I bought a witeless magnetic battery recently, and what quickly turned me off was that it charges at ~2/3rd efficiency and speed than its wired mode. Also heats up my phone battery way more, so I just snap it to my phone and use the short and unobtrusive usb-c cable to charge it instead.

Now, if I was changing phones every year or two and I didn’t care about keeping its battery life - sure, I’d use the wireless charging without worries, although it will still be slightly slower than wired (but still fast charging anyway).
