My IP12 Pro Max (bought 01/2021) dropped to 99% after 9 months or so. Ever since then it has been degrading faster. Now, after two years it is on 89% and it still gets me through the day, no problem. I've been charging it mostly during nights via MagSafe with the Optimised charging turned on and when connected to CarPlay. Current battery issues are mostly related to iOS16, which has negative impact on many since its launch, so I would not care so much about the actual percentage of battery capacity right now, even when it drops faster then usual if it actually do not degrades directly the user experience.
Also I do have MacBook Pro M1 Pro about 4 months, charging it only when it drops to 20% and unplug it after it reaches 100% and the battery capacity shows now 98% after 40 cycles. However it holds the charge better then when I bought it with earlier version of Ventura. I have treated the battery on my first 17 MBP the same way and the original lasted for 6years and was still able to hold charge for approx 2-3h
