Battery And Comm
According to the company's claims, Apple has improved the battery life of iPhone 5 by leaps and bounds compared with the iPhone 4S. It says browsing time goes to eight continuous hours on 3G, up from six hours, and to 10 hours on Wi-Fi, up from nine. Standby time increases to 225 hours from 200 on 4S. Respective video and music playback times remain at 10 hours and 40 hours for the devices, while estimated LTE browsing time is expected to be eight hours. It's able to handle all this despite a processor that's supposed to deliver double the application speed and graphics performance and a battery-zapping 4G radio. As in the 4S, iPhone 5 supports Bluetooth 4.0 and Wi-Fi a/b/g/n, but it adds support for the 5.0GHz frequency for connections up to 150 Mbps and interference coping.
Like the 4S, the iPhone 5 will be available in 16 GB ($199), 32 GB ($299) and 64 GB ($399) models. Pre-ordering begins Sept. 14 in advance of shipments to launch a week later.
