As previously reported, the battery inside the iPhone 6 could be only 2mm-thin. The new handset itself may be 7mm-thin - a tad skinnier than the 7.6mm iPhone 5s.
The iPhone 6 is expected to be announced in September, in two versions: one sporting a 4.7-inch display, and another one featuring a larger, 5.5-inch screen. Both versions have been allegedly pictured recently (see here and here), although for now we can’t be certain that those photos are legit.
DigiTimes has it that Apple could sell 60 to 70 million new iPhones by the end of 2014. Since the Cupertino company sold a total of 43.7 million iPhones in the first quarter of the year, those numbers don’t seem unrealistic.
