iPhone 6 may be more expensive than iPhone 5S, according to an analyst.

Susquehanna International Group analyst Chris Caso claimed that iPhone 6 may deviate from the normal pricing strategy of Apple. The analyst suggests that Apple will raise the price over the traditional price of the iPhone. He said that the increase in price is due to the larger screen which will be seen in the next generation of iPhone. The higher price of the device would enable Apple to protect its gross margins, which would deteriorate otherwise due to increasing materials costs.

In addition, he thinks Apple will stay away from its traditional habit of lowering the cost of previous models when a new model comes out. Instead, Caso thinks that the company will design new products at lower price points. He also said that the launch of the iPad Mini with Retina display and the less expensive iPhone 5C are evidences that Apple is indeed moving in this direction.

Mr Caso also suggests that the iPhone 6 will be out by the middle of 2014. He stated that the iPhone 6 announcement may be three months earlier than the launch iPhone 5S. This suggests that we may see the next iPhone in June.

According to the latest rumours, the upcoming iPhone 6 features may include a solar wireless charging feature. One of the most common complaints on iPhones is fast depleting battery capacity. This feature aims to provide solution to the said problem.

This feature is supported by a patent filed by Apple back in February. Apple secured a patent for the use of solar panels in portable devices. This integrated touch sensor and solar assembly would involve integrating social cells into a touch screen by using electrodes that can pull double duty as a solar cell and a touch sensor.

Another rumoured feature that is making the rounds is the use of an extremely strong Sapphire glass for the smartphone's screen display. Apple already used the technology on the cover of iPhone 5S and Touch ID home button. Sapphire glass is roughly 2.5 times stronger than the glass currently used in smartphones, many of which use Gorilla Glass from Corning.

Also, the next Apple flagship smartphone may keep the iPhone 5S' 64-bit A7 processor, M7 graphics chip and the fingerprint sensor. The next generation of iPhone may also include features Near Field Communication and larger internal storage that were skipped in the current iPhone 5S.

The iPhone 6 release date is still unconfirmed. There were speculations that the unveiling will happen early next year. However, reports claimed that Apple is adding more suppliers to increase the availability of iPhone 5S due to its strong demand.
