Rumors continue circulate about the upcoming iPhone 6. Now, just after the new beta for the upcoming Apple operating system was released, experts say the new iPhone could be packed with a number of interesting features.

So far, reports have been swirling that the successor to the iPhone 5 will have a more powerful processor under its hood. International Business Times notes that the iPhone 6 may be powered by an A7 quad-core processor, which is faster than the previous iPhone and could be a better pair for the soon-to-be released iOS 7.

Apple may also be upgrading itthe iPhone's internal storage. What was once the largest storage option -- 64GB -- is now expected to increase to 128GB.

A better camera is almost a sure addition to the upcoming smartphone. While nothing has yet been confirmed, reports say the iPhone 6 will come with a 12-megapixel camera with low-light shooting ability and an HDR setting.

Expert Reviews also says that Apple could be looking to expand the screen size of its upcoming device. Word is that the iPhone 6 will have a 4.8-inch screen, comparable to the Samsung Galaxy S4.

IB Times also notes that with the introduction of an audio-only FaceTime app, it could be safe to say that the Cupertino-based company will also incorporate better speakers. A better battery capacity is also seen to be a great fit for the new device.

As reported earlier, the new iPhone 6 may also carry a new security feature: a fingerprint sensor. While Apple will not be the first one to incorporate this technologically advanced feature, it could still be a great addition to what is already an amazing phone.

The new iPhone 6 is expected to be released in early Septemeber.
