How to Fix Slow Charging on Xiaomi Phones: Complete Guide

 Are you experiencing slow or inconsistent charging on your Xiaomi, Redmi, or POCO smartphone? You’re not alone. Many users face this problem, which can be caused by dirty USB ports, faulty cables, low-quality chargers, or aging batteries.

In this guide, we’ll explain the main reasons why your Xiaomi phone charges slowly and provide practical step-by-step solutions to restore fast and stable charging.

🔹 Why Xiaomi Phones May Charge Slowly

Several factors can lead to slow charging on Xiaomi devices:

  1. Dirty or blocked USB-C port – Dust, lint, or debris can block the pins and reduce charging efficiency.

  2. Faulty or low-quality charger and cable – Unstable voltage or damaged wires can limit current flow.

  3. Battery degradation – Older batteries lose efficiency over time, resulting in slower charging.

  4. Software limitations or MIUI bugs – Some system updates or battery optimization settings can affect charging speed.

  5. Overheating – Charging slows down automatically if the phone becomes too hot to protect the battery.

Understanding the cause helps you apply the most effective fix and avoid damaging your device.

🔹 1. Clean the USB-C Port Carefully

One of the most common reasons for slow charging is a clogged USB-C port. Even tiny dust particles can interfere with the connection between your cable and the charging pins.

How to clean your Xiaomi USB-C port safely:

  1. Turn off your phone before cleaning.

  2. Blow gently into the port to remove loose dust.

  3. Use a wooden toothpick, soft brush, or small anti-static brush to remove dirt from inside the port.

  4. Avoid metal objects or liquids, which can damage the pins or short-circuit the device.

After cleaning, reconnect your charger and check the charging speed. Many Xiaomi users notice immediate improvement after this simple step.

🔹 2. Check the Charger and Use a High-Quality Cable

If the port is clean but charging remains slow, the charger and cable quality should be examined.

Tips for choosing a reliable charger:

  • Inspect the cable for frays, bends, or cracks. Damaged cables can reduce charging speed or cause intermittent charging.

  • Use original Xiaomi chargers or trusted brands like Aukey, UGreen, or Anker.

  • Avoid cheap, unbranded adapters, as they often deliver unstable voltage that may harm your battery over time.

✅ Using a high-quality charger and cable ensures your Xiaomi phone reaches its maximum supported charging speed.

🔹 3. Test Battery Health with the Ampere App

If cleaning the port and using a quality charger doesn’t help, your battery might be the issue. Over time, lithium-ion batteries degrade, reducing charging efficiency.

How to check battery health:

  1. Download the Ampere app from Google Play.

  2. Open the app while charging your phone to monitor:

    • Current charging rate (mA) – Indicates how fast your battery is charging.

    • Battery temperature – Should stay between 26°C and 40°C for optimal charging.

    • Battery health – Shows whether the battery is in good condition or deteriorating.

💡 Tip: If the current is consistently low or fluctuates widely, it might indicate a weak battery or damaged charging circuit, which needs professional attention.

🔹 4. Software and MIUI Settings That Affect Charging

Some MIUI features can unintentionally reduce charging speed:

  • Battery Saver – Limits charging current in some cases.

  • MIUI Optimization – May restrict background activity or fast charging under certain conditions.

  • System updates – Occasionally introduce charging-related bugs.

Solutions:

  1. Restart your phone – A simple reboot can fix temporary software glitches.

  2. Disable Battery Saver during charging:

    • Go to Settings → Battery & Performance → Battery Saver → Turn Off.

  3. Check MIUI updates – Ensure your phone is running the latest firmware, which may fix known charging issues.

🔹 5. Avoid Overheating While Charging

High temperatures automatically slow down charging to protect your battery. Common causes include:

  • Using the phone while charging (gaming, streaming).

  • Charging under direct sunlight or hot environments.

  • Low-quality chargers generating excess heat.

Tips to prevent overheating:

  • Remove the case while charging to improve heat dissipation.

  • Avoid high-intensity apps during charging.

  • Use original Xiaomi or certified fast chargers, which regulate temperature efficiently.

🔹 6. When to Visit a Service Center

If your Xiaomi continues to charge slowly after trying all of the above steps, it may indicate a hardware issue:

  • Extremely slow or intermittent charging.

  • Phone fails to recognize the charger.

  • Battery temperature is abnormally high.

  • Charging stops randomly, even with a good cable and port.

In these cases, visit an authorized Xiaomi service center. Technicians can check:

  • Battery health and efficiency

  • USB-C port integrity

  • Charging circuit and motherboard functionality

This ensures your device is repaired safely without risking further damage.

🔹 7. Extra Tips for Faster Charging

  • Use original fast chargers – Xiaomi devices often support Quick Charge or TurboCharge, which requires compatible adapters.

  • Charge with the screen off – Reduces energy consumption, allowing faster charging.

  • Avoid third-party fast chargers with unknown specifications.

✅ Following these tips ensures stable and efficient charging while protecting your battery lifespan.

🔹 Summary: Quick Steps to Fix Slow Charging on Xiaomi Phones

StepAction
1Clean USB-C port – Remove dust, lint, and debris safely.
2Use original or high-quality charger and cable – Avoid unbranded adapters.
3Check battery health – Use Ampere app to monitor charging rate and temperature.
4Optimize MIUI settings – Disable Battery Saver, check updates, reboot.
5Prevent overheating – Remove case, avoid heavy apps, and charge in a cool environment.
6Seek professional help – Visit an authorized service center if the problem persists.

By following these steps, you can restore normal charging speeds, protect your battery, and ensure a longer lifespan for your Xiaomi, Redmi, or POCO phone.
