Intrigued about what makes your iPhone 5S tick? You probably know all about its Apple A7 processor, storage, the retina display with 325 ppi, and other tech specs. But, have you actually seen how they look inside the iPhone 5S? Don’t bother tearing down your device piece by piece just to look inside and find out. We’ll take it apart for you to see what’s inside the iPhone 5S, thanks to iFixIt.
The Dissection Begins
After unlocking the pentalobular screws that secure the phone shell into place—and lifting off the front shell cover—a cable is noticeable at the bottom. It attaches the Touch ID sensor found in the home button to the Lighting receptacle or port assembly. This cable is among the crucial parts of what’s inside the iPhone 5S and should be handled with care.
Once you take out the components off the shell, you get to see the overall internal layout and intricacies of the 5S. You’d see that it has little difference to the iPhone 5, among which is the absence of a removal pull-tab for the battery. With the 5S, the battery is protected with some metal connector covers and is fixed in place with some adhesive agent. Somewhere near is the 326 ppi Retina display connected with the FaceTime Camera, the LCD cables, and the digitizer.
Home Button and Touch ID
The Touch ID is Apple’s latest fingerprint scanner. Being a CMOS chip, it is basically a miniscule cluster of tiny capacitors that forms an image of the rim, crests, and creases of your finger, specifically the thumb. The sensor saves your fingerprint data and is protected by a sapphire covering.
Next, we see the iSight camera. This is among the most exciting of what’s inside the iPhone 5S. In the case of the 5S, the back of the camera is labeled DNL33341WGRF 4W61W. This DNL label, according to Vice President Jim Morrison of the Technology Analysis Group, confirms that the cam modules are indeed of the Sony IMX145, which is consistent with the iPhone 5S specs.
The speaker assembly appears slightly easier than that of the iPhone 5, and that means the headphone jack, microphone, and lighting connector cluster come out as easily. However, if there’s any need for replacement, you have to replace the whole thing because it is modular in design.
Then there’s the updated dual flash or the amber and white LEDs. This dual-flash balances the overall photography quality taken at night. Sometimes, ordinary flashes result to ghostly tones in pictures due to reflections from the flash.
Looking into the tiny networks of ICs and capacitors, you’d see that the Wi-Fi module is a Murata 33S0205 and, according to Chipworks, is consistent with the Broadcom BCM4334. The Murata IC seems to be used for both iPhone 5 and iPhone 5S. Aside from it, there is also the SK Hynix H2JTDG8UD3MBR 128 Gb NAND Flash and the Qualcomm PM8018 RF for power management IC. Other iPhone 5S ICs are TriQuint TQM6M6224, Apple 338S1216, Broadcom BCM576 for the touchscreen controller, Skyworks 77810, and the Texas Instruments 37C64G1.
IC devices seem to dominate the rest of what’s inside the iPhone 5S: you also find skyworks 77355, two Avago ICs A790720 and A7900, and Apple 338S120L.
Logic Board Backside
If you turn the logic board to its backside, you find the Apple A7 APL0698 SoC, the Qualcomm MDM9615M LTE modem, and the qualcomm WTR1605LLTE/HSPA+/CDMA2K/TDSCDMA/EDGE/GPS transceiver.
The iPhone 5S display is easiest to take out of the phone body and that says a lot about its repairability, particularly easy screen replacement. The digitizer and LCD, particularly, are one piece with the front glass.
So there you have a gist of what’s inside the iPhone 5S and what stuffs make it tick. If you’re familiar with other devices, you also get an idea about how differently the 5S is from other iPhone models and other brands. [via]
