iPhone 15 Pro Max Battery Healh

Yes, that's absolutely normal, bearing in mind that that is an "approximate" value (it might be = 99.9), related to when the battery (not the iPhone) was new.

same issue with me, I strongly don't think it's normal if you compare it to the previous iphone models.

My iPhone 13 pro max and 14 pro max had 100% battery health for up to 11 months. This is unacceptable. Has Apple produced a newer inferior set of batteries for the iPhone 15? If so this is super disappointing after paying so much for a pro model phone upgrade.

According to apple’s official reply it is normal. But according to our past experience with iPhone 13 and 14 pro max it is not normal. Nor should it be acceptable. We paid premium price for this device. It shouldn’t be preforming worse than previous models.

My pleasure

Same experience. I am very unhappy that my new 15PM has declined to 99% of less than 2 months comparing to my 14PM that lasted 7-8 months before the battery health declined to 98-97%

That is not ABSOLUTELY norma!!
