How to troubleshoot Galaxy S9 Plus that’s charging very slowly
Before you begin to troubleshoot system errors on your device, check for any pending app updates to install. Usually when a new firmware update is implemented, apps developers likewise roll out necessary updates for their app to remain compatible with the latest Android platform running on the phone. Apps that are already out of date may tend to misbehave and trigger other issues to occur. If all your apps are updated but your Samsung S9 Plus is still charging very slowly, then you may now continue and start performing these workarounds.
First solution: Reboot your phone (soft reset).
A soft reset might be all you need to rectify an update glitch that might have triggered the charging system to go rogue or not perform as expected. If you still have enough power left on your phone, try to reboot your device or perform a soft reset with these steps:

- Press and hold the Power button.
- Tap the option to Power off.
- Tap Power off again to confirm.
- After about 30 seconds, press and hold the Power button again until your phone boots up.
Alternatively, you can do a soft reset using the hardware keys with these steps:
- Press and hold the Power and Volume Down buttons simultaneously for up to 45 seconds.
- Release both buttons when the Samsung logo appears.
Both of these restart method work the same without affecting your data and personal information saved in the internal memory of your phone.
Second solution: Force all background apps to quit.
Some apps can also go rogue when a new update is installed and background apps are no exception. Keeping more apps running in the background is also one of the causes of rapid battery draining especially if any of these apps is crashing or gets corrupted after the new update installation. To rule this out from the possible triggers, force all your background apps to close then try to charge your phone again without these apps. Here’s how you do it:
- Touch and hold the Recent apps key at the bottom left corner of your phone.
- Swipe an app to the right to close app individually.
- Or tap the X icon.
- If there are multiple apps running in the background, tap the Close All option instead. Doing so will quit all background apps at once.
Third solution: Reset all settings on your Samsung S9 Plus.
Software updates especially major firmware versions may tend to override your settings and when this happens there’s a tendency for errors to occur. Your phone might have set to consume a lot of power that it may appear to you that your device is charging very slowly but actually there’s just something in the system that causing rapid battery draining. To make sure this isn’t the culprit, performing all settings reset can help. Here’s how it’s done:
- Swipe up on an empty spot from the Home screen to open the Apps tray.
- Tap Settings.
- Tap General Management.
- Tap Reset.
- Select the option to Reset settings.
- Tap Reset settings to continue.
- If prompted, enter your device credentials like PIN or password.
- Then tap Reset settings again to confirm reset.
Your phone restarts when the reset is finished. But if that’s not happening, then manually trigger your device to restart. Just follow the above steps to perform a soft reset on your Samsung S9 Plus.
Fourth solution: Wipe cache partition on your Samsung S9 Plus.
Another possible solution to charging problems that are attributed to faulty updates is to clear the cache partition. Should there be any temporary files (cache) that gets corrupted after the new update is installed, wiping them will most likely fix the problem. Here’s how it’s done:
- Turn off your phone.
- With your device turned off, press and hold the Volume Up, Bixby (Home), and Power buttons simultaneously for a few seconds.
- When the Android logo appears, release all three buttons.
- After a few seconds, you should see the Installing system update message on the screen and then the Android system recovery menu shows up next.
- From the Android system recovery menu, navigate to the options using either Volume Up or Down buttons and confirm selection with the Power button.
- Press the Volume Down button several times to highlight wipe cache partition from the given options.
- Then press the Power button to confirm selection.
- Press the Volume Down button to highlight Yes then press the Power button to confirm.
- Wait until your phone is done wiping cache partition and when it’s all done, the Reboot system now option is highlighted.
- Finally, press the Power button to restart your device.
Unlike a master reset or factory data reset, wiping the cache partition does not delete any of your personal data and customized settings on your device.
Fifth solution: Factory data reset/master reset your Samsung S9 Plus.
If wiping the cache partition doesn’t help, then you may now resort to a master reset or factory data reset. This will wipe everything from your device including your personal data along with any bugs and malware that might have ruined the charging system and inflicted slow charging issue on your phone. Should you wish to proceed, be sure to back up all your important data for safekeeping. And when everything is set, follow these steps to master reset your Samsung S9 Plus through settings menu:
- Open the Apps tray.
- Then tap Settings.
- Tap General Management.
- Tap Reset.
- Select the Factory data reset option.
- Scroll down to the bottom of the screen then tap the option to RESET-> then DELETE ALL.
- Tap the option to CONFIRM master reset.
- If prompted, enter your credentials to unlock screen and/or verify your Samsung account.
After the reset, try charging your device again and see if it’s now able to charge at an expected pace.
If all prior methods failed to offer an ultimate solution and that your Samsung Galaxy S9 Plus is still charging very slowly, then report the issue to your carrier or Samsung Support for them to tag it among other post-update issues to be addressed in the next update.
Alternatively, you can have your phone diagnosed by a Samsung technician at the service center for any possible indications of hardware damage. Also take your charger with you so that the technician can assess the charger too. It’s possible that what you’ve got is a defective charger and that’s why it’s unable to render the right amount of power to charge your device as fast as it should.
