The crew at iFixit has given the iPhone 4S its proper tear-down, revealing the phone’s inner workings and hardware. iFixit noticed that the battery offers an extra 0.5 WHrs over the one found in the iPhone 4, which is likely the reason Apple is able to advertise an additional 1-hour of 3G talk time on the iPhone 4S compared to its predecessor. The phone is equipped with a Qualcomm RTR8605 radio, an Avago ACPM-7181 power amplifier and of course a dual-core 1GHz Apple A5 processor, which has been downclocked to 800MHz. Be sure to hit the jump for a few more images of the iPhone 4S teardown. Deliveries of Apple’s new smartphone begin on Friday, and in the meantime be sure to check out our hands-on with the iPhone 4S.
