My iPhone 6S+ is still running super smooth. Maybe because I'm not a huge photography buff or mobile gamer, but each year I wait to see something that will finally make me buy a new one, but each year I just don't see it. I don't know exactly what I'm waiting for, but this wasn't really it. (Also enjoying using one of the last TouchID iPhones during Covid 19)
This is pretty much my exact situation. The new iPhones have been so underwhelming and so highly priced that I haven't felt the need or want to upgrade. Now previously this year, I dropped my phone and the glass broke - but it still works. So I am on the verge of upgrading, but iPhone 12 still doesn't really... make me want to upgrade - if I can put it like that. So I am rolling with a cracked screen iPhone 6S+ until…
I recently fixed a iPhone 6S+ for a friend, primarily with an aim to retrieve the photos and contacts. It wouldn't switch on, and had a broken screen. I ended up replacing the screen, battery and the charger port+headphone jack flex. It cost less than £40 in parts and some elbow grease; a superb compromise for a phone, which supports iOS 14 albeit it might not receive any future OS updates.
