Hi there! I know this is something googleable and sometimes comparable in GSM Arena. But i personally love personal opinions especially by people than databases (since there are experience and opinions). Im not a whizkid or a techy and not good with phones. So what are some differences with them?

And do battry capacity really makes a difference or is the pro max's larger just to cater more power especially for larger screen? (Similar to Google pixel 1 from 2016/2017 and same with vans with different body sizes that has different sized engines [like 2L for short wheel base while 5L for heavier superlong wheel base counterparts of the same lineup] just to balance things up)?

Also your thoughts on me (iPhone XS) moving to 11 pro/pro max (because 12 and present (15) have unique problems like radiation and camera/screen problem, these are my reason for my next buy to be 11 series). I care about reliability than flexing.

Thanks! once again I'm not good with phones and techs.
