iPhone 12 Pro Max IOS 15 worse on battery than iOS 14

[nph]

I got 2 days with my iPhone 12 Pro Max after I disabled findmy function.after upgrading to 15 I am now back to best case 1.5 days and more often we then not just one day. Turning off 5g for sure also helped.
Is it just me observing this? Is there any other setting to disable in 15 to get back my great battery life?

I'm seeing my battery drain throughout the day even without use much more than with iOS 14. On an iPhone 12 Pro. Not sure what's driving it. Would love to see some tips to help with this.
