As someone who constantly has to step away from my desk during the day, I don't have to think about charging the phone anymore. It automatically goes on the wireless stand (directly in front of me) when I'm back at my desk. I can be certain that if I choose to go out for the evening after work, I wouldn't have to worry about being stranded somewhere far from home because my phone died. (Side note: Uber and Lyft have really decimated the taxi industry, even for a downtown area in a medium-size city.)
If you can keep it from charging too high, it's all upside.
This is especially pronounced on phones, where batteries are already calibrated to have a high charge cutoff (ie battery longevity vs capacity compromise is heavily at the capacity end).
It's a thing for some laptops; e.g. Lenovo specifically advertises such a setting.
One advantage is that it does not destroy the USB port. Constant plugging and unplugging can really wear some ports after 1-2 years, depending on manufacturing quality. To the point that it won't charge anymore. (Hopefully will be less of an issue with USB-C which seems better designed than microUSB). Plus the convenience.
Newer wireless chargers also usually have some form of active heat management (i.e. fans), and anecdotally my phone only ever gets lukewarm to the touch, even with a somewhat bulky case on it.
At the end of the day though, I personally wouldn't mind having to upgrade my phone slightly faster than I would otherwise in order to enjoy the convenience offered by wireless charging, but definitely speaking from a position of privilege here.
I found about this option on a motorcycle forum where a specific helmet headset was quite sensible to breaking the micro USB charging port. I bought a couple of cables and several micro-SUB connectors, then I bought a handful of USB-C ones and a few more cables and now everything is by default using magnetic connections.
