Also, my phone charges slower with a wireless charger.
Lots of hand wavy theories and generalizations in the answers below, some of them sound very convincing. None of them actually cite any sources or backup those theories with data.
Here’s my own acedotal experience. I’ve put my phone down on a seemingly well designed wireless charging pad every night for almost 4 years and this phones battery has shown zero sign of deterioration that I can see. This is the first phone I’ve ever owned with wireless charging and also the first with a battery that hasn’t given up the ghost in 2 years or less. The same pad also charges my smart watch every night, which doesn’t even have any other option for charging.
Next they’ll be telling you to avoid using cruise control on the highway because it will wear out the transmission. Use your phone as it was designed to be used and stop worrying.
The problem is heat, not charging speed. A wired charger heats the phone less than a wireless charger, and a slow charger heats it less than a fast one.
It’s not like wireless charging will literally destroy your battery instantly, but it WILL do so faster than wired charging at the same speed.
You could offset the heat by charging even slower via wireless (easy with something that has a small battery to begin with, like a watch) but no matter what method is used, the one that runs the battery the coolest WILL last the longest, whether the difference is just one year out five, more, or less.
Wireless charging WILL wear out your battery faster.
For longevity, use a slow wired charger. This will put the least thermal strain on the battery.
