Amazing that they couldn’t get this to market. I’m not a big fan of wireless charging I feel like it’s the biggest reason for my device batteries degrading. On my iPhone 15 I’m purely using a cable for charging and it’s still 100%.
I can't remember the last time I've plugged in my iPhone 12 Pro Max. I charge it on a Qi mat at night and on a MagSafe stand for most of the day at my desk. It's almost 4 years old and 76% battery health. Your iPhone 15 is like 7 months old.
