The larger version of the iPhone, which will probably be called the iPhone 7 Plus if Apple sticks with its conventions, may have two cameras on the back of the phone.
Despite not being a "major" upgrade on the scale of years past, Apple is expected to make at least one big change: many reports have said that Apple will do away with its headphone jack. Instead, reports have said, the company is expected to use the space now occupied by the headphone jack for a second speaker.
Headphones for the iPhone may instead work with the Lightning port on the bottom of the phone, which is currently only used for charging and data transfer.
That would make the standard headphones that users have had for years completely useless with a new iPhone. Since the rumor first broke, there's been lots of pushback from those who say it's not a consumer-friendly move. That includes Apple co-founder Steve Wozniak, who told the Australian Financial Review last week that Apple shouldn't ditch the headphone jack unless it also improves the sound quality over Bluetooth wireless headphones.
If the reports are true, Apple is unlikely to get a sales bump on the scale that it normally does when releasing a overhauled iPhone.
Overall, Apple's iPhone sales in 2016 haven't been as strong as they were last year, and that's worried many investors who know that the majority of Apple's money comes from iPhone sales. If the reports are true, Apple is unlikely to get a sales bump on the scale that it normally does when releasing a overhauled iPhone. For example, those still using the iPhone 6 (or older) may find themselves unwilling to pay for more incremental updates, and may hold out for another year until the next model.
Then again, Apple is nothing if not surprising -- so hopeful phone buyers shouldn't go into mourning just yet.
