Summary
(AI)
Apple announced the iPhone Duo at its September event. Hands-on time in the days after revealed more details.
iOS 27.1 shows battery health for each of the two cells separately. A blogger found a “Shift Left Edge” display setting, which MacRumors says seems meant for bulky third-party cases. Marques Brownlee found the vertical Dock holds only four apps when he could not add a fifth.
Apple has not explained the four-app limit or the reason for the bezel setting.
