My argument is very simple and you’re too thick to get it. Having more options is alway better, having a 3.5mm jack has literally no downsides. There’s no excuse to defend its exclusion. If you can’t understand that, then I have nothing else to say. If you like to get fucked over, you do you man.
The battery increase goes from negligible to null. There’s even a video from the StrangeParts channel where the guy adds the headphone jack to an iphone without having to remove anything at all. You drank the kool-aid my friend.
