A fresh set of images posted on Tuesday claim to show the battery Apple will use in its upcoming iPhone, and offer a size comparison with the unit found in the current iPhone 4S.

Coming on the heels of Apple's Sept. 12 special event announcement many believe is related to a next-generation iPhone, the images from repair site iResQ (via MacRumors) claim to show the handset's battery, one of the last remaining parts to be photographed amid a firestorm of supposed leaks.

The battery is apparently a "perfect fit" with the previously-leaked "uni-body" chassis, with the alleged part taking residence to the left of the logic board which was also recently pictured in August. In a side-by-side comparison with its current-generation counterpart, the supposed next-gen battery is taller and claims an output of 5.45 watt-hours at 3.8 volts, slightly higher than the 5.3 watt-hours at 3.7 volts on the iPhone 4S.

According to the repair firm, the so-called iPhone 5's battery is a little less than one half inch taller than the iPhone 4S unit, with both parts appearing to have equal thickness. The new battery also uses a different connector that is located opposite to the one on the iPhone 4S, most likely a result of the part's new positioning.

If the images are legitimate, Apple appears to be taking advantage of the extra internal space created by a switch to a larger 4-inch screen. While the exact power requirements of the expected in-cell display are unknown, the sixth-generation iPhone may see similar battery life when compared to current models due to power hungry LTE chips thought to be included in the upcoming handset.
