Now, as a fellow user my first suggestion is to try and resolve the battery issue. If you have not done so already, please do a forced restart. A forced restart does much more than just turning your iphone off and back on. If you’re not familiar with the procedure please follow the step by step instructions in the support article i shared below. Battery performance should come back to normal in a day or two.

It’s not possible to rollback an upgrade. It is not possible to go back to iOS 17.x.x.
Now, time for a confession. I’m no Freeform user and in fact I’d never opened it before. But I am on iOS 18.1.1 and it seems to be OK. Here’s my screen shot.
But to my inexperienced eye, mine seems different. Now your turn to educate me. What is that yellow line coming down the right side? Do you have some kind of border or guide activated in your app? Look in the More Button (3 dots in a circle) and see what settings you can change to fix the border/right side issue.
What exactly doesn’t work with the keyboard?
