Question for you ... just this week I upgraded to an iPhone 15 (from an iPhone SE 2020). When I spoke with an Apple Support rep, I asked about using the original 5W charger from that other phone. They recommended only using the Apple 20W charger because supposedly lower watt chargers can cause batteries to get hotter than normal (I purchased a 20 watt charger so already have it).I decided not to use magsafe and have been charging wired on a low watt charger... since I charge overnight and don't really need fast charging. I guess that experiment bought me an extra 45 cycles lol.
I also have a 20W fast charger (multi port fast charger) so am wondering what is really the best wattage to use when charging. Sometimes I connect it to my Mac but want to implement recommended charging since it's new.
