The experts at iFixit earlier today posted an iPhone 5s teardown, exposing the innards of Apple’s next generation iPhone, revealing the TouchID fingerprint sensor, the larger battery and the much-talked about A7 chip.
iFixit got their hands on a gold iPhone 5s, and quickly tore it down. Here are the highlights of the teardown:
- As they tried to ditatch the display assembly from the rear case, iFixit found that there’s a cable at the bottom of the iPhone 5s that connects the new Touch ID fingerprint sensor in the home button to the Lightning port assembly.
- Here’s the fingerprint sensor in all its glory. It is composed of a CMOS chip, and a bunch of capacitive sensors to do the actual “sensing.” iFixit expresses concern over the ability of the sapphire crystal to protect the sensor:
- And here’s Apple’s all-new 64-bit A7 chip that promises to make apps much faster and games much better looking thanks to an improved GPU. Chipworks, separately found out that the A7 chip is manufactured by Samsung: “We have confirmed through early analysis that the device is fabricated at Samsung’s Foundry and we will confirm process type and node later today as analysis continues. That being said, we suspect we will see Samsung’s 28 nm Hi K metal Gate (HKMG) being used.”
- Although iFixit couldn’t find the M7 motion coprocessor, the experts at Chipworks found the chip in their own teardown, which turned out to be manufactured by NXP Semiconductors.
- The battery is slightly larger at 3.8V – 5.92Wh – 1560mAh as compared to the iPhone 5’s 3.8 V – 1440 mAh – 5.45 Wh battery.
Largely, the internal layout of the iPhone 5s is very similar to the iPhone 5, with the iPhone 5s sporting marginally bigger batteries and slightly narrower logic boards. iFixit gives the iPhone 5s a repairability score of 6 on 10, with 10 being the easiest to repair, as compared to the iPhone 5’s score of 7. The firm notes that the battery can no longer be easily pulled due to a stronger adhesive, and the fingerprint sensor can easily be ripped out of its socket while detaching the display.
