12 Reasons Why Xiaomi Redmi Note 8 Pro Is Not Charging – and How to Fix It

Xiaomi Redmi Note 8 Pro

In this article, we will look at all possible scenarios why the Redmi Note 8 Pro refuses to charge: from simple (which you can eliminate yourself in 5 minutes) to complex (requiring intervention from the service center), you will learn how to diagnose a problem without special tools, what tests to conduct at home, and when you should not take risks and contact professionals.

We will pay special attention to the unique "diseases" of this model - for example, why after the update, the authors of the study will be able to explain the problem. MIUI The phone may not recognize the original charger, or why using cables from other brands (such as Samsung) can lead to a charging lock due to incompatibility of fast charging protocols. Is it true that the Redmi Note 8 Pro “does not like” wireless charging, and why sometimes the phone only charges when it’s off.

If you've tried to reboot your smartphone and clean the connector, but nothing has worked, don't rush to buy a new battery. In 60% of cases, the problem lies in the little things that users don't even know about.

1. Checking the charger and cable: why the original kit can bring

The first thing to do is make sure that the problem is not with the charger or cable. Even the original Xiaomi accessories fail over time, and the non-original ones may not support the Quick Charge 3.0 fast charging protocol used in the Redmi Note 8 Pro at all.

How to check:

1. Connect your phone to another charger (preferably an original Xiaomi charger or a proven brand like Anker).
2. Try another cable – best of all, a USB Type C certified for fast charging.
3. Connect the charger to another device (such as another smartphone or power bank) to make sure it works.

Please note the charging indication:

• 🔌 Charging is normal – the battery icon flashes or an animation of filling is displayed.
• ⚡ Quick charging is active – the lock screen appears the inscription Quick Charge or Turbo Charging.
• ❌ No charge, no reaction, or an unidentified charger warning appears.
• ⚠️ Charging is interrupted – the phone then takes charging, then not (often accompanied by an audible signal of connection / disconnection).

If you have another charger or cable that starts charging, that's solved. But what if the original set doesn't work? It might be the power controller in the charger itself. To check that, plug the charger into the charger. USB-Tester (e.g. Xiaomi) USB Tester or Baseus Power Monitor: If the output voltage is less than 5V or the current drops below 1A, the charger is malfunctioning.

Type-C connector pollution: how to clean the port without damage

One of the most common reasons why the Redmi Note 8 Pro doesn’t charge is dust, dirt, or oxidation of contacts in the Type-C connector. Over time, fibers from clothing, dust particles, and sometimes even metal shavings get inside the port (if you carry a phone in your pocket with your keys).

How to clean the connector safely:

• 🧲 Magnetic tip: use a special plastic blade to clean the ports (sold in phone repair kits). Do not use metal objects - they can damage the contacts!
• 💨 Compressed air: A spray of compressed air (such as cleaning keyboards) will help blow dust out of the depth of the connector. Keep the balloon vertical to avoid liquid.
• 🧴 Alcohol and Cotton Swab: Moisten the wand in isopropyl alcohol (90%+) And you can wipe your contacts carefully. Don't use vodka or cologne, they leave the film behind!
• 🔦 Lantern and magnifier: before cleaning, light the port - if foreign objects are visible inside (for example, a piece of a plug), it is better to contact the service.

⚠️ Warning: If you're cleaning the phone and it's not charging, and if you're connecting the cable, the connector is moving or it's a sign of mechanical damage, then cleaning won't help, you need to repair or replace the connector.

Also check if the tongue is bent inside the connector (which is responsible for fixing the cable) if the tongue is broken, the cable will fall out or contact poorly, and this can only be fixed in the service.

3. Software glitches: why the phone doesn't charge after the upgrade MIUI

Sometimes Redmi Note 8 Pro stops charging after firmware update MIUI This is due to a power controller malfunction or conflict in system services, especially when you update to the system. MIUI 12.5 and later, where the logic of charging control has changed.

How to diagnose a software failure:

• 🔄 Reboot: Sometimes a normal reboot helps. Press the power button for 10 seconds until the phone turns off, then turn it on again.
• 📱 Safe Mode: If the phone is charging in Safe Mode, the problem is in one of the apps installed. → long tap on "Switch off" → "Safe regime".
• ⚙️ Resetting: If the crash occurred after the update, try resetting to factory settings (Settings) → The phone. → Reset settings. Don't forget to make a backup!
• 🔌 Phone-off test: If the Redmi Note 8 Pro only charges when it’s off, it’s a sign of firmware or power controller issues.

If the phone started charging after the reset, but the problem came back after a while, it might be one of the apps to blame.

1. Remove recently installed programs.
2. Check battery consumption in Settings → Battery – if an application consumes too much power, it can block charging.
3. Turn off battery optimization for system applications (Settings) → Battery → Optimizing the battery).

⚠️ Warning: If the phone is no longer on after reset, don’t try to flash it yourself through the Fastboot. The Redmi Note 8 Pro uses Anti-Rollback protection, and the wrong firmware can turn the device into a brick".

4.Battery problems: how to know if the battery is out of order

Average battery life in the Redmi Note 8 Pro — 2-3 year 300-500 After that, the battery capacity drops, and the phone can do it:

• 🔋 Do not charge at all (if the controller blocks the faulty battery).
• ⚡ Charge only until 80-90% and shut down.
• 📉 Discharge in a few hours even when off.
• 🔥 Overheating during charging (it is dangerous!).

How to check the status of the battery:

1. Enter the number #4636## → Select "Battery Information." If Unknown status or charge level is unchanged, the battery is defective.
2. Use the AccuBattery app (available on Google Play), which will show the actual battery capacity, and if it's less than 3,000 mAh (at the initial 4,500 mAh), you need to change the battery.
3. Look at the physical state of the battery: if the phone body is swollen and the screen is moving away from the case, it's a sign of battery bloating. Turn off the phone immediately and don't use it!

If the battery is swelling, it cannot be pierced or compressed, this can cause fire.

The cost of a new battery for the Redmi Note 8 Pro in 2026 is from 1500 to 3000 rubles (depending on quality). Xiaomi original batteries cost more, but last longer. When replacing, make sure that the wizard uses quality glue for fixing – cheap glue can peel off over time, and the battery will “hang” inside the case.

5 Power controller damage: when the phone doesn't see charging at all

If the Redmi Note 8 Pro doesn’t respond to charging at all (the indicator doesn’t blink, doesn’t warm up, doesn’t make connection sounds), the problem may be the power controller, the chip that controls battery charging, which often occurs after:

• ⚡ Phone falls (especially at the corner where the controller is located).
• 💦 Moisture intrusion (even if the phone hasn’t sunk, condensation can cause corrosion).
• 🔌 Use of uncertified chargers with unstable voltage.
• 🔥 Overheating (for example, if the phone was lying in the sun for a long time or charged under load).

How to diagnose a controller breakdown:

1. Connect your phone to your computer through USB. If the computer does not see it, the problem is precisely in the controller or connector.
2. Try charging your phone when it's off, and if it's not charging, it's another sign of a controller malfunction.
3. Check if the phone warms up when you plug in the charger, and if so, maybe the controller is in short circuit mode.

⚠️ Warning: If the power controller is burned, do not try to charge the phone "through force" (for example, connecting directly to the battery).This can lead to fire or the phone finally fails.

Cost of repair:

• Replacement of the power controller - from 2500 to 5000 rubles (depending on the complexity of soldering).
• If the fee is damaged (for example, the tracks are burned off), repairs can cost up to 8000 rubles.

In some cases, the masters suggest that the controller be soldered from the donor board, but this is a temporary solution.

💡

If the phone is not responding to charging, but you are sure that the problem is in the controller, try connecting it to the charger on the phone. 10-15 minutes, and then press and hold the power button for a period of time 20-30 Sometimes it helps to wake up the controller.

6.Moisture and corrosion: what to do if the phone is wet

Redmi Note 8 Pro does not have water protection (IP-If the phone has been in water, beer or other liquid, the effects may not occur immediately, but after a few days or even weeks in the form of corrosion of contacts or short circuits.

Signs of moisture intrusion:

• 💧 The screen displays a warning, Charging suspended.
• 🔌 The phone will charge intermittently or shut down after a few minutes.
• 🔥 The body of the phone warms in the area of the connector or battery.
• 🎵 The speakers wheez or do not work (moisture could get there).

What to do if your phone is wet:

1. Turn off the phone immediately and remove it. SIM-map.
2. Don’t shake the phone – it can spread moisture inside.
3. Wet your phone with a dry wipe (don’t rub!).
4. Place your phone in a silica gel bag (those balls that are put in shoe boxes) on the phone. 24-48 Don't use rice, it's inefficient and can clog the port.
5. After drying, try turning on your phone. If it doesn't turn on or charge, bring it to the service.

⚠️ Attention: if the phone is already turned on after getting wet, but then stopped charging, it does not mean that it "dried up." Moisture could remain under the screen or on the board, causing gradual corrosion.

If the board has already developed corrosion (green coating on the contacts), you can try to remove it with isopropyl alcohol and a soft brush, but this is a temporary measure.

7 Software Limitations: Why Xiaomi is Blocking Non-Original Chargers

Xiaomi has introduced protection against the use of uncertified chargers in some models, including the Redmi Note 8 Pro. If you plug in a cheap Chinese charger, the phone can:

• 🚫 Display the warning This charger is not supported and block charging.
• ⚡ Charge 10 times slower (e.g. 1% in 10 minutes).
• 🔋 Turn off charging a few seconds after connecting.

How to get around the restrictions:

• 🔌 Use original Xiaomi chargers or certified ones (e.g. Anker PowerPort, Baseus).

If the phone refuses to charge from the original charger, but the original one works fine, it is not a breakdown, but a planned limitation, in which case you only have to buy a certified device.

Interesting fact: in some of the firmware MIUI There's a hidden charging test menu. To open it, type it into the dialer:

##284##

Here you can see the actual voltage and current flowing into the battery, and if the values are very different from the norm (for example, the current is less than 0.5A), the problem is precisely the charger or the cable.

8 Mechanical damage: what breaks when falls

The Redmi Note 8 Pro has a metal body that protects the insides well from scratches, but a fall impact can damage:

• 🔌 Type-C connector – contacts are bent or broken.
• 🔋 Battery – the internal plates may shift, which leads to short circuit.
• 📱 Fee – lanes are pulled away or chips crack (especially the power controller).
• 🔊 Wireless charging antennas (if you use an adapter for Qi charging).

How to understand that the problem is mechanical:

• The phone stopped charging after the fall (even if there is no external damage).
• Type-C connector backup or cable does not come tightly.
• There are dents or cracks on the body (especially in the lower part where the connector is located).
• The phone does not turn on at all, but when connected to a computer is defined as Qualcomm. HS-USB QDLoader 9008 (This is a sign of bootloader damage).

What to do:

1. If only the connector is damaged, it can be replaced by 1000-1500 ruble.
2. If the fee is broken, the repair will cost 3000-8000 RUB (depending on complexity).
3. If the phone doesn't turn on after a fall, don't try to charge it - it can aggravate the problem.

⚠️ Warning: If after a fall the phone starts to warm or smell like a burn, immediately disconnect it from charging! this is a sign of a short circuit that could lead to a fire.

💡

If the phone stopped charging after the fall, but looks whole, it does not mean that there is no damage. Inside, the contacts may have gone off or the chips cracked.
