Incorrect. You cannot downgrade to any iOS in general.

I am the polar opposite. I had the same battery draining issue since I updated my 14 pro to IOS 18, if I left the phone uncharged before sleep, it would drain from 90% all the way to 40% in the morning. The 18.4 actually fixed the draining issue for me. I would recommend backing up your data and do a fresh reset on your iphone.

I will add on and say that in most cases when a new iOS update is released, the older version stops getting signed pretty quickly. In part this is to prevent unauthorized modifications to downgrade.

Yes, I was also experiencing this, and so are about all other users that update. In fact, this phenomenon is normal and expected when you update your iPhone. The reason being is that after you update your iPhone, it must work extra hard to sort and move all your data to the right places. The iPhone also needs more energy to be able to introduce and use different features or functions incorporated with the update. This can all cause an increased battery drain.

This phenomenon is not permanent and usually after a few days to a week, your iPhone’s conditions will return to normal. And no, you cannot downgrade your iPhone’s iOS.

I have an iPhone 11 and the battery seems to be decent on iOS 18.4

Hello ~ Agreed and excellent information.
