Leaked pictures claiming to be of the iPhone 5 battery show that its capacity will be virtually identical to that of the iPhone 4S. And without other optimisations, it's likely to provide worse battery life.
Photos received by 9to5Mac that claim to be of the iPhone 5 battery show that it has a 1440mAh capacity, up just 10mAh from the iPhone 4S's 1430mAh model. Although consistent with the increases of previous-gen iPhones - the iPhone 4 had a 1420mAh battery - it leaves us wondering whether it will be enough.
The conjecture consensus is that the iPhone 5 will have a larger, widescreen display with a 4in diagonal. Those pixels need power. And while it's not a concern for us in the UK, the rumoured LTE version of the phone could potentially struggle with such a modest battery. LTE is an alternative to 4G, and is available in the US.
There are two possible solutions to allay our concerns. The first is that the iPhone 5's processor will be minutely tuned to make additional power consumption a non-issue, or iOS 6 may work harder to increase battery performance.
As Apple showed in the new iPad's design, which gained significant weight in order to maintain battery life, Apple is unlikely to let stamina slip in the iPhone 5. The next iPhone is expected to launch on September 12.
