I bought my iPhone 15 Pro in May 2024, and my battery health has already dropped to 89% with only 421 cycles. This seems early for such a drop. I’d like to check if this is normal?

Original Title: iPhone 15 Pro Battery Health Concern
iPhone 15 Pro, iOS 18
Battery health is affected by many factors - and does not necessarily change in a linear manner. As a rough approximation, you might anticipate losing 1% for each 50 full recharge cycles. You should note that your indicated battery health is expressed as a rounded-down integer.
As such, your iPhone's current battery health differs by only 1-2% from what might be anticipated on the basis of battery charge cycles alone.
Is 89% battery health normal for iPhone 15 Pro?
