How come? I thought its one of the favorites there as I saw here a few months ago https://www.macrumors.com/2017/05/23/iphone-se-tops-customer-satisfaction-survey-despite-shift-towards-larger-screens/
From my personal experience, it looks great but its quite a lot harder to use, with the status bar all the way to the top. The GS8 is almost has hard to use as the older Note series.
Not true, Android phones with a similar hardware configuration consistently use 20-50% more power consumption than its iPhone/WP counterparts. The saving grace is that Android phones generally have 20-50% larger battery to compensate that.
Your Xperia is one of the best examples:
Despite having almost twice as much battery capacity, the Xperia is beaten by 15-40% by the iPhone SE in realistic scenarios. To make matters worse, all that is completed with a battery thats nearly half as large.

Another example? Identical hardware, different OS
