For quite a while now my s21 ultra has been charging at slow speeds and on a previous post of mine complaining about the same thing, I was told that my battery was the problem (which played a part) so I decided to change it. I've now changed and my phone still decides to charge slow and I've got a screenshot for anyone who wants to see. Btw I am using a Samsung 25W charging brick and cable and I've got super fast charging on.
