I have one of those Anker Wireless Charger, 313 Wireless Charger stands and had the phone on the charger.

I rarely have it on the charger when on a phone call but recently I left it on there and answered a call on speakerphone.

My caller mentioned having a very scratchy connection on her side ... until I took the phone off the charger.

I then bought a stand that would take the Apple MagSafe charger. No scratchy issues with that charger.

Not sure if it was that call, the charger, the wall charger, the cable ..... but it got me thinking of dirty power and clean power charging, a nice clean frequency out of the charging system.

Is it known which are the cleanest chargers/cables/wall adapters out there?

Depends on where you live and the connections inside your house that determine a lot of those things. Audiophiles will often talk about these topics but for something like you’re talking about is going to boil down to the charger quality and interference.

I wouldn’t get too worked up about it. You can buy products that claim to cleanup frequencies/voltage that come from the wall but a lot of them are overpriced and do very little, if anything. You would have to buy some very expensive equipment to do it right.
