You may not expect desktop-class performance, though others do. Display scrolling on a mobile handset is an indicator of quality that separates cheap devices from those that one might actually want to use to get work (or play) done.

The thing is that the display scrolls without any hiccups on this device. Pulling down the notification shade is always fluent, gestures work without hiccups, controls appear and disappear fluently. The UI is not where these devices tend to show their lack of performance, for that you need to open a browser and load some heavily javascript-encumbered sites. As an example I use OpenHAB with some embedded (live) Grafana charts for control and data visualisation. Opening the site or the app (which just embeds the site) on my device takes a second, on my wife's S23FE it appears a lot faster. Changing between pages on the site or app is also a lot faster on her device than on mine. Since I program the thing I like using a somewhat slower - but still perfectly useable - device as it makes sure anything I produce will be fast enough even on less than top of the line hardware. I follow the same creed when it comes to PC hardware by using older devices, it has always served me well.

Understood, though consuming the sausage (as an end user) is often a very different exercise than making it, so to speak. Battery tradeoffs are a real consideration for end consumers, though are not as much an issue within a development environment where the test device is tethered to the host development machine.

To each, one's own.

Those are cheap devices.
