Yes after every Software Update, there are background processes being performed to index files and that will continue for about 4 days. Not only does this effect Battery usage, but will also make your device feel warmer and there will be some UI lag while this indexing continues in the background.
Apple details what you should expect after a Software Update and that usually happens after you initially set up your phone.

Ah, that’s normal for the first few days. You’re iPhone is syncing, indexing, backing up and optimizing data. Make sure you plug your iPhone in at night, connected to WiFi and locked. This allows a lot of background activity to occur when you’re not using your iPhone.

Sounds like you have an app in a loop utilizing 100% of your processors. When did you get your iPhone? Have you done a forced restart?

Absolutely not normal which is why I suggested the self discharge test. What were the results ?

It may probably be happening because of upgrade to iOS 27, give it a while it should become normal as the background changes are completed.
