According to AnandTech, the iPhone 5 will come with technology that will help to increase the battery life of the phone in the form of the Broadcom BCM4334 chip.
iPhone 5 rumored to get BCM4334 chip, thinner battery makes room for LTE antennas
Currently Apple devices have the BCM4330 chip which is found in the iPhone 4S and the iPad. It is said that the new chip has the 40nm process which is very efficient, as opposed to the older chip with a 65nm process. For those who are not technology minded what this means simply is that the lower the nm, the better battery life users get thanks to power profile reduction.
Broadcom said that they have been working on the BCM43330 design of the chip and have refined it, reducing power by another 40% to 50%. They have also made a reduction by 3 orders of magnitude which have dramatically helped to reduce power in standby. Broadcom gave an example of reduction, the BCM4330 when in full Rx mode uses around 68mA. On the other hand the BCM4334, with the same voltage uses 36mA.
The Broadcom chips are generally used in devices such as tablets and phones to power Wi-Fi capabilities and should be able to save power for iPhone users who are on W-Fi. Another bonus to the chip is that it will help to make the battery of the new iPhone thinner. The power savings will offset the fact of the rumored larger screen and LTE radio and it will also have dual band Wi-Fi complete with Wi-Fi Direct. The device will provide users with advanced switching techniques which allow dual band operation which will simultaneously be able to support one band with network connectivity and at the same time allow streaming of content through Wi-Fi display along with Wi-Fi direct. Of course Apple has their own Airplay so it is very unlikely that they will use Wi-Fi display.
The iPhone 5 has been rumored to be released sometime during fall of 2012, with iOS 6 expected to be unveiled at WWDC 2012. We’ll keep you posted as more develops.
