i am really unsure on the ios26 it has completely and utterly drained my battery 3x worse than it was before

In the first 48 hours or so after a major update, your phone is doing a lot of background indexing and housekeeping. The battery will drain more quickly and it will get warmer. This is normal. It should settle down soon.


i hate the design of it and i hate that my keyboard has changed

You should let Apple know your thoughts here:

It is not possible to go back to iOS 18. I don't know what you mean when you say, "my iPhone is not fully set up properly."
