88% XS Max (Launch Day)

I charge whenever TBH. Just today I’ve been on 2% charged until 18% and then ran it down and partially charged to 70% using a Fast Charger.
 
My launch day XS Max is 92%. I found your result to be a bit strange; I charge by phone predominantly using wireless charger, and I have not faced any issue with the same. That being said, there could be issues with your battery, and you could reach out to Apple for a replacement. But, that's a long shot! A battery change might do the trick. Please do update on how things go.
 
Checked the battery health on my launch day XS Max the other day and it was 95%. Just checked it again now and it’s suddenly dropped to 89%? Battery life has been horrendous today too, though it’s been a hot day.

Edit: only charge once per day overnight with the charger that came in the box.
 
Thanks all. With things closed I’ll wait for a battery replacement attempt. I’m out walking into a mall to get to the closest Apple Store!
