While the iPhone 4 boasts a larger battery than any previous iPhone, it also brings with it several new features that could be battery draining. So, just how does battery life stack up in the real world compared to its predecessors?
Teardowns of the iPhone 4 have shown that nearly half of the space inside the case is occupied by a large battery; a 1470mAh (milliampere-hour) battery to be precise.
It is 16% larger than the 3GS battery, which was the previous largest at 1270mAh. This means we should see a 16% boost in battery life over the 3GS; however, the 3GS didn’t ship with the promise of multitasking apps, dual cameras, Retina display and a penta-band radio. With the iPhone historically being a “charge daily” kind of phone, many users want to know how the iPhone 4’s battery life stacks up when compared to previous models.
