I am having an issue with charging my S21 Ultra on samsung wireless charger Trio (the one that came with the phone as part of samsung offer).
When phone is plugged in via cable, all works as it should. However when I leave the phone on the Trio charger in the evening, it would say "charging 2h 30mins remaining" however by morning it would still not be fully charged, that would be at least 8hrs on the Trio. All fast and super fast options are enabled. The phone is left on Trion with screen off. There would be buds pro also charging nearby (and they charge just fine). The phone is brand new, got it delivered 3 weeks ago.
I did some additional test runs and the phone reports time that is never achieved charging on Trio.
