Even Apple's "iPhone 7" is still two months away from its upcoming launch, the gadget has already been surrounded by a slew of swirling speculations and criticisms.

On the list of the established speculations includes a potential dual-camera model, the lack of a headphone jack, the usual boring conjectures about antenna design, as well as processor speed and other geeky details.

But, a prolific and well-respected leaker is reasonably sure that the tech giant is planning to put an undeniably beneficial distinctive attribute in the "iPhone 7," which is a 1,960mAh battery that offers over 14 percent more capacity compared to the older versions, according to Maxim.

Putting it in perspective, the largest battery increase that the tech giant has ever made was from the "iPhone 5S" up to "iPhone 6," but it was designed to fit in with the needs of the jump from a 4-inch to 4.7-inch display - which means, it didn't equate to any battery gain in practice, Forbes reported.

The upgrade of "iPhone 7" is also the state of being strikingly different from last year, when the multinational technology company actually downgraded the battery of "iPhone 6S" to 1715 mAh from its predecessor's 1810 mAh battery.

The latest picture of the upcoming device that leaked online, appears to give Apple fans their clearest view yet of what the "iPhone 7" will actually look like.

The camera lens in in such a way is bigger, which gave assistance to rumors that Apple is improving the on-board snapper. Then, the lines across the back of the device have been removed, as the antenna appears to have been moved to the corners of the gadget.

However, it's impossible to distinguish from the image, whether or not the headphone jack has remained in place. The removal of the headphone jack has been the biggest rumor surrounding the upcoming smartphone and a number of the tech giant's fans aren't happy with the idea of losing it, based on the report of Mirror.
