14 Pro Max at 88%. I’ve never had battery health degrade this quickly on previous iPhones, and I’ve had every iPhone since the 6. I don’t recall percentages on my XS and earlier, but I know that my 11 Pro Max was at 99% when I got my 12 Pro Max, and it was at 98% when I got my 13 Pro Max. My 13 Pro Max was at 93%, when I got my 14 Pro Max, and the only thing that’s been different in terms of my charging behaviors is that I’ve used MagSafe charging much more. Maybe the heat wireless charging creates is worse on batteries, but I’ve read others using MagSafe not have this problem, so I really don’t know unless Apple has tweaked the way they report battery health.
EDIT: Now I’m at 86%. It’s dropped 2% in a little over 2 weeks.
It’s not just wireless charging causing excessive heat on this gen.
I had to stop using wireless charging in my car (and subsequently everywhere) because the phone overheated. Then it started throwing overheating errors while charging plugged in.
Maybe these batteries are taking a thermal beating.
Checking in with an iPhone 14 Pro at 96% since release, which doesn’t sound bad but is markedly worse than the last several iPhones I’ve had.
Exactly like mine. 96% since release. I’m using AOD and 99% wireless charging.
It’s ok, never had any issues with my battery life that I ran out of energy.
We probably have to accept, that these battery’s are performing at their very limit and have no thermal system to keep them in a specific temperature range.
My iPhone X was about the same. In installed a new battery when it was 2.5 years old and I used it for 5 years. I will probably do the same with my 14 Pro.
