So my 6S+ crapped out on Saturday. All attempts to reboot and restore it failed, with errors 4005 and 4014 being displayed. Have sent it to an authorised repair store to get it fixed, and have gone back to my older 5s in the meanwhile. Couldn't qualify for the express mail-in replacement option as I didn't sign up for Applecare+ either. I must say, while you can definitely feel the speed / performance difference on the 5s (everything seems to run that few seconds slower compared to the 6S+), I find I quite like the compact 4" size of the 5s. It's also way lighter, and I barely feel in it my pants pocket. Being able to pull down the notification shade with one hand is great, and it's clear that iOS has always been more optimised for a smaller, more cramped interface. Some of the apps I use actually look better, because they have not yet been updated for the larger iPhones. The irony. Only thing I don't miss is having to peck on the small keyboard. My typing error rate has definitely increased. The share sheet layout sucks too, with each share icon appearing more spaced out than it should. Battery life isn't stellar, but it has been close to 3 years already. Touch ID error rate also seems higher than before. If not for iOS 10 utilising Force Touch for a lot of its functionality, I am almost tempted to switch to an iPhone SE. Almost.
