14 pro max Battery Drain Fast After Update

Apple does not support downgrading your iOS. But I do have an answer for you that will explain this phenomenon. After an update on your iPhone, it must carry out several background tasks in which you can experience an increased battery drain. This should only last a few days until it is back to normal.

Sorry, it is not possible to downgrade the iOS on an iPhone.

It should be, depending on the amount of data you have. As your iPhone needs to index it all and sort onto the new software.
