While many are still awaiting the arrival of their iPhone 4S devices, some people have not just gotten their hands on the devices, they’ve already destroyed it. Such are the ways of iFixit, which likes to teardown these sorts of things.

Unlike iSuppli, which will undoubtedly do its own teardown, iFixit doesn’t attempt to estimate the bill of materials cost of a device. Instead, it just tears down a device and lets us know that Apple (or any other manufacturer) has stuffed inside.
Notably, Apple is still using pentalobe screws, something that’s been highlighted before. These types of screws aren’t standard, but coincidentally iFixit sells one.
There are a number of things known about the iPhone 4S internals, including its processor, an A5 SoC, an upgraded 8MP rear-facing (1080P video capture) camera (same VGA front-facing camera), the same retina display, and more. There are plenty of things that aren’t known, until now.
For one, the iPhone 4S has a continuous talk time of 8 hrs on 3G (up one hour from the iPhone 4), up to 14 hrs on 2G (the same) and up to 200 hrs on standby (oops, 100 hours less). The battery itself only offers an extra .05 WHrs in the battery over the iPhone 4, so despite the drop in standby time, considering the hardware improvements, it’s not a bad trade-off.
Despite the similarity in the exterior of the devices, iFixit says the 4S battery cannot be put into a 4.
Another open question has been how much RAM (not storage). As assumed, it’s the same as in the 4S, or 512MB, iFixit confirmed.
- Qualcomm RTR8605 Multi-band/mode RF Transceiver.
- Skyworks 77464-20
- Avago ACPM-7181 Power Amplifier
- TriQuint TQM9M9030 Multi-Mode Quad-Band Power Amplifier Module.
- TriQuint TQM66052 (possibly a PA-Duplexer Module)
- Qualcomm MDM6610 chipset (an upgrade from the iPhone 4’s Qualcomm MDM6600)
- Apple 338S0973 Power Management IC
- Toshiba THGVX1G7D2GLA08 24nm MLC NAND flash memory
Since Apple had two different designs to base its new iPhone 4S on, there are some things that are Verizon iPhone like and Some things that are AT&T iPhone like (remember, this year we have one set of hardware for all the carriers). For one, the vibrator motor is the linear oscillating vibrator from the Verizon iPhone 4 as opposed to the rotational electric motor with counterweight found in the AT&T version iPhone 4.
Also, earlier iFixit noted (in its Verizon iPhone 4 teardown) that the Verizon and AT&T iPhone 4 display assemblies had different mounting tab locations. The iPhone 4S uses the same one that was found in the AT&T version.
And, speaking of the display, it’s the same display in the iPhone 4. That means Apple calls it a “retina display,” a term debunked by a display expert. That said, it’s still a great display.
Now, we await the teardown by iSuppli, to see just how much this baby is costing Apple to build.
