iPhone 5 could get September release date

The iPhone 5 is rumoured to launch in September, one month earlier than what has been expected.

The iPhone 4S was released in mid-October last year, and industry watchers expect Apple to release a new device a year after the previous device's launch.

The expected release could be pushed up because of the expected releases of competitive products, like Windows RT-powered tablets, in September and October.

Nokia World will also take place in September, meaning we should see the announcement of Noki's first Windows Phone 8-powered devices.

Samsung is also rumoured to be launching its second-generation Galaxy Note in September too. We could also see a new Nexus-brand handset from the Korean manufacturer as well. Google will no doubt be keen to have a launch handset in place for the roll-out of Jelly Bean.

One issue that could change the release date is Apple's concern with the battery. According to Brian White, an analyst at Topeka Capital Markets, the unnamed supplier of the iPhone 5's batteries has yet to meet Apple's expectations. The report suggests that only 30 percent of the batteries produced currently meet Apple's standards.

The iPhone 5 is expected to have 4G LTE capability as well as a newly redesigned dock connector with only 19 pins. Reports also say that the next iPhone will have a 4-inch display, larger than the current 3.5-inch display, and a resolution of 1,136 x 640 pixels with a 16:9 aspect ratio.
