I owned many Android phones over the years, beginning with the OG Droid. Had some Samsungs along the way, my last few were Pixels. My final Android phone was a Pixel 3, I switched to an iPhone SE 2020.
Maybe the total time to complete a given task is about the same, but I can seriously say I have never seen the iPhone drop a single frame. The Pixel got choppy all the time. Every Android phone owner knows the feeling of "why is my phone suddenly hot? Oh some runaway background service" or "why is this thing running at 5fps? Oh an app is auto-updating in the background".
iPhone just doesn't have these issues.
