A new report is suggesting that the highly anticipated iPhone 5 will have a larger battery with a greater capacity. Photos scored by 9to5Mac show a battery which is apparently destined for the iPhone 5, and the images show a battery which has a capacity of 1440mAH, which is 10mAh greater than the 1430mAh found in the iPhone 4S battery and 1420mAh of the iPhone 4 battery. The voltage of the new battery is also increased slightly from 3.7 to 3.8.
The news is sure to please users of Apple’s iPhone 4S, which has not been a shining example of the longest battery life available on a smartphone. While Apple’s processor progression in the iPhone has been astounding, the battery life has been getting less and less, due no doubt to increased demands from greater processing capacity.
The iPhone 4S A5 processor uses a 45 nm manufacturing process, as does the A5X processor found in the iPad 3. However, the Apple TV 3 uses a 32 nm process, so it’s worth considering whether Apple will release an iPhone 5 with an A5X processor using a 32 nm manufacturing process, hopefully with a proportional increase in efficiency. If so, then battery life for the iPhone 5, expected to compatible with power sucking 4G, might not be as bad as one might think.
