iPhone 6 and 6s still make 21% of the pie chart. I wonder how many of these people are still holding on to the phone due to the headphone jack and the charger.
I hold onto my SE and 6s plus for that reason. I do own AirPods, and I like them... but they don't have quite enough battery life for a whole day worth of conference calls, audiobooks and podcasts. And they definitely cannot compete with standard headphones for music. A headphone jack easily accommodates any headset device I want to use, and I'm not willing to regress back to using an adapter dongle.
Same here. I have a good set of headphone that are not wireless. I use an SE at work as an iPod touch (hotspot with my 7). I like being able to charge the phone and still be able to listen to stuff on my headphones. I like my AirPods at the gym and gym only.
I'm a 6s+ holdout. That's among the reasons, but the real reason is that the phone still does everything I want it to do. There's just nothing remotely compelling about an Xs for me. I probably wouldn't bother upgrading for $100, certainly not for ~$1000.
Fingerprint scanner and charger.
I really don't want FaceID; and, since I have cables throughout my apartment, I don't want to have to buy 10 new cables :(
