Since the latest update I am unable to fast wireless charge my S20.  All 3 chargers I own were fine until the update was installed and now I get a message to show that the chargers are not compatible.

Is anyone else having issues and is there a fix in place?

Hi @Kojak_1984 

 

Are you three chargers official Samsung chargers  ?

Is fast charging still toggled On in your phones settings  ?

If it is then toggle it off, soft reboot by turning the phone off and on and then toggle fast charging back on and then see what happens.

Unfortunately I have known 3rd party chargers experience issues after the phone has updated. 

This has happened to iPhone's I've owned previously too.

Can you try an official Samsung charger  ?

I don't use fast charging. It's a terrible idea. It damages the battery. These types of battery should be charged at a maximum of 2A. Sure, it might not be convenient, but hey its better to be safe than over stress a battery that can be hazardous

Hi @GreyMatter 

I only use fast charging on my Samsung phones if I ever  end a quick boost of juice.

I also use Samsung Desktop chargers that have a cooling fan installed to help with the increased heat produced.

And if a case is on the phone remove it to help the phone get rid of the heat more effectively is my advice.

The phone's and batteries are intelligent and manufactured by Samsung to be able to cope with fast charging or Samsung wouldn't be able to provide it.

I prefer to normal charge and carry round a power bank.
