Apple's iPhone 6 is apparently being unveiled on September 9th, and although we'd gathered plenty of details already, we've now got some unofficial confirmation of several key features. It's naturally assumed, given the A7 processor of the iPhone 5s, that Apple will bundle an improved A8 chip into the next handset, and along with improved Wi-Fi and Touch ID, this will definitely be the case.

Like most of the changes that have been made to the iPhone through the generations, the improvement in the battery capacity of Apple's smartphone has been meager at best. Sure, tweaks to the processor and other optimizations have allowed the battery retention to improve, but given that the next-gen handset looks set to include a larger display, NFC and other improvements, there's no doubt that the battery's capacity must also increase to cope with the workload. We've heard reports that the 4.7-inch model will include a battery of around the 1,900mAh mark, with that number changing dependent on the source, but with around one month to go until the purported announcement, it would appear that the figure may be as high as 2,100mAh.
