Going back to our troubleshooting, here are the things you need to do to make your Galaxy S9 charge normally again…
- Make sure that the fast-charging feature is enabled.
- Perform the Forced Restart to refresh your phone’s memory.
- Turn off screen while phone is charging.
- Make sure the phone isn’t heating up too much while charging.
- Try updating the firmware if possible.
- Try turning the phone off while charging.
- Bring phone back to store or shop so the tech can check it for you.
I know these steps are pretty self-explanatory but let me briefly explain why you have to do them.
So first is to make sure that the fast charging feature is enabled. This must be the first thing to do especially if you’ve changed some settings recently. The fast charging feature may have been inadvertently disabled. So, follow these steps to check on it:
- Open the Settings app.
- Tap on the Device Maintenance option.
- Look at the bottom left and tap on the Battery icon.
- Tap the 3-dot menu icon at the top right of the screen.
- Choose the Advanced Options option in the drop down menu.
- Touch the Fast Cable Charging option to flip the toggle off and on.
After making sure that the fast charging option is enabled and the phone is still not charging fast, the next thing to do is the Forced Restart to refresh your phone’s memory. To do this, press both the volume down and power keys at the same time and hold them together for 10 seconds or more. Your phone will reboot like it normally does but it’s memory is already refreshed so try to see if the fast charging is now working.
Other things that need to be done is to turn off the screen while the phone is charging because if the screen is powered up, the feature may not work. Also, make sure that the phone isn’t heating up fast or overheating while it’s charging because that would also prevent fast charging. You must also try turning the phone off completely while it’s charging to know if the fast charging feature works because if so, then the cause of the problem could be some apps that run in the background.
If possible, check if there’s an update available because there could be an issue with the current firmware. As I said, it also plays a big role in the charging process and updates are Samsung’s way of fixing any firmware-related issues.
After all this and the phone is still not charging fast, backup your files and data, reset your phone and then bring it to the store or shop so that a technician can check it up for you. The problem could be hardware-related.
