YMMV but I don't think Apple are going to do anything about it. I've been to the Apple store and spent countless hours on the phone to support asking them to investigate why my 4 month old iPhone 14 Plus' battery has degraded to 93% according to CCBattery/iMazing and 97% according to iOS after just 39 charge cycles, and was handed the usual '80% capacity after 500 cycles' and 'batteries degrade over time' spiel but they refused to offer a plausible explanation for why that would happen for a 'new' battery that was manufactured in Feb 2023, has done less than 40 charge cycles and isn't subjected to extreme temps at all.My launch day 14 Pro Max is at 86%. In the last couple of months I have really felt it decline.
Would apple warrant this, or is it just considered normal wear and tear?
