Ionic 4 slow performance on user interaction

I was having really poor performance on my Android 9 device, what really improved the UX in my case was:

  • use of *ngIf to reduce the dom size as much as possible
  • improve image size/compression (with tinypng or similar)
  • disable ionic animations with IonicModule.forRoot({animated: false})

So the bottom line IMO is keep the dom as small as possible and avoid animations and/or big images.
