yep! it’s just less efficient than wired charging and whatever is lost in the process is turned into heat, which is particularly poor for your battery. batteries are consumables anyways and it seems like most people get it replaced at least once in a phones lifespan, so it doesn’t really matter if you’re ok with that. from my experience fixing phones over the years I can definitely confirm that using wireless charging consistently, particularly if you’re doing anything intensive at the same time, will lower the lifespan of your battery significantly.
other factors like usage time, intensity of use, and charging habits also have effects on the lifespan, so it’s hard to compare one person’s experience to a single other persons and draw a conclusion that’s anything other than anecdotal without some very specific controls.
what i do know for certain is that the heat generation from wireless charging has been long studied, and so has the effect of those heats on li ion batteries.
yes! heat is kinda the worst thing you can do to a battery. I’m not a chemist, but I believe the chemical reaction that charges/discharges a lithium ion begins to breaks down when performed in a heated environment, and I can confirm that consistent exposure to heat is how you get the really puffy spicy pillow batteries.
This is why I try to use my wireless charger when I don’t need fast charging, reduces the strain on my charging cable and the USB C port
increases strain on your battery tho
How is it worse on the battery than wired chargers? I’m guessing heat?

I have exclusively charged my phones wirelessly for about a decade. My batteries typically end up healthier than my wife’s over a long period of time.

I don’t doubt there’s a difference, I just don’t think it’s noticeable.
How, from the heat?
