Apple will surely stuff the iPhone 6 on its release date, tentatively set on September 19 2014, with the expected killer handset features and three of them got fresh backings on the road to reality.

Slim iPhone 6 build thanks to ultra-thin battery

Crucial to the rumoured super-slim iPhone 6 finish is the battery - the thinner it is, the likelihood that the device will touchdown on its leanest and lightest ever. That likely will happen, according to CNET, which picked up the latest post from blog site NowhereElse.fr that claimed the next iPhone battery is trimmed down further from the last seen in the iPhone 5S.

The capacity, however, is bumped up from 1560mAh to 1810mAh and the slight juice jump is best explained by Apple's strict manufacturing requirements for the iPhone 6. It appears that the rating cannot go any higher, which is line with the blueprint of assembling this 2014 the thinnest iPhone ever.

13MP iSight shooter

Earlier reports have suggested that the 8MP ream camera that Apple has introduced with the iPhone 4S and was carried over through the iPhone 5S will be ported to the iPhone 6 but with significant hardware and software enhancements.

That plan could change, according to G4Games, which reported this week that Apple may just update the next iPhone camera with a Sony-made sensor of 13MP. The same package is also seen to contain optical image stabilisation feature that for users will translate into the easy production of high-quality clips and images.

Sapphire display exclusive for 5.5-inch iPhone 6 phablet

Sapphire glass cover is definitely a part of the new iPhone launch but according to JP Morgan Securities, the deployment will be initially limited. In a latest note, the investment firm told The Taipei Times that only 10 million units of sapphire glass cover will be ready in time for the iPhone 6 rollout.

As a result, Apple will have to limit the materials use to that of the bigger iPhone 6 model. "Sapphire covers will also be restricted to high-end iPhones, possibly the 128GB ones," said the JP Morgan report.

Now it should be noted that in one of his research notes, KGI Securities analyst Ming-chi Kuo predicted that Apple will sell a 128GB variant of the 5.5-inch iPhone, which he said will distinguish it from the 4.7-inch edition. It appears now that another exclusive for the jumbo-size iPhone is the extra-strong sapphire coating - that is if the JP Morgan report will prove correct.

As mentioned, the iPhone 6 release date is scheduled for mid-September 2014 but this could only be for the 4.7-inch as the 5.5-inch rollout, according to Kuo, could be pushed back to January 2015.
