I‘m sticking with my iPhone 6. I like to listen to podcasts for falling asleep, while charging it. And simply connect it to my 20 year old Hifi system. I fail to see why using a y dongle for connecting a headphone plus the charging cable would make my life better. I like the form factor, too. I guess the only other choice would be an iphone SE. I once spend a few bucks on a new battery. Otherwise, it is a perfectly fine phone, used (too) many hours a day by me for years and it‘s still almost pristine. It just works. I don‘t see why one should throw it on a dumpster. If it was a bit faster and had a bit more memory it would be the perfect phone. But if they come with an upgrade, have a headphone jack would be the killer feature.
