I have an iCopy myself, but haven't really made use of it yet. In the process of familiarizing myself with it, I've gone through a few YouTube videos and tutorials and ran across one that I think will be of interest to you.
Basically, it shows the process of replacing a battery on an iPhone XR. The main focus of the video is showing how to get rid of the "genuine battery" warning, but part of the process it shows is reprogramming the battery health to 100% and the cycle count down to zero.
Now, it's my understanding that the batteries for iPhones X, XS, and XR can all be reprogrammed. The X does NOT have the genuine battery warning; that started with the XS. Apparently, starting with the 11, Apple began encrypting the cycle count and health percentage, meaning it could no longer be reprogrammed. Aftermarket manufacturers have come up with a little converter/adapter board that plugs in between the battery and the motherboard and allows the stats to be reprogrammed.
Here's the video I was referring to.
iPhone XR Battery Replacement - No Error Warning, 100% Life, 0 Cycles
Since your X doesn't have the genuine battery warning, you don't need to change the BMS. However, at about the 4:00 minute mark, you'll see where they plug the battery into the iCopy and the iCopy into a computer that's running the Qian Li software. Using the software, they show you how to reset the cycle count and health percentage and write back out to the battery.
As I mentioned, this is on an iPhone XR, but I don't see any reason why it wouldn't work the same on a X.
This is all based on my current understanding of how the iPhone batteries work now and I could be wrong, but I think all you have to do is plug the battery in with the iCopy connected to a computer running the Qian Li software and you should be able to set those numbers to whatever you want.
The part that actually puzzles me is wondering why a brand new battery would be coming up with a health value of less than 100%. That should be the baseline where it starts. so I don't understand why you're having to reprogram it in the first place. What does the cycle count show?
Anyway, I'd love to hear whether that works or not since, as I said, I have an iCopy too and want to know how to use it.
Updated to reflect that battery encryption started with the 11, not the 12, so 11, 12 and 13 all require tag-on boards to be able to modify the battery health information. That can be done with either the Qian Li iCopy or the Copy Power programmer. I have not seen any support for the iPhone 14 as of yet.
did you switch over the bms board, i dont think icopy can reset battery capacity
@tech_ni All i did was install a new battery with icopy. Is there no solution for this?

@willie604 could depend on the ios, i know newer models need the bms board from the original battery transferred to a new battery cell and programmed in some cases using a tag on flex
Hey, Ive confirmed with the phone owner that he has os 16.3.1.
I still have his old battery as well.
So would transferring the battery circuit help achieve resetting the calibration?
What do other people do. Or tell there customers?
Thanks for your help

@willie604 probably wouldnt help as you need a certain program to reset health and cycle count
