A growing number of Galaxy S20 Ultra and Galaxy Note20 Ultra users (via Reddit, Samsung) are complaining about wireless charging not working properly on their device. The problem is that keeping the phone on the wireless charger does not charge it at all. The issue seems to be affecting customers for over a month now and seems to have started after a firmware update.
The issue primarily seems to be affecting Galaxy S20 Ultra and Note20 Ultra customers who are using a third-party wireless charger. The official Samsung charger is still able to wirelessly charge the affected units wirelessly without any issues. Affected Galaxy S20 and Note20 Ultra users have tried a reboot, factory reset, and changing wireless charging-related options in a bid to fix the issue to no avail.
A recent firmware update from Samsung did fix the wireless charging issue for some Galaxy Note20 Ultra users, but there are still others for which the update did nothing. The issue also seems to be only affecting the Ultra variants of the Galaxy S20 and Note20, with wireless charging working fine on the other variants.
The problem seems to be affecting a limited number of Galaxy S20 Ultra and Note20 Ultra users which is perhaps why it has slipped under Samsung's radar. With the issue now getting the media spotlight, it is likely that Samsung will take notice of it and roll out a firmware update to fix it.
