The 16 plus also got one hour more even if it did get less battery size. The a18 is just incredibly efficient for apple to improve the battery life by 4 hours on the pro. But it kind of sucks the smaller pro now matches the 16 plus battery life.
But what about battery longevity? Every year the degradation seems to increase much faster. My launch day 15 Pro Max now has 89% max capacity…. Meanwhile my 14, 13 and 12 Pro Max that I still use regularly are hovering around 85-90%.
That's not true for all, while your experience has been that, mine has been different.
I've owned a 15PM since release and I am currently down to 99% since I only charge it with the work PC or my personal Mac.
Battery degradation will depend on your usage and especially how you charge your phone.
