@cjschmedt your average Android device will definitely be slower than your average iOS device, unfortunately because the Android device is relatively underpowered. However we regularly ship performance improvements for Android, so we expect this issue to be alleviated for all but the lowest-end phones at some point.
A couple questions:
- How many items are you rendering in your collection? Have you tried using server-side pagination?
- What kind of collection are you using, a regular Card/List Collection or a Custom Collection? If Custom, can you share the structure of the repeated child components?
