Only reason I ever used a pad for my cell phone is to reduce wear and tear on the USB charging connector on the phone.

You'll be throwing that phone away, way before the charger and phone's appeal dies.
But you'll sure reduce battery's life from having it hot while charging wirelessly.

Yeah. I haven't had a USB connector failure on a cell phone in ages, even after several years of use each.

Now I don't think temperature is higher when charging wirelessly. I haven't noticed that, and I can't really see a reason either as long as both the charging pad and the receiving end in the phone are designed decently. And, as the charging current through wireless charging is usually much lower than when using a cable, the battery actually doesn't heat up as much while charging.

Berni:
I have a Samsung Galaxy J7 phone from 2016 and it was charged overnight for most of its life. The battery can still last over a whole weekend no problems. And even if it does fail the battery is user replaceable by simply taking off the clipped on back cover. Tho id more likely get a new phone instead to avoid the Android version getting too old to run most apps(This is the ultimate death timer for all smartphones, even if the hardware holds up).

Wireless charging should not be a problem as long as you don't try to get really fast charge rates out of it.

As for USB ports breaking. I have never broken one myself, but have had to replace a lot of USB ports in phones/tables for other people. Ranges from connectors that don't make connection anymore, to ones where the internals are a mangled mess to ones that are ripped completely off the board. You might take care of your connectors, most people don't.
