Apart from the camera/battery life I’m not really sure of what they could do hardware wise to improve the phone. The phone works amazingly well at the moment and excels in everything it does.As much as I appreciate upgrading to an iPhone every year, I have become quite numb to all the features, although I do really appreciate the camera, as it does take amazing quality photos. But I do await the day where the Apple Watch _could_ possibly replace the iPhone, if it ever supersedes that point.
i wouldn't mind having a double sim slot, 5g, better battery, maybe a phone that folds?
How about put light into the Apple LogoRelease the smart battery case for the Max and I’ll be good for a few years.
As far as upgrades go:
-ceramic frame
-Fingerprint in that unused / useless Apple logo
-significantly better battery life
-higher resolution screen
