Downgrading iPhone 15 from iOS 27 to iOS 18 due to battery and keyboard issues
I love the new features of iOS 27 but my battery life does not last long and the keyboard does not work properly. I had none of these issues with iOS 18, thus I would like to change the software on my iPhone 15 back to iOS 18. Please may you advise how I go about doing this.
