Apple’s supply chain for the next iPhone 4G is getting weaker every other day. In past we have seen White iPhone 4G panel leaks at ubreakfix, Chinese site and outer panel at Portugal site. Now, some images of iPhone 4G batteries have been leaked.

The new images clearly shows that the next-generation iPhone 4G’s battery carries a capacity of 5.25 watt-hours, a nearly 16.5% increase from the 4.51 watt-hour battery in the iPhone 3GS. However, the Vietnamese leaked prototype, carried a 5.00 watt-hour battery. On balance, according to rumors, it seems that finally we will have an iPhone that will run during the day and in times of need.

The images of the forthcoming iPhone’s dock connector and cable has also been posted, which slightly differ in design used in the iPhone 3G and 3GS.
Though, the iPhone 4G battery and dock connector appears to be legit but cannot be ascertained to be the actual retail model which Steve Jobs will unveil at WWDC which begins on June 7th. May be, the parts are of Chinese iPhone 4G clones. Who knows? For more rumors on iPhone 4G, please visit here.
