Many professional service firms do not allow BYOD. Depending on your job, you may end up with per-mandate phones.

I once had to take four phones with me for a short while and ended up looking like an absolute clown, stacking them on the restaurant table.

Not having to do that is a privilege.

Why did you stack your phones on the table?

I thought it was funny putting the camera stickers on multiple phones at a nightclub entrance.

nfc or qi attack available through stacking, not a good idea.

or even speaker to mic data exfiltration.

or screen flickering against another light sensor in a dark space.
