    iPad Air teardown reveals smaller battery, separate LCD & cover glass



    A new dissection of Apple's latest tablet shows an iPad mini-like construction and several parts shared with the iPhone 5s.

    Repair experts iFixit found a new two-cell design design for the iPad Air's 32.9 watt-hour battery, a change from the fourth-generation iPad's three-cell, 43 watt-hour configuration. The iPad Air maintains its impressive battery life despite the lower charge capacity thanks to efficiency improvements in iOS and the new A7 processor, according to Apple.

    Also going on a diet, the device's 9.7-inch LG-manufactured Retina display has reportedly lost 20 percent of its thickness. Unlike the newest iPhones, the iPad Air's display is not laminated to the cover glass.




    As they dove deeper, iFixit noted the similarities in construction between the iPad mini and iPad Air, saying that it "seems like Apple took an iPad Mini and transmogrified it to a regular iPad's size."

    In addition to the similar construction, the iPad Air also gains a mini-like stereo speaker arrangement. The speakers contain no manufacturers identification, making it likely that they are a custom part.




    The iPad Air gains the nano SIM introduced with the iPhone 5, and swaps out the formerly Murata-made Wi-Fi module for a USI part, likely thanks to the tablet's new use of MIMO technology.

    Lastly, the iPad Air carries a slightly different model of Apple's A7 processor than the one found in the iPhone 5s. Benchmarks have shown that the iPad's variant of the chip has a minimally increased clock speed — about 100 megahertz — from the version found in Apple's handset.





    A full list of silicon found soldered to the iPad Air's logic board:

    Apple A7
    Elpida F8164A1MD LPDDR3 SDRAM
    Toshiba THGBX2G7B2JLA01 16 GB NAND Flash
    Apple M7
    Apple Dialog Power Management IC
    USI 339S0213 Wi-Fi Module
    Apple 338S1116 Cirrus Audio Codec
    Broadcom BCM5976C1KUB6G Touch Screen Controller
    Qualcomm M9616M Baseband Processor
    TriQuint TQF6514 RF Power Amplifier Module
    Three Skyworks SKY77-series LTE RF Power Amplifier/Duplexer Modules
    Two Avago A79-series LTE RF Power Amplifier/Duplexer Modules
    Murata Antenna Switch/Filter Module
    WTR1605L Transceiver Module
    Qualcomm PM8018 PMIC

    iPad Air teardown: never mind the repairability, feel the tech



    iFixit has done its usual trick of hopping over to Australia to get its hands on an iPad Air in the first time-zone to open its doors for business to bring us a look at the innards of the new device. The device is now on sale in the U.S. too, with supplies expected to be good.

    No surprise that the company found little prospect of success for DIY repair, reporting that even opening the casing was a challenge: when you pack that much technology into so small a space, there’s going to be a lot of glue involved.




    Some details of what the company found and more photos below the fold …

    The teardown confirmed Apple’s battery-life magic: the company has indeed replaced the three-cell 43 WHr battery of the iPad 4 with a less-powerful two-cell battery (32.9 WHr) to reduce the dimensions, while the more efficient A7 and M7 chips allow even greater battery-life.

    The A7 processor, though not given an X designation by Apple, is revealed to be a slightly different chip to the one on the iPhone 5S: marked as an APL5698 rather than APL0698.

    The Broadcom touchscreen controllers are found to be similar to those used in MacBook trackpads, while last year’s Micro-SIM is of course replaced by a Nano-SIM – all part of that quest to do everything possible to reduce the overall size of the tablet.




















    Repairability? 2 out of 10, mostly thanks to masses of glue and sticky-tape – again, the price you pay for the ultra-slim design.

    Check out the full details over at the iFixit site. As an aside for European readers, iFixit now has a European store, offering faster and cheaper shipping on its repair kits.

    Teardown shows only masochists should try at-home iPad Air repairs



    iFixit has a message for amateur mechanics who think they can repair their own iPad Airs: Don’t try this at home. After ripping apart the iPad Air and looking at its internals, the iFixit team found that Apple’s new tablet was almost impossible to self-repair and noted that the device’s arteries were clogged with a large amount of glue needed to keep the device together inside such a thin, compact frame. Specifically, iFixit found that removing the iPad Air’s battery was next to impossible and couldn’t get it done without warping the battery into a curved shape. On the plus side, however, iFixit did find that the iPad Air “is 20% thinner, 28% lighter, and 24% reduced in volume from the 4th-gen iPad,” so all that adhesive is going toward giving us the lightest and thinnest iPad yet.
