iPhone 5 Teardown Reveals A6, Battery Specs, 1GB RAM and more

iPhone 5 teardown

Following the release of the iPhone 5 on Friday, iFixit went ahead and conducted one of their famous teardowns for Apple’s latest and greatest version of the iPhone. iFixit noted in their teardown that the iPhone 5 is tightly packed, far more than the iPhone 4S, likely because of the thinner and taller glass and aluminum enclosure.

Because the iPhone 5 is opened front-to-back, replacing a cracked screen is going to be easier than ever. Thank you, Apple!

Tools required to open up the iPhone 5 are a suction cup and a Pentalobe screwdriver, making it much easier to open than previous models. As noted, the iPhone 5 is still using Apple’s in-house Pentalobe screws, developed specifically to prevent third parties from dissecting the device.

For the iPhone 5, Apple has switched to a different battery chemistry, with a higher voltage and slightly larger capacity than the iPhone 4S. Let’s see how the battery specs stack up.

iPhone 5 Battery: 3.8V – 5.45Wh – 1440mAh. Talk time: Up to 8 hours on 3G. Standby time: Up to 225 hours.

iFixit removed the aluminum back and tore down every part, including the new 8 pin dock connector, the battery, the A6 chip, and the Qualcomm chip for LTE connectivity.

The A6 processor is the first Apple System-on-Chip (SoC) to use a custom design, based off the ARMv7 instruction set.

Because the A6 is not an ARM-specific CPU design, this gives Apple the ability to tailor the A6 towards their needs.

According to Chipworks, the B8164B3PM silkscreen label denotes 1GB Elpida LP DDR2 SDRAM.

Following their step by step teardown, iFixit ultimately gave the iPhone 5 a 7/10 for repairability, slightly higher than the 6/10 they gave the iPhone 4S. The full teardown video and summary from iFixit can be seen below.
