Photos of iPhone 5 Battery in Rear Shell, Compared to iPhone 4S Battery

While photos of the iPhone 5 battery have leaked several times in recent weeks, repair firm iResQ has now obtained one of the batteries and posted new photos showing the battery in the iPhone's rear shell and next to an iPhone 4S battery for comparison.

As previously seen, the iPhone 5 battery runs at 3.8 volts, potentially using new chemistry to boost capacity to 5.45 watt-hours from the 3.7-volt 5.30 watt-hour battery used in the iPhone 4S. The comparison photos show that the new battery is slightly taller than the iPhone 4S battery, and the thickness appears roughly the same despite the fact that the new iPhone is expected to be at least 15% thinner than the iPhone 4S.

Key differences between the iPhone 5 and the iPhone 4S battery:

1. The iPhone 5's battery is slightly less than a half an inch taller than the iPhone 4S. The thickness appears to be identical.

2. The iPhone 5 is 3.8V/5.45Whr while the iPhone 4S is 3.7V/5.3Whr.

3. The connector on the iPhone 5 is not only different, it is placed on the opposite side of the battery to accomodiate its new position within the iPhone.

Apple is expected to introduce the iPhone 5 at next week's media event that was officially announced today.

The same thickness?! Now that actually IS INTERESTING people. The ability to drop the phone from 9.3 mm to 7.6 mm thick, but still keep the same internal height is really insane.

This implies the faux-unibody design and the InCell technology greatly reduced the overall thickness. As opposed to the internals. Interesting.

Well done Apple. :apple:
