As can be seen in the c hart from Estimize in the December quarter last year Apple blew away EPS expectations. The high-end of EPS guidance was $2.54 and the company reported $3.16. However the year before that with the iPhone 5c & 5s Apple's revenue was a bit below the high-end of guidance and its EPS was below the high-end. While it did generate revenue and EPS within its guided ranges it does show that the off cycle iPhone refresh doesn't drive large upside.
