Battery health

As I said in my earlier response, use the Contact Support link at the top of the page here, or you can use the Apple Support app you can download to the iPhone, or they have a Twitter for support, @AppleSupport.

Battery health is an estimation. Unless your iPhone battery is down to 80% before a year is up, you have nothing to worry about. The battery health percentage will fluctuate as you use the device. Nothing to worry about.

I'm telling you it is not an issue, however if you feel it is something that you need Apple to address, you are welcome to use the Contact Support link at the top of the page here. It has nothing to do with the new update, that is for sure. I will tell you that Apple is going to tell you the same thing that I said in my original post and that is unless it is down to 80% by the end of a year, it is not an issue.
