Tips to avoid slow charging issues

1- Don’t overcharge

Overcharging can be really tough on your phone when it comes to battery life and charging speed. It can also heat-up your device making it uncomfortable to use afterward.

2- Use a good quality charger

When choosing a charger to charge your Galaxy Note 9, always make sure that the quality of your charger is good enough and meets the required standards. Besides the charger, make sure the USB cable is not affected or torn.


1- Restart the device

The easiest and quickest solution for getting rid of the slow charging problem is to quickly restart your phone. Your phone may be having some bugs at that particular moment, and restarting may resolve some minor bugs.

To restart your phone, simply hold down that lock-screen button for a split second and wait for the power options to pop up. Once they do, tap on ‘Restart’.

2- Replacing your charger

Samsung Galaxy Note 9 comes with a fast-charger inside the original box. The purpose of this fast charger is to make sure your phone gets charged in less than a couple hours, so you don’t have to wait for a long time which gets pretty annoying.

However, if there are some issues with your charger, it can lead to a significant reduction in charging speed. Try changing the charging cable, or replace the charger as a whole. You can easily get a new one from the market or from a trusted online seller.

3- Enable fast charging mode

Samsung Galaxy Note 9 comes with a built-in fast charging mode. This mode doesn’t come in all Samsung models as not all the phones have such gigantic batteries. If the fast-charging mode doesn’t start right after you plug in the charger in the power socket, check if it is enabled.

To do that, go to settings. Click on ‘device management’. Select ‘battery’ which will open a new window. Find advanced options and enable fast charging.

4- Turn on safe mode

The Galaxy Note 9 has a safe-mode option available too. Turning safe-mode will put the background apps to sleep. This was, you’ll see if one of the third-party apps is causing the charging issues. You can then uninstall the apps one by one until the issue is gone, or you can perform a factory reset. To enter the safe mode:

  • Press and hold the Power button
  • Tap and hold Power off option
  • Tap Safe mode

See how your phone behaves in a safe mode. Start charging it. If it all seems fine, then one of the third-party apps you have on your phone is causing the problem.

5- Do a factory reset

Your phone might be having some junk inside the software that can possibly cause slow charging issues. Doing a factory reset can resolve this if the above methods don’t work. To do a reset, just go to settings and find the ‘reset to factory settings’ option at the very bottom of the list. But make sure that you create a backup because the factory reset deletes everything you have on your phone.

6- Consult customer service

If the issue isn’t solved, try contacting customer support. If you bought a new Galaxy Note 9, you usually get a one-year warranty. So, if there are any issues during that time period, you can contact the company and they will do the repairing job for you free of charge.
