Fast charge weird issue

Hi there,

I have a strange issue with my S10+ Exynos. Actually if I enable fast charging, it gives me a time to charge completion.
I unplug the phone, I disable fast charging, I plug the phone again and it gives me a time to completion of 20 -25 mns more.
But after 10 seconds, it comes back to the same time as fast charging without doing anything.
What can explain this behaviour ?

Fast charge only works, when the screen is off. That means, if you turn on your screen, to see the ETA charging time, it will display the time with screen on.

Try to enable AOD and realy measure the charging time eith and without fast charging.
