Anyone else recently had to go back to an old charger because super fast charging isn't working properly? Tried two different chargers and cables and wireless too. Software up to date and turned on in battery settings.
Mine has played up in the past but not recently. My only suggestion is to carefully clean the charging socket and slot as a bad contact usually prevents fast or super-fast charging experience. This is after ensuring you are using the correct charger and charging mode 👍🏻
Funny enough, I'm experiencing sight of the same problem, my wireless charger is fast charging and when I place my phone on it says fast wireless charging, then two minutes later changes to charging it keeps doing this for many times I don't know what is going on here try just contacting Samsung. I'm sorry that I cannot help too much.
