I honestly thought that we were done with the iPhone 5 rumors and leaks. There seems to be nothing else to divulge about Apple’s new wonder device. Everything has been leaked and nothing will be a surprise when the device is finally revealed. Well, it seems that I spoke too soon.

9to5Mac got a hold of some images that seem to be the new battery that will power the iPhone 5. It wouldn’t be that exciting if it weren’t for the fact that the new battery features some promising upgrades from previous models.

According to the source, the new battery is thinner and features a higher capacity of 1440 mAh. The iPhone 4S had a battery with a capacity of 1430 mAh. It has a voltage of 3.8, which is up from a voltage of 3.7 on the iPhone 4S. It also has a watts-per-hour measurement of 5.45, which is up from 5.3 on the iPhone 4S.

If none of that made sense to you, just know this: the new iPhone is going to last longer than previous models. There were some prior reports that indicated the iPhone 5 as having battery production problems. Today’s leak seems to indicate that the batteries being produced now are finally up to Apple’s standards.

As 9to5Mac points out, however, the increased battery may also be due to 4G LTE. It requires a larger battery and the new capacity featured in this battery would be enough to push a LTE connection without having to sacrifice general power use.

Like all rumors, nothing is absolutely confirmed until Apple shows off the iPhone 5 at its rumored September 12 reveal. That being said, there’s a good chance that the majority of these leaks and rumors are real. If the rumors do turn out to be true, we could be getting a pretty awesome phone from the guys at Cupertino.
