OS 12 Problems and How to Fix Them: The latest version of iOS 12 is causing issues for some iPhone, iPad, and iPod touch users. Some of these issues are new, while others have carried over from previous versions of iOS.

The current list of iOS 12 issues includes strange battery drain, Wi-Fi issues, Bluetooth issues, Touch ID issues, audio issues, and more.

While some of these issues may require a solution from Apple or a visit to an Apple Store, others can be resolved from the comfort of your chair or couch.

If you’re using an iPhone 6s or newer and for some reason are still on iOS 12, consider upgrading to Apple’s iOS 14 update. That might have helped.

In this guide, we’ll walk you through the fixes for the most common iOS 12 issues. If you’re dealing with battery drain, connection issues, or something completely different, take a look at our list before contacting customer support or taking your device to the store.
