Just a follow up from yesterday, I do notice that I get a slight headache every time I look at the phone. Hopefully I'm one of those that found they got used to the PWM (which is the only thing I can think of that gives me eye/head ache.
I told my wife that maybe it's for the best I have a phone that gives me a slight headache

lol, I'll use my phone less.
Battery today is 2hrs SOT, and sitting at 65% battery. Not bad! Better than the iPhone 7 which is all I wanted: a phone that'll get me through a solid full day and evening if needed without having to worry about charging.
not about this headache.... either I get used to it, or I return for what....... a big ol' 11???????? Or another battery worry with the SE? I'd rather take the headache and use the phone less, lol.
we'll see in another few days if I fee the same.
