All our modern charging methods are really bad for batteries. Wireless is inductive which means the charging voltage is noisy and very variable, this means heat and that stresses the batteries faster. But, wired charging with PD uses really high voltages, which are sometimes way too fast. Also stressing the battery. We’ll see what comes of it but the recent couple of phone generations are prone to be the ones with the worse battery life expectancy.

Companies are usually aiming for 80% at two years time. That means that a phone that barely survives a day when new, will not make it through the day two years after. As the battery loses capacity, it requires more charges per day, accelerating the degradation.

Here’s iFixit assessment of wireless charging.

This is MKHB on why heat hurts batteries and how companies try to fight back the damage of fast charging.
