Apple has released another TV ad for the iPhone 4 in the U.S., this time bragging about its battery life. The ad begins by stating that the iPhone's lithium polymer battery lets users "work longer, play longer, laugh longer..." and so on while showing off features like email, gaming, video and so on.
The first batch of iPhone 4 ads described FaceTime, while the previous spot, entitled "Every," turned the focus to hardware; specifically, the Retina Display. This ad (still untitled as it hasn't yet appeared on Apple.com) continues that trend by showing off the powerful battery, while slipping in software features as well. You can see it in its entirety after the break.
