Apple iPhone 4S internals: Tearing down the iPhone 4S

Apple released the iPhone 4S on October 12, 2011. Although, its exterior is similar to iPhone 4, Apple has made lots of new changes in terms of internal hardware.

This post features the internal hardware of iPhone 4S as bisected by ifixit.

  • 01 - iPhone 4S Unboxing: The iPhone 4S is available in 16GB, 32GB, and 64GB models. It comes in black or white. In the U.S., the iPhone 4S is available from AT&T, Sprint, and Verizon. When purchased with a two-year contract, the 16GB model costs $199, the 32GB model costs $299, and the 64GB model costs $399.
  • 02 - the Apple iPhone 4S has an Apple A5 1GHz dual-core processor with 512MB of DDR2 RAM, 16GB of storage, 8MP rear-facing camera, VGA-quality front-facing camera, and 3.5" Retina display (960x640-pixel resolution at 326 ppi).
  • 03 - The iPhone 4S has two tamper-resistant pentalobe screws along the bottom edge. I used a special screwdrive to remove them.
  • 04 - Like its exterior, the iPhone 4S' internal hardware layout is nearly identical to that of the iPhone 4. Also, shows the iPhone back cover.
  • 05 - iPhone 4S 3.7V 5.3Whr Battery
  • 07 - 8MP rear-facing camera.
  • 08 - Although their internal design is almost identical, the Apple iPhone 4S was a bit more difficult to dissect than the iPhone 4--mainly because the display/front panel assembly didn't want to come off.
