Z Fold 4 Fast charging issues

[NatureBoiyy]

Recently just got a Z Fold 4, when I plug my phone in to charge it doesn't fast charge whatsoever. It'll say fast charging for 2 seconds and then it will revert back to just regular charging, doesn't matter what cable or charger I use it's all the same, anyone else have this issue?

@NatureBoiyy No problem fast charging my Fold 4. Often the charger or cable is at fault. Have you tried swapping out both?

Yea I've tried multiple cables and different bricks. It'll display "Fast Charging" then it just reverts back to just "Charging" Idk what the problem is

My Fold 4 does show fast charging for a brief moment and then just shows changing and time. I did tests by turning on/off fast charge in settings and charge time increases. This makes me believe that device is charging fast.

Mine does the same as you describe. I'm using a Samsung charger and the cord it came with. I had no problems super fast charging my previous phone

I have exactly the same problem the phone with fast charge but it doesn't show

I've noticed that my new fold 4 will start fast charging for a few seconds only after that it will just charge. No idea why even when fast charge is enabled

i've tried different chargers and still nothing

Same thing is happening to me. I've tried the 45w charger thinking that the 25w wasn't working properly. It was the same outcome. I even tried my other cables and nothing. This has to be a software bug
