Apple is exploring new battery technology and manufacturing techniques for use in building its first phablet release next year, the 4.8-inch iPhone 6, a new set of patent applications by the tech giant showed.

Once deployed, Apple will inch closer to the wrap-around iOS device patent approval it recently won from the U.S. patent authorities, paving the way for iPhone and iPad models that are physically redesigned.

The battery technology opens the door for a new device manufacturing approach that allows the use of "unorthodox battery designs with curved cells and irregular shapes," Apple Insider said in a report.

In the process, consumers can expect the upcoming generation of iOS devices to sport thinner, slimmer and lightweight profiles. Future batch of iPhone and iPad renditions could also come in radical forms, starting off with the iPhone 6, the same report said.

Touted as the first Apple smartphone to slug it out with other oversized smartphones, the iPhone 6 is believed set for a June 2014 release date, flashing new form and features that will see the elimination of the iconic Home button and the introduction of more gesture-based device manipulation.

The new patent filings are titled 'Curved battery cells for portable electronic devices' and 'Non-rectangular batteries for portable electronic devices'. The main objective attached with the cutting-edge technology is the creation of Apple gadgets that defy existing convention on device manufacturing.

Clearly, Apple is seeking to reinvent its product lineup by re-engineering the process of their production, the report said.

"In some embodiments, the curve is formed to facilitate efficient use of space inside a portable electronic device," the tech giant said on its filing before the U.S. Patent and Trademark Office.

"Both techniques aim to shape a battery that fits snugly into a device's housing, thereby reducing wasted internal space," the report said.

The technology is in line with the prevailing trend of consumer electronic products that are short on footprints but long on features and prowess.
