iPhone 15 pro battery health decline

Maximum Capacity will drop around 1% for every 25 cycles to meet Apple’s specification of staying above 80% for 500 cycles (do the math). So 98% is about right.

It's normal for the battery to lose about 1% a month.

He is using iPhone 15 Pro and for now iPhone 15 series apple has increased the battery count from 500 to 1000 cycles to retain 80% of their original capacity. So this maths is appropriate for iPhone 14 and lower models but i don’t think will be relevant for iPhone 15 models. I am attaching the screenshot below from the official Apple website for your reference

Mine is 2months 98% cc 60. Is it normal.?
