How to Fix Fast Charging Not Working

Sometimes fast charging might not work on your phone if there is a weak power source. So, the first thing you can do to fix the issue is to charge your phone from a different charging outlet.

Check the Charging Cable, Adapter, and Port

If your charging cable, adapter, or port is damaged, your Fast charger will not work. Your phone is at risk if either of them is broken or wet. Please refrain from charging with such a charger. You can try replacing a cable or buy a new charger. However, while buying parts of the charger, i.e., an adapter or USB cable, you must make sure that it is compatible with your phone for fast charging. 

Clean Charging Port

Fast charging might not support if your charging port is full of dust or lint you’re unaware of. The debris can cause a hindrance to the device connected with the charger. Thus, you can check your charging port to see if it is debris free. Although, cleaning it is the best solution as some dust might not be visible with our eyes. So, follow the steps.

Before cleaning the charging port, please consider the following things:

  • Avoid using wet objects to clean the area.
  • Refrain using a toothbrush as its bristles might get stuck.
  • Don’t pour or use abrasive cleaning liquids, i.e., bleach on the surface
  • Avoid blowing into the charging port with your mouth. You might accidentally wet the device while blowing and make it worse.
  1. Switch off your Phone and use another phone to turn on the Flashlight to see the charging port properly.
  2. Then, you can either use a Soft Cotton Swab or Bulb Syringe to clean the charging port. 
  3. You can also use a Toothpick to pull out debris. But, please be cautious not to break the toothpick in the port.
  4. After cleaning, Wait for some time and turn on your phone. Try plugging your phone in a charger and see if it works.                                                                                                                        

Try Using a Different Fast Charger

Your fast charger will not work if there is an issue with your charger. Sometimes, there might be damage to the charger that might not support your device. So, in such a case, you can try using a different fast charger. 

Check Device Compatibility

Some devices, like iPhones, do not have fast charging in their original charger. So, you can look up your device model on Google to know if it is compatible. You can purchase a different fast charger.

While getting a new one, be aware that your Fast Charger might not work if you are unaware of using a fake charger. It stops your charger from working as well as degrades your battery. So, be cautious and use only a certified charger.

1- Navigate to phone Settings > Battery and Device Care

2- Tap on Battery > More Battery Settings

Close All Active Apps

If there are active apps in the background when you are charging your phone, it might slow down, especially if you are using streaming apps while charging. You must force quit all active apps and refrain from using any while charging your phone. 

Disable Wi-Fi or Mobile Data

If you are connected to Wi-Fi or mobile data, it will slow down the fast charging speed. Your battery is also at risk as it drains your battery status. So, you must keep your phone idle and disconnected from an internet connection.

You can tap on the Wi-Fi or Mobile Data icon from the control center to disable it. You can also turn on Airplane Mode to enable fast charging.

Turn On Safe Mode

Active third-party apps that you might not detect can be the reason your fast charging is not working. So, you can turn on safe mode to block such apps and improve your charging performance speed. To turn on safe mode, you must go to Android Recovery mode.

2- Then, press and hold the Volume Up and Power Button together. Release once the Main Menu or Recovery Mode appears on your screen.
