Battery: The inside real estate is dominated by the battery. The 3.7V 1420 mAh Li-Polymer battery allows for up to seven hours of talk time on 3G or up to 14 hours on 2G. "It's pretty apparent that real estate was very limited inside the iPhone 4's 115.2 x 58.6 x 9.3 mm footprint," iFixit wrote. Antenna connector is on the back of the rear case cover.

Battery Connector: "The battery can be easily removed once the back panel assembly is out of the way," according to iFixit. The battery connector is different than the one in the 3G and 3GS: it is not soldered to the logic board
