Scroll delay on iPad

I’m seeing a delay of around half a second when starting a scroll on an iPad. When trying the same scroll gesture on iPhone and Android, the scroll starts immediately and is very smooth.

<ion-content class="has-header">
  <div class="blah-picker">
    <div class="results">
          <ion-col col-12 col-md-6 *ngFor="let blahItem of blahList">
              <ion-item class="item item-block item-ios" tappable (click)="selected(blahItem)">  


I’m using Ionic 3.4.0 and Cordova 7.0.1:

$ ionic info

global packages:

    @ionic/cli-utils : 1.4.0
    Cordova CLI      : 7.0.1 
    Ionic CLI        : 3.4.0

local packages:

    @ionic/app-scripts              : 1.3.7
    @ionic/cli-plugin-cordova       : 1.4.0
    @ionic/cli-plugin-ionic-angular : 1.3.1
    Cordova Platforms               : android 6.2.3 ios 4.4.0
    Ionic Framework                 : ionic-angular 3.4.0


    Node       : v6.10.0
    OS         : OS X El Capitan
    Xcode      : Xcode 8.2.1 Build version 8C1002 
    ios-deploy : 1.9.1 
    ios-sim    : 5.0.13 
    npm        : 3.10.10

is not really very specific. Please provide more information like exact model, year, OS version etc.

The problem appears on 2 iPads:

  • iPad Mini late 2012 model A1432, OS 9.3.5 (Model MD528C/A)
  • iPad 2 2011 model A1395, OS 9.3.5 (Model MC769C/A)

We have the same issue with the mentioned iPad. Looks like the pointer events are very slow.

I’ve checked the profiling via safari and it takes so long to detect touch start.

I’m facing same issue…
In below device

  • iPad 2 2011 model MD328LL/A, OS 9.3.5.

Please help me.

If you have large list of records try using Infinite Scroll or Virtual Scroll.
