Mine’s still 100% at 250 cycles.My 15 Pro Max battery dropped by another 1%. It is now at 86% battery health with 308 cycles.
I saw an IPhone X with 1200+ Cycles and was at 83% Battery and no warning or slowdown. If Apple really went back to a chinese junk battery (500 Cycles) with the much never IPhone 14 Pro?The good thing about the 15’s is the cycle count to 1000 and higher if your lucky for the battery to get to 80% ( this is arguably the greatest thing alongside USB-C and Smart HDR 5 amongst others that make even the non pro iPhone 15 more better than the 14 Pro)
So to the OP don’t be concerned 😊
Anyway I don’t have a 15 but I have the 16e and even the 16e gets the latest generation battery technology ( and that and the fact that A16 Bionic didn’t mix well with the battery’s in the 14 Pro’s compared to the 1000 cycle count) makes the 16e better than the 14 Pro when it comes to the health of your phone
Anyways I used 2 cycle counts on that iPhone but A16 Bionic can handle 1000 cycle counts on the 15 better than 500 cycle counts on the 14 Pro( and much less risk of the battery swelling compared to so many 14 Pro’s ( and I witnessed one too)
Also the beta releases seem to coincide with the battery health drops.Dropped again overnight. 😭View attachment 2488514
this is probably because each beta install/update re-calibrates the battery healthAlso the beta releases seem to coincide with the battery health drops
Since the % from 90 down to 81% drop slower you maybe reach 1K Cycles an be still over 80%View attachment 2488556
always capped at 80% with the rare top up to 100 when I'm going to be away from a power source

Update as of today. Pretty impressive that it's dropped 4% in just over a month!As of today, 93% with 232 cycles. I have been using it much heavier recently, so not very surprised by the drop.
Are you currently using iOS 18.4 Beta (developer/public?)?Update as of today. Pretty impressive that it's dropped 4% in just over a month!
Yep, I install the dev betas on day 1 most of the time.Are you currently using iOS 18.4 Beta (developer/public?)?
