The iPhone 7 and earlier all had an aluminium back no issue. Changed to glass from the 8/X onwards for wireless charging.

iPhone 7 placed the antenna on the rim, the area where there is a bit of plastic. For years iPhone wireless & wifi connections are somewhat weaker than other phones, I suspect it's because the metal back.

Wireless charging is also RF btw.
