Hi everyone, I bought the phone a few days back and have used multiple super fast chargers with a 5a cable to try to charge but as soon as I connect the port it goes from super fast charging to just charging. In Battery it shows there is a super fast charger connected but any idea why this happens? Does the s23 ultra not support super fast charging or is this a bug in these new phones? It's driving me insane.

I had this issue with the anker powerline charging cable, replaced twice under warranty as it works for the first couple of weeks before refusing to super fast charge. Bought some Iniu cables and have had no problems since.

No problems with my Samsung branded charger using branded high quality cables.

Super fast charging can be very quirky. I've a few 45W fast chargers, but only the official Samsung one allows consistent super fast charging on all my Samsung devices. It seems as though more recent devices seem to break the Super fast charging with 3rd party chargers, although the S23 Ultra does seem to charge almost the same speed whether it be 2.0 or not.

The S23 Ultra does support fast charging and Superfast charging it the charging notification is silly

When you first plug it in it shows super fast or super fast 2.0 depending on the charger for a few secs then changes to charging.

It still super fast charging but notifications only shows charging

This article explains it all. I know the article is for the S22 but it's the same reason for the 23 too.

I had this issue, it wasn't super fast charging when it switched to charging as the time remaining changes from about an hour to almost 2 hours.

The ring colours simply indicate superfast charging (green) and superfast charging 2.0 (blue).

What ring colours, where? When I plug my s23 ultra to charger, it shows at first superfast charging text. But the real problem is that on some cases the charging is very slow and most cases fast. Using the same Samsung charger and same cable.
