How long has it been since the phone was new? On average an iPhone (actually, any smartphone) will lose about 1% of its capacity a month, however, the reporting isn’t always linear. And the difference could be that the health reporting is more accurate in iOS 16. But 96% is a reasonable value if the phone is 4 months or more old.

How old is your iPhone? Sometimes the drop is not linear and it will not drop for a long time (for example I have my iPhone 13 since June and still 100% battery health) but I know, that when it starts to drop, it will look like that it drops really quickly, but that';s not, it is just non linear dropping
