I looked in "mail" and do not see the word "exchange"

l'd have to look at the actual account settings for each of your emails. you aren't going to go into the basic mail settings and see it there.

assuming you looked in the actual account settings and didn't see exchange then you don't have any. they are actually quite rare these days
 
I’m also experiencing high battery drain on a new (2 week old) XS Max. My last iPhone was a 6s+ and ventured to android after that. If I remember correct when the 6s+ was full charged it would hover at 100% for around 30/40 minutes before dropping to 99%..With the Xs Max I am getting to 99% from a full charge in approx 15-20 minutes with casual browsing.

I haven’t yet measured Screen on time for full cycle but I honestly feel it’s not even close to previous iOS or actual models. The drain is pretty consistent when it starts dropping from 99%
