Can a cheap wireless charger damage the phone or degrade battery faster?
Recently got an iPhone XR, been very happy with it so far. One of the best LCDs I’ve ever used. Since it was at Costco, they have a bunch of iQ brand accessories, and I wanted a wireless charger so I picked up one there for $50. I’ve noticed the charger creates a small whining oscillating sound, which I’m assuming is coil whine. Can using a cheap wireless charger like this do anything to my phone? Is it worth investing in a higher quality charger to protect the phone? I don’t mind the noise, it just worries me slightly.
