Mine went from 100% to 95% in last 6 weeks after being at 100% since release.On July 14 Battery Health was 99% and today, July 26, is 98% I was not expecting that Battery Health would decrease from 100% to 98% within the same month.
90%? That seems wasteful.I got mine on release and it's on 95% now.
I am a heavy user (8-10 hours screen time daily) and every day I use most of my battery.
I'm not really worried, I'll simply have Apple replace it when I hot around 90%.
