Fast charging has stopped working - S20 Ultra

[postmodernronin]

No clue why. All it does is regular charge since like 2 weeks ago I'm noticing yesterday 

I dusted the ports, made sure the cables were connected properly. I even booted the phone into safe my mode and wiped cache partition

Battery saver is disabled and all of the battery settings for fast charging are enabled in the settings

Do I have to factory reset or am I missing something?

I had the same thing happen to my s22 ultra after the update a week ago. Dies so fast and will initially say fast charging when plugging my phone in but after 2 seconds turns to slow charging and is sooooooo slow. Takes over 24hrs to fully charge. I bought all new cables and blocks for fast charging. No change. Cleaned my charging port. No change. Changed the outlets. Nothing. Reset my phone. Still nothing. Wireless charging does work so it's not the battery itself.

All the options for fast and super fast charging or selected on. And I double checked any 3rd party apps that could be causing a problem.

I've done it all. I am so frustrated.

My phone dies so fast. Even starts dropping in battery percentage while I use it while it's plugged in. Absolutely ridiculous.
