi Redmi 5 is equipped with a removable battery capacity of 3300 mAh. Over time, lithium-ion batteries lose capacity: after 500-800 charging cycles, their wear can reach 30-50%. If the phone turns on only from the charger and immediately turns off when the cable is disconnected, the battery is likely to fail.
Check the status of the battery can be using the engineering menu or third-party applications:
- π AccuBattery (shows wear, temperature, charging speed).
- π§ CPU-Z (Battery section β battery health data).
- π± Enter ##4636## in the dialer and select Battery Information.
Normal performance for Redmi 5:
| Parameter | Norma. | Critical significance |
|---|---|---|
| Level of wear and tear | 20% | more than 50% |
| Capacity | 2800β3300 mAh | less than 2,000 mAh |
| Temperature. | 20β40Β°C | 50Β°C |
| Tension. | 3.7β4.2V | less than 3.4V |
If the battery is swollen (the phone body is deformed), it must be replaced immediately - it is dangerous to health! A bloated battery can damage the screen or motherboard. To replace the original battery MB38 or analogues from proven manufacturers (for example, Remax, Baseus).

4. Software failures and resetting of settings
Sometimes the Xiaomi Redmi 5 doesnβt charge due to software bugs, such as firmware failure, application conflict, or system files corruption. If the phone turns on but the charging is jerky or not going at all, try the following steps:
- π Reboot. Hold the power button for 10 to 15 seconds until the phone turns off and turns on again.
- ποΈ Cache clean. Go to Settings β Memory β Clear cache.
- π οΈ Safe Mode. Press the power button, then hold your finger on the Turn off option, you'll be prompted to go to Safe Mode, and if it's charging normally, it's the third-party app's fault.
- βοΈ Settings Reset. Settings β Additional β Reset and Reset β Settings Reset. Attention: This will delete all data!
If the phone doesnβt turn on but reacts to charging (the indicator lights up), try a forced reset:
- Connect the charger.
- Press the button Power + Volume up for 10-15 seconds.
- Let go when the Mi logo appears.
If the charge didn't start after the reset, the problem could be a damaged bootloader or firmware, in which case flashing through Fastboot or Recovery will help. Instructions for Redmi 5 (codenamed rosy) can be found on the 4PDA or XDA Developers forum.

Before resetting, remove the SIM- card and memory card, which will speed up the process and reduce the risk of data loss.
5. Problems with the power controller and motherboard
If all previous methods did not help, the reason may lie in a hardware malfunction:
- π₯ The charging controller (the BQ24192 chip or similar) has burned.
- π The motherboard tracks were broken (often after a fall).
- β‘ Short circuit in the food chain.
- π The USB connector is defective (contacts are soldered).
It is difficult to diagnose such problems at home, but there are indirect signs:
- The phone does not respond to any charger, even the original one.
- When connecting the cable, the phone overheats in the connector area.
- Charging is only in a certain position of the cable.
- The phone turns on, but immediately turns off with a Battery low error.
The repairs will require:
- Disassemble the phone and check the board for blackened elements (burnt resistors, capacitors).
- Call the power supply chain with a multimeter (checking the resistance between the contacts of the battery and the controller).
- If necessary, replace the controller or re-sweeten the USB connector.
Cost of repair in the service center:
| Type of malfunction | Cost (rupe) | Duration of repairs |
|---|---|---|
| Replacement of the charging connector | 800β1500 | 1-2 hours |
| Repair/replacement of the power controller | 1500β3000 | 1-3 days |
| Recovery of the tracks on the board | 2000β5000 | 2-5 days |
β οΈ Warning: If you don't have experience in soldering SMD- components, don't try to repair the board yourself! improper actions can cause the phone to fail completely.
6. Alternative charging methods
If the standard charging doesnβt work, but the phone is still alive, you can try alternative methods:
- π Wireless charging. Redmi 5 doesn't support Qi out of the box, but you can use an adapter with a USB- connector (like the Nillkin Magic Disk) glue it to the back cover and plug it into the charging connector.
- π§ Charge via OTG If the USB connector is damaged but the phone is switching on, you can plug in the OTG- cable and power through it (a special adapter is required).
- π External battery: Connect the Redmi 5 battery to a universal charger (e.g., iBattz Mojo Refuel).
- π» Charging from a PC. Sometimes the phone only takes the charge from the USB- port of the computer (due to the current limit).
For wireless charging, you will need:
- Buy an adapter with a Micro-USB connector (for example, Xiaomi Wireless Charging Receiver).
- Connect it to the phone and fix it on the back cover.
- Place your phone on a wireless charging station (which supports Qi).
Note that alternative charging methods are slower than standard ones and may not work if the power controller is a problem, and avoid cheap wireless adapters, which often overheat.
π‘
Wireless charging is a temporary solution, and if the USB connector is damaged, it still needs to be repaired or replaced.
