Apple’s latest operating system, iOS 26, introduced the much-hyped Liquid Glass interface, marking a major visual shift for iPhone users. While the design overhaul grabbed attention, the update has also triggered complaints of lags, glitches, overheating, and faster battery drain. As is often the case with early builds, the software appears to need refinements, leaving many users frustrated.

The good news is that Apple is still signing iOS 18.6.2, which means dissatisfied users have the option to roll back to this earlier, stable version. However, downgrading is not as straightforward as hitting a button—it is a technical process with risks. Importantly, the procedure wipes all existing data from the iPhone, making backups essential.

A report from WCCFtech highlights that this process “should only be attempted with care,” advising users to back up important files such as photos, notes, and recordings before starting.

How to Safely Downgrade from iOS 26 to iOS 18.6.2

  8. Restore or set up freshOnce installation is done, users can either restore from their backup or set up the device as new.

Apple’s Response

Apple maintains that updates are necessary for security, stability, and new features. The company notes that temporary issues such as overheating or reduced battery life are often caused by background processes like re-indexing and app updates following a major software release.

For those struggling with persistent iOS 26 glitches, however, reverting to iOS 18.6.2 offers a temporary solution until Apple rolls out a more polished update. That said, the downgrade process is best suited for users comfortable with technical steps.
