Measured diagonally, the Android screen size is 6.5″ in the full rectangle and 6.4″ with accounting for the rounded corners. Actual viewable screen area is less due to the rounded corners and camera lens. Actual battery life depends on factors such as network, features selected, frequency of calls, and voice, data, and other application usage patterns.
