While some people are still extremely eager to get their hands on a new iPhone 6 or iPhone 6 Plus this holiday season, others are already looking to see what could be in store for Apple next season, Forbes reported.

Each year, Apple releases new versions of its iPhone, but often the company releases a whole new phone every-other year. Apple often releases its main model and gives customers an added bonus with an "s" version.

The iPhone 6 was most impressive this year because of its massive size change. The iPhone 5s was a mere 4 inches compared to the 4.7-inch display on the iPhone 6. That's not even counting the gigantic 5.5-inch screen on the iPhone 6 Plus.

Did a new rumor surface about the next iPhone?

 

John Gruber, an Apple commentator, recently explained a possible rumor for next year's iPhone in his weekly podcast. Gruber believes that Apple could make its biggest-ever camera jump on the iPhone. The iPhone's camera has had little attention in the past few years, as competitors have put much better cameras in their devices. However, Apple could make a major move and release something completely innovative and new.

"The specific thing I heard is that next year's camera might be the biggest camera jump ever," said Gruber in his weekly podcast. "I don't even know what sense this makes, but I've heard that it's some kind of weird two-lens system where the back camera uses two lenses and it somehow takes it up into DSLR quality imagery."

Most popular camera in the world

 

What's interesting about this is that the iPhone is the most popular camera used in the world. According to Huh magazine, data from Flickr, a popular photo-sharing website, shows that the iPhone is used to upload more photos than any other camera device. In April 2013, Apple even released a commercial that backed up its device as the world's most popular camera.

"Every day, more photos are taken with the iPhone than any other camera," Apple stated in its commercial, according to Peta Pixel.

The iPhone 6 did have some changes to its camera from the iPhone 5 and iPhone 5s, Forbes reported. The new device includes "focus pixels," which provides a better autofocus function and optical image stabilizer. There have been obvious changes but nothing drastic that could truly take the image quality to a whole new level.

One thing has been certain with each new version of an iPhone: They have all kept a similar body and casing, the source reported. The iPhone 4s was barely different in size compared to the iPhone 4, and the same was true of the iPhone 5 and iPhone 5s.

Will Apple up the iPhone's megapixels?

 

According to Know Your Mobile, Apple has been quiet about adding megapixels to its device's camera. The new iPhone model could possibly switch to a 21MP sensor camera from its current 8MP. That kind of upgrade could be enough for Apple to get more people to buy the next iPhone upgrade.

When the iPhone 6 is opened, it is clear there isn't any room for a larger camera, Forbes reported. The phone's insides are completely full within its casing. For Apple to add a new camera, the smartphone manufacturer will have to get crafty.

With iPhone models upgrading each year, it's smart to invest in personal insurance to protect your device and so it can keep its value for an easy trade-in once the new model is released.
