Above we have a couple of examples of the camera, compared with the 3GS camera, as close to a comparison as I could achieve working with a live subject, they do say never work with animals and reviewers.
Apple use a built in Lithium-ion battery in the 4S and rate the phone for 8 hours of talk time on 3G with standby noted as 200 hours. For Internet use Apple suggest 6 hours on 3G, 9 hours on Wi-Fi and video/audio playback is a 10/40 hour split. Speaking of audio and video the 4S supports all of the formats we would expect including 320KPBS AAC, MP3 and lossless as well as H.264 (.mov) video and MPEG-4.
Here are our initial battery testing results on the initial charge.
