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%.
 
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.
Mine went from 100% to 95% in last 6 weeks after being at 100% since release.

I don't think the Battery Capacity percentage is very correct, it's more of an estimate.
 
Mine always go down quickly although my 12 pro max lasted a few months longer than my 11 pro max. At 16 months my 11 pro max was at 88% and at 18 months my 12 pro max was at 88 %. Once they get around there that’s when I have to upgrade.
 
My lunch day 13 Pro Max with 110 charge cycles, still hovering above 102%. I don't use MagSafe charging, I stick to using a 12 watt charger. And I don't use optimized battery charging either. Everyone has their own favorite way to charge.
 
I know that battery is important to a lot of people but doesn’t it seem wasteful to have the battery replaced when it’s still viable. Especially the 13PM. 90% of its battery is still way more than my iPhone SE (which can get me through a day just fine). Once removed the battery can’t be reused can it?
 
Launch day 13 Pro is at 91% already....have NEVER had an iPhone battery degrade this fast before....Apple will not replace battery until it gets to 80% or lower...
