Photos and video of a purported 2,915 mAh battery for the iPhone 6 have surfaced online, reports Nowhereelse.
The format of the serial number printed on the hose that connects the battery to the motherboard of the device is indeed similar to the format used by Apple (820-4545-03 820-3230-03 for the battery and for that iPhone 5). Note also that this hose connector fits perfectly to that found on the motherboard of the iPhone 6 to 4.7, and 5.5 inches
At this point in time, it’s believed that the 2,915 mAh battery is intended for the 5.5-inch iPhone 6; whereas, a smaller 1810 mAh battery is predicted for the 4.7-inch model. The iPhone 5s battery has a capacity of 1,560 mAh.
