Freezing apps, touch not responding, stuttering safari since iOS 12 update on air 2

[Audit13]

Ever since I updated my air 2 with the latest iOS 12 release, I find that my iPad is not as responsive to touches on the screen as it used to be, typing is really slow, scrolling in safari stutters, safari will render half a page with the bottom of the page being blank, and apps will freeze.

I have reset the iPad to factory settings and started using safari without signing into iCloud or installing any apps. Within a few minutes, safari starts to lag again.

The hardware buttons are working, charging is not a problem, battery health is at 96%, no cracks on the screen, iPad has never been dropped.

Any ideas as to what I can do?

Same problem here (iPad Pro 2017)

As I type this repy, the keyboard is really lagging, so much so that I could finish typing four words before they appear in the reply box.

How did you reset back to factory?

Two ways: through the reset option in iOS settings and through iTunes.

Same problem with last years iPad Pro. Especially in Safari.

Same thing will sometimes happen with my iPhone 6s on the latest iOS but it's not as bad as it is with my Air 2.
