Apple's forthcoming iPhone refresh — presumably an ‘iPhone 6s’ and ‘iPhone 6s Plus’ — is set for a major upgrade in the camera department as Apple has reportedly relented and decided to join the megapixel race with a twelve-megapixel iSight camera on the back of the new phone(s).
But the megapixels don't tell the whole story.
According to Kevin Wang, IHS's Technology Research Director for China, the pixel size will be smaller, raising questions about the camera' performance in low-light conditions.
