Slow charging is a common issue especially if you’re used to having a smartphone that only takes an hour or two to replenish a huge battery. By default your Samsung Galaxy Note 9 should use its fast-charging feature the moment it’s connected to its charger regardless whether you’re using a wired or wireless.
Samsung Galaxy Note 9 can charge its battery from 0 to 100% in approximately 2.5 hours. Compared to other smartphones, that’s already considered fast and considering it has a huge 4000 mAh battery, it’s amazing the device can charge it up that fast and could last another couple of days before requiring another charge.
However, if the charging process takes longer than usual and you’re using the original charger, then we can already consider it as a case of a slow charging. That’s that purpose of this post; to address slow charging issues. However, if you’re new device isn’t charging at all, then read our article that deals with a Note 9 that’s not charging out of the box.

What to do if your new Samsung Galaxy Note 9 charges so slow?
The following easy procedures will be able to help you determine what the problem is. If it’s fixable on your end, then your Note 9 should be fast charging after this. If not, that’s a valid reason to bring your new premium device back to the store and have a technician take a look at it. It might be replaced if the tech can’t make the device charge normally again. With all that being said, this is what you need to do…
Make sure fast charging feature is enabled
While this feature is enabled by default, it’s possible you have changed some settings in your phone. So, before anything else, check the settings to know if the fast charge feature is enabled or not. Go to Settings → Device maintenance → Battery → More option → Advanced settings → Activate Fast cable charging option.
If it’s already enabled, try to do the forced reboot to refresh your phone’s memory and reload all apps and services. It’s also possible that the problem is due to some glitches which occur from time to time. To do this, press and hold the volume down button and the power key simultaneously for 10 seconds. Your phone will reboot like it usually does but more often than not, it fixes almost all minor problems like this. But if the slow charging issue continues, then move on to the next procedure.
Try charging your phone while it’s powered off
There are some prerequisites before you can enjoy the fast charging feature like the screen should be turned off while charging and it should not heat up because it will automatically disrupt the feature.
When your phone is powered down, all prerequisites are already done so if there are no other issues, your phone should be able to fast charge. It’s very important that you try this procedure as it will determine if there’s a problem with your phone or not.
I suggest you try using the wired charger while doing this because it works perfectly, it most likely that wireless charger would also work without a hitch. If the phone continues to charge very slowly even when it’s powered off, then you have no other choice but to do the next procedure.
Reset your phone and find out if it charges fine after that
The firmware plays a very important role in the charging process. If there’s an issue that affects some services, then you can expect problems like this to occur every now and then. To address or rule out such possibility, you need to reset your phone. It’s also a preparation just in case the problem continues to have charging issues after it. Make sure to backup your important files and data as they will be deleted during the process. After the backup, follow these steps to reset your phone:
- Back up data on the internal memory. If you have signed into a Samsung account on the device, you have activated Anti-theft and will need your Samsung credentials to finish the master reset.
- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times to highlight ‘wipe data / factory reset’.
- Press Power button to select.
- Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
- Press Power button to select and start the master reset.
- When the master reset is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
After the reset, try charging your Galaxy Note 9 while it’s powered off. If you think it’s still slow, then it’s time to pay Samsung store a visit and have the new device checked.
