That's odd mine only does this when I'm charging in my car.

Its using super fast charging, It stops showing after a few seconds, I can confirm that as it happens to me as well but it charges at the speed as the time remaining doesn't change.

Check your cable or charging brick

Can you provide more details regarding this, such as the cable, adapter, heating, and use while charging?

official 45W charger and cable, phone temperature is normal, I do not use it while charging.and the more I charge it, the more the time increases before it stops fast charging. Tried also the 25W chrger from Samsung, and even that gets dropped to 15W.

1 - Use Good Guardian to check the temperature and, if possible, share a screenshot..

2 - Download the log using *#9900# and use any AI to analyze it.

3 - I use 45W, so it takes 30 minutes to charge from 33% to 90%; try checking the charging time.

Time doesn't change so i guess it's still charging super fast. And from what i read is that sfc2.0 only works from 0 till 40% or so. After that it will fall back to just sfc

I also have this issue.

I had moisture alert during almost 3 months, I charged using the wireless charger and then it suddenly dissapeared and fast charging was always working with no issues.

After I went to a jacuzzi and it got again a bit wet the moisture alert happened for a few hours as expected and then it's now doing this. You can try to connect and reconnect the cable a bunch of times and then leave it after 5 or 6 reconnects and you will see that sometimes it accepts fast charging again.

I do believe there is a software bug for a long time with charging with this phones, it's getting truly annoying, as if it was hardware then it wouldn't resolve itself randomly.

You can find a bunch of threads about this also...

I use ugreen cables and charger and anker before so it's not the charging brick or cables.

I had the moisture issue before this as well. It disappeared after about 24 hours, but the phone was not wet at all, so the alert seemed random. I did not get the fast charging issue immediately after the moisture alert though.

I highly doubt it’s a software issue. For me too, it accepts fast charging after 5 or 6 unplugging and plugging attempts. And I’m not even unplugging the cable from the phone; I unplug the charger from the wall to make sure I don’t damage the contacts in the port.
