I use wireless charging on my Pixel 6 very night, and was using it on my Pixel 4 before that. with the newer Android OS, they have adaptive charging when charging overnight. So it charges at a reduced wattage with the goal of having battery topped off about 1 hour before the set alarm, or whatever you have set as your bedtime schedule. Mine starts at 10:30pm, so anytime the phone is placed on charger after 10:30, the adaptive charging starts. I don't have an alarm set for weekends so my bedtime schedule ends at 7am.RE: Wireless charging
My first experience with wireless charging was maybe 8+ years ago when it first came out. It killed the battery on my phone in less than a year because of the heat it generates on the phone. This was when phone manufacturers started sealing the phones and you can't buy and replace batteries. I haven't used wireless charging since then, even if my phone has it. I don't know how far the tech has advanced since then.
Can't speak for IOS
