The iPhone 6 set for release date in 2014 could introduce killer features such as charging-on-the-go and a whopping RAM provision of up to 4GB, likely making the iOS device as the most advanced iPhone build to come out of Apple's production lines.

Such possibilities were hinted by a new Apple patent on mobile device power management and a cutting-edge memory chip technology that one of the tech giant's major suppliers has reportedly developed and is geared for wide-use next year.

According to Patently Apple, 4GB or higher RAM for the next iPhone has become a reality thanks to the 6-gigabit capacity chip that memory chipmaker SK Hynix has successfully developed.

Embodied in a low-power DDR3 memory module and employing a 20-nanometre processing technology, "the latest development will help us expand our territories in mobile devices with an expanded data storage capacity," SK Hynix was reported by Patently Apple as saying.

While the new memory chip is able to handle a top-speed of 14.8GB per second, it is not a power-hog, according to the same report, which is one of the main factors for Apple to finally adopt the technology.

In theory, Apple's upcoming iPhones and iPads should benefit from having more RAM provisions on board when the 64-bit A7 CPU was ushered in via the iPhone 5S but the feature, at the moment, is seen to put too much pressure on battery juice.

But with the SK Hynix breakthrough, the concern has been addressed with, likely paving the way for an iPhone 6 that will boast of capacious and speedy RAM system. It is understood that deployment of the new memory chips in 2014 will simultaneously be seen on iPads and iPhones.

Yet the iPhone 6 is likely to display first the new mobile device power system that Apple has invented, a separate Patently Apple report said, pointing to a freshly-published patent application of the tech giant.

The report dubbed the power management feature as a "Portable Solar Panel Accessory for Recharging Devices on the Go."

The system is primarily designed to draw energy from a power adapter and a solar panel then run a gadget by converting the harvested energy "into a voltage, current, and/or form that are compatible with the battery and/or components of the electronic device."

But the system's uniqueness lies on its being fully functional without a power converter, allowing mobile devices with the power management feature to recharge even when not hooked up with a power outlet or seated on a charging plate.

Obviously, Apple is envisioning uninterrupted iOS device gadget use by including mobile charging with the new breed of iPhones and iPads. With the feature, the tech giant also aims to supplant the wireless charging capabilities introduced in late 2012 by a number of Android and Windows 8 handsets.

And these new killer features would manifest first through the iPhone 6, which on its rumoured Q3 2014 release date is believed to sport a 4.9-inch screen, marking Apple's entry into the phablet arena but with emphasis on one-hand use.
