While it is difficult to comment on the authenticity of the photo, it is consistent with earlier reports, which too claimed that 4.7-inch iPhone 6 will feature a battery with a capacity around 1,800mAh. If it indeed is the case, then the iPhone 6’s battery capacity will only be slightly higher than iPhone 5S’, which features a 1,560mAh battery. While it may seem like a small bump, there is likely to be a greater synergy between the iPhone 6 and iOS 8, which could result in battery efficiency.
Apple is widely believed to be launching the first variant of the iPhone 6 sometime in September. The new iPhone 6 will feature some design changes including curved edges, a power button on the side rather on the right top-corner and elongated volume rocker instead of the circular volume buttons.
Apple was also said to be facing issues with the battery for the bigger 5.5-inch variant, which was solved yesterday. One of its new supply partners in Taiwan is reported to have found a way to develop a battery less than 2mm thickness and with a degree of flexibility too.
