It's not more convenient. It doesn't matter whether you have a cable running to your desk or whatever to be plugged into the phone or to have placed a charging pad there. The clutter is the same unless you use a lamp or table with a built in charging pad. Plugging in a phone takes 2 secs, about the same as placing the phone correctly on the pad. IMHO wireless charging is just a way to squeeze now money for useless stuff out of the customers. Don't forget that wireless charging is also less efficient. It takes longer, wastes more energy, requires more materials to be used in the phone and the pad and thus crates more waste at the end of it's life, so from an environmental POV you should avoid it.
P.S.: I used to charge my previous phone wirelessly, I'm back to wired charging with my current one for above reasons.
