My s23 ultra is charging very slow

[Haytch]

This has happened to my phone several times in the past and also happened to my s22 ultra..

My phone will not super fast charge anymore. I have done pretty much everything. It doesn't even fast charge, never mind super fast charge. I've changed cables, changed sockets, changed plugs and nothing seems to work. 

I have also tried to charge another device and guess what. It showed super fast charging. Why has this suddenly happened with my s23 ultra. Can Samsung please resolve this issue. It definetly has to be a software issue since the last update.

@Haytch  Ensure that there is no moisture or debris in the charging port and that you do not have many apps running when charging.  Have any 3rd party apps recently installed as that can cause a conflict.

Did you clear the cache partition after the update as is advisable,temporary cache files are deleted but Data is intact. 

1. Turn off the device.
2. Connect To Computer or plug in USB-C Headphones , Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release all three keys.
4. Wait until the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.

Can also repair apps from the Same Recovery Menu.   Otherwise can send an Error Report via Samsung Members-Support-Send Feedback-Error Reports.  A Factory reset would be the last resort (obviously ensure Data is backed up).
