Are you asking what, if anything, would/could you lose if you update from iOS 9 to iOS 10?are we losing a lot on IOS9?
i don t have Idevices with IOS10 so i don t know what i m losing.
If you are using an app on the device itself to look at battery health, then the information that is displayed as of iOS 10 isn't all that accurate. You'd basically want to use a computer application, like Coconut Battery on the Mac.I updated to iOS 10.3.1 from 9.3.5 just a day ago and battery health is already down to 89 % on my iPad mini 4 whereas it was 97 - 98 % just 2 days ago on iOS 9.3.5 I'm not sure what caused such quick degradation...
Also app doesn't show charge cycles anymore, but I was warned about it here...
