iOS 14.5.1 Update Making Some iPhones Slow and Laggy

Okay, so it wasn’t just us. After updating to iOS 14.5.1 released this week, a mere 133.1 MB in size, our iPhone 12 Pro Max has been slow and laggy at times, compared to iOS 14.5. A reboot of the device seems to have fixed the some of the lag for now.

Others on Apple’s online community forums and MacRumors forums are experiencing the same, noting lower Geekbench scores, suggesting some throttling may be a play here.

There doesn’t appear to be a fix in sight, but a reboot of your iPhone 12 Pro Max or other device may help fix the user interface and app lagging issues.

Others are noting iOS 14.5.1 also causes faster battery drain, plus Siri only works intermittently as well.

The video below from Zollotech shows a variety of different Geekbench scores with iOS 14.5.1 across his test devices.

Are you seeing any lag with iOS 14.5.1 installed? iOS 14.6 beta 2 is currently with developers and public beta testers–and it can’t come soon enough.
