Man don’t pay attention to it. Battery degrades. It’s a fact of life. When it’s too much just change it. It’s not worth it to obsess about such a trivial thing. Charge your phone whenever you want and enjoy and use the phone. Done deal. I stopped looking at my battery health the first month. I’ll change the battery next year.It it normal to have 89% battery health . I bought the iPhone XS on Launch in 09/18
I am not a heavy user and charge before it hits 20% to full..
what’s you percentage like?
iPhone 7 here. 3 years old in around 2 months or so. 86% battery. Always charge to 100% over nite.
Would be interested to hear how low others have gotten before phone operations started to get noticibly worse.
