iPhone 4 Teardown

June 24, 2010 Hardware, Site News, Teardowns — Miro

We had a blast taking apart the new iPhone 4. Apple definitely spent time giving the phone a thorough makeover, meticulously changing every little facet.

We are happy to splay the fruits of their labor for your enjoyment!

You can view the teardown, or head to YouTube to check out our video slideshow.

Teardown highlights:

  • Like the iPhone 3G and 3GS, there are two silver Phillips screws at the bottom of the phone. But removing these screws releases the rear case instead of the front glass, giving you immediate access to the battery.
  • Unfortunately, the LCD panel is very securely glued to the glass and digitizer. If you break the glass, you’ll have to replace the glass, digitizer, and LCD as a single assembly.
  • The 3.7V, 1420 mAh Li-Polymer battery is not soldered in place, and is very easy to remove.
  • In what can only be described as a work of genius, Apple has integrated the UMTS, GSM, GPS, Wi-Fi, and Bluetooth antennas into the stainless steel inner frame.
  • The iPhone 4 sports two cameras — a VGA front-facer, and a 5 MP beauty on the back. Both are located on their own independent boards, making it possible to physically remove the cameras without damaging the phone.
  • The phone uses the 1 GHz ARM Cortex A8 core, much like its bigger sibling, the iPad.
  • Unlike the iPhone 3GS and iPad — which are both equipped with 256 MB of RAM — the iPhone 4 has a whopping 512 MB.
  • The AGD1 is the new 3 axis gyroscope that we believe is designed and manufactured by ST Micro for Apple. The package marks on this device do not appear to be the currently available commercial part, L3G4200D.
  • Broadcom provides both a BCM4329FKUBG 802.11n with Bluetooth 2.1 + EDR and FM receiver and a BCM4750IUB8 single-chip GPS receiver.
  • We’ve identified chips from Broadcom, Cirrus Logic, Numonyx, Samsung, ST Micro, Skyworks, Texas Instruments, and TriQuint.

  1. Hi there,

    nice one, good job!

    Thanks for that, very useful.

    But one question regarding the iPhone 4, what GPU is in the mobile phone?
    The same as in the iPad and iPod 3GS or better one?

    Then I ask you to do the same teardown for the Samsung S8500 Wave and I9000 Galaxy S.. :)

    Thanks in advance!
