As a heavy phone user (which is pretty much everybody these days) I have a magnetic holder in my car, and one on my home desktop. There is a permanent plate on the back of my iPhone X which is required to mount magnetically. I've had this configuration for over a year, never had an issue. I also have one on a backup iPhone 6+, the same thing, never had an issue. It's super convenient versus the mounts with the wings to grab the phone. Hope this helps.
