I had same problem with my iPhone 12 Pro Max after upgrading to iOS 15.1. After troubleshooting with online support and then at the genus bar, we decided to perform a device reset but kept the data on the device. Since then I’ve restored my phone’s normal battery life of practically a full days use like I had before. Hope that helps someone else facing this issue.

For what it's worth, I disabled background app refresh and I've seen a massive improvement to the battery. When I left the house this morning the battery was at 98%. Five and half hours later it's at 79%. Hope someone else finds this useful. If a few of us could try this and report back to see if they have also had an improvement. Of course, this isn't a solution or a workaround. Just an observation as to what service may be draining the battery.
