My iPhone battery health is degraded to 90% of its original capacity withing 10 months of usage, is it normal or something to be concerned about?
I usually charge my iPhone one time per day between 20-95%.
iPhone 14 Pro Max, iOS 17
Yes, it's perfectly normal.
Batteries degrade over time with usage due to chemical aging, that's just how they work.
You can expect about a 1% drop per month with average use on an iPhone. This is an approximation, that is why it may be plus or minus a few percent on a month to month basis.
Apple recommends replacing it when it reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.

If it was showing 90% after 20 months, then there was something wrong with the battery sensor. 1-2% a month is the norm.
My iPhone 14 Pro Max has 91% after 13 months of use. I charge it once a day.
The answer has already been given, there is nothing wrong with your phone.
Thanks for the info, but in my previous experience with iPhone XS plus and 11 pro max this one is degrading way fast, my iPhone 11 pro max battery had got degraded to 90% in almost 20 months
Your iPhone 11 did a whole lot better than mine......and I am a very light user.
