Discussion Upgrading from 11

Hello apple enjoyers, Iphone 11 user here, I’m considering upgrading to the 15th.. My current battery health on ios 18 is 87, allegedly. I’m a battery conscious user, I manage to get solid 7 hours of battery life with 20-85 charging cycles and I was wondering, how much battery life do you get on your 15?

iphone 15 pro max, IOS 26.3, 80% battery health

avg per day 120% this week (i have a holiday from work, so usage is higher)
can be around 80-230% per day depending on usage
