I'm using iPhone 15 since November 2023 after 6 month my battery health decreased to 99% which was normal as usual, after that my battery health is decreasing very fast and now on 25 August 2024, my battery health is 89% so there might be serious battery issues and apple not supporting me.

Does anyone have any solution??

It is normal— nothing to fix here. Just use it as you see fit.

≤ 80% "maximum capacity" is when Apple suggests the battery is eligible for replacement

There is no problem with your battery.

The phone is 10-11 months old and it is normal for Battery Health to decline on average over time at about 1% a month. So, you would expect that the battery is now at about 89-90%.

You can take the phone in to the Apple Store if you want, but you will be told that your battery is performing normally.......because it is.

IF.....the Battery Health had declined to less than 80% in the first year of operation, Apple would replace the battery for you.
