Not going to lie but the iPhone hands down is a pain in the ass. Battery life is shite compared to the China phone, the thing constantly goes to emergency menus in my pocket or tries to tap pay for shit.
Reception on it is AVG at best (both phones on same network) and it's general usability sucks. Like can't even just plug it in to transfer files, the fingerprint sensor has about 1/3rd the hit rate of my China phone, the thing can't shoot video while in a phone call, hell I can't use my earbuds for hands-free while it's on the charge because it has no headphone jack (oh and the stock headphones are about the tinniest worse quality sound I've had in half a decade). Christ I could rant for dayz but you get the point the list goes on.
Tbh all these things suprise me, I've avoided iPhones like the plague for moral reasons but I figured/assumed the phones would have decent usability. Apparently I was wrong as I have been forced to discover thanks to work.
I would have to agree with the article, shit that is simple and fairly easy to do elsewhere becomes a tedious task W/ iPhones.
