[AC Question]

I just bought a couple of wireless chargers and am concerned that they will reduce the usefull life of my phone.

Wireless charging isn't hard in your battery... From the battery's perspective, it's getting charged and doesn't care how that happens really.

Now, if the wireless charger ends up generating way too much heat, that's another issue. But it shouldn't do that in the first place.

Feel the charging plate after about 30 minute of charging. If it's more than warm, it's probably raising the battery temperature. How much? There are apps that will tell you. Run the app, put the phone on the charger and see how much it heats up (compared to charging it with the regular charger). A few degrees more is okay - 20 degrees isn't, and I'd return the charger.
