What are the possible causes for fast charging not working

You may wonder what is wrong with the fast charging and why it doesn’t work on your Samsung Galaxy S23. 

As we know, fast charging only works if these conditions are met:

  1. If you have a fast charger (15W for fast charging), fast charging supported USB-C cable, 
  2. If your phone’s power pin is not defective (broken), and
  3. If the software works flawlessly

This means these 3 are the things that you should look at if fast charging is not working on your phone.

So it could be the charger, the cable, power settings, and other system-wide issues affecting the fast charging on your device.

So before getting into the solutions, let’s do some basic checks, starting with your charger.

Fix 01: Check the Fast Charger and Cable

As we said earlier, the first step is to check the fast charger and cable.

Check if your charger is original and compatible with Samsung’s fast-charging power standards. If it cannot produce at least 15W, your Galaxy S23 won’t detect and show “fast charging” on the screen.

It is also worth mentioning that if the cable you are using to charge your device cannot transmit enough power, then having a compatible charger won’t fix the issue. So ensure both the cable and charger support fast charging.

Fix 02: Enable Fast Charging

Did you know that fast charging can be disabled through settings? Another potential culprit of fast charging not working on your Samsung Galaxy S23 could be not enabling the fast charging feature. 

So you need to check your device’s power settings, as it may require that you manually turn it on.

Here are the steps that you should follow:

  1. Go to Settings.
  2. Select on Battery and Device care.
  3. Tap on Battery.
  4. Scroll down and tap on More battery settings.

Fix 03: Enable Super Fast Charging

Enabling Super Fast Charging on the Samsung Galaxy S23 is another way to get your device charged with super fast charging, instead of the traditional fast charging feature.

It is because if your charger supports 25W power output, then you will be able to fix the issue by enabling super-fast charging.

The steps you have to take are similar to enabling fast charging:

  1. Go to Settings > Battery and Device care.
  2. Tap on Battery.
  3. Scroll down and tap on More battery settings.
  4. Turn on Superfast charging.

Fix 04: Do a Software Update

If the above solutions did not work, maybe it is the system that is causing the fast charging not to work. To fix it, you can do a software update as it brings new features and bug fixes that could help with the issue at hand. 

To update the software, do this:

  1. Go to Settings.
  2. Tap on Software update.
  3. Tap on Download and install.
Download and install

Fix 05: Clear the System Cache

Once you have done the software update, you need to clean the system cache to remove corrupted and outdated cache files. This helps your system to run smoothly so there won’t be any glitches or problems preventing fast charging from working.

To do this, you have to boot your device into recovery mode. If you don’t know, here is how to do that:

  1. Turn off your device.
  2. Plug a USB cable into the device.
  3. Press and hold the Power key + Volume up keys for a few seconds. When the recovery menu appears, release the keys.

After that, follow these steps to clear the system cache (wipe cache partition):
