iOS beta 12.1.3 3 and iOS 12.1.2 appear today in a comparison that shows us what kind of performance the two versions of the operating system offer for the iPhone, iPad, and iPod Touch. As you can see in the video clips below, the performances offered by iOS 12.1.3 beta 3 and iOS iOS 12.1.2 on iPhone, iPad, and iPod Touch are almost identical in all respects.
iOS 12.1.3 beta 3 works just as well as iOS 12.1.2 in just about anything you do on your iDevices, and that's very good news, because Apple hasn't made the situation worse. In theory, an iPhone 5S should work just as well with iOS 12.1.3 beta 3 as it does with iOS 12.1.2, so if you've been happy with the performance so far, that won't change.
iOS 12.1.3 beta 3 can currently be installed on any iPhone, iPad, and iPod Touch only by those who are part of the beta testing program of the operating system.
