    • Before digging our digits into the One, we pause to count up its specs:

    • 5.5" IPS display with a resolution of 1920x1080

    • 13 MP f/2.0 rear-facing camera with dual-LED flash along with a 5 MP front-facing camera

    • Qualcomm Snapdragon 801 processor with 2.5GHz Quad-core CPU

    • 3 GB LPDDR3 1866 MHz RAM

    • 64 GB eMMC 5.0 storage capacity (also available in 16 GB)

    • 802.11b/g/n/ac Wi-Fi, Bluetooth 4.0, USB OTG, GPS/GLONASS, NFC

    • Impressive hardware, to be sure—but this here’s a teardown, and the number One has left us a bit traumatized of late. Here’s hoping the “Plus” stands for “more repairable than phones of yore…"

    • Designed by OnePlus and assembled in China, the OnePlus One is identified as model number A0001.

    • The One is powered by a custom version of Android, CyanogenMod 11S, created by Cyanogen, Inc.

    • What's so special about CyanogenMod? It's an open source operating system for smartphones and tablets based on Android. It offers features and options not found in Android versions distributed by mobile vendors.

    • The OnePlus One is the second phone to come preinstalled with CyanogenMod, the first phone being the OPPO N1 CyanogenMod Edition.

    • We're pretty excited to see the One has an open source OS and is completely unlocked, both of which protect the rights of consumers.

  3. OnePlus One Teardown: step 3, image 1 of 2 OnePlus One Teardown: step 3, image 2 of 2
    • Compared to the current top-selling smartphone, the iPhone 5s, the One is slightly thicker at 8.9 mm (vs. 7.6 mm) and significantly taller at 152.9 mm (vs. 123.8 mm).

    • While this isn't quite a phablet, reviewers are saying this One's a tad big for single-hand use. Unless, of course, you're the Hulk.

    • Lookie here! What's in this red box?

    • A power adapter and a fancy USB cable with an inside-out connector, has OnePlus finally defeated the USB plug scourge?

    • Oh and a SIM eject tool with keychain caddy. Because, how many times have you wished you had an eject tool hanging off of your keyring?

    • Never? Same here. But it sure looks cool.

    • The nigh invisible SIM slot opens with the touch of said fancy eject tool, and we've breached the perimeter of this monolith.

  5. OnePlus One Teardown: step 5, image 1 of 2 OnePlus One Teardown: step 5, image 2 of 2
    • With that, our plastic opening tool is ready to attack!

    • The One presents no obvious point of entry, but since OnePlus will offer interchangeable back plates we decide to start at the back case. We wiggle our way into a seam to see what's what…

    • …and to our delight, the back plate comes off readily—with just a bit of resistance from a few clips around the edge.

    • While interchangeable parts are always a plus for repairability, we don't expect the back to be prone to the same catastrophic failure as the front glass.

  6. OnePlus One Teardown: step 6, image 1 of 2 OnePlus One Teardown: step 6, image 2 of 2
    • Baby's got back…case, that is. With the back case free, we see the first glimpse of the embedded rechargeable 3100 mAh LiPo battery.

    • At first glance this One seems to have a heftier, and more accessible, battery than the other One.

    • This back case is a gold-laced antenna party.

    • Spring contacts in several places join three gold antennas plus one NFC sticker antenna to the phone body.

  7. OnePlus One Teardown: step 7, image 1 of 2 OnePlus One Teardown: step 7, image 2 of 2
    • We poke at the giant red battery for a bit (reenactment of actual events) until we finally succeed in popping it up with a spudger.

    • Alas! It seems our reach has temporarily exceeded our bite, as the battery cable disappears under a screwed-in panel.

  8. OnePlus One Teardown: step 8, image 1 of 3 OnePlus One Teardown: step 8, image 2 of 3 OnePlus One Teardown: step 8, image 3 of 3
    • No matter—out go the first round of screws, thanks to our Pro Tech Screwdriver Set.

    • But it's not over yet! The One deals us a one-two punch with some hidden screws.

    • We don't take kindly to screws hidden under rubber stoppers around here. And that last screw is sporting a white sticker on its head, now forever maimed by our screwdriver, proving that we've been inside…tampering.

    • The device hasn't proven especially difficult to enter, but small deterrents like hidden and tamper-evident screws never sit well with us.

  9. OnePlus One Teardown: step 9, image 1 of 3 OnePlus One Teardown: step 9, image 2 of 3 OnePlus One Teardown: step 9, image 3 of 3
    • We pull off an interior cover to access the battery connector. If our calculations are correct, the OnePlus One's battery is about to be subtracted.

    • Our spudger performs the necessary arithmetic, and the 3.8 V, 3100 mAh LiPo battery is ours (and yours) to inspect.

    • It fares well when compared to its 2800 mAh (Galaxy S5) and 2600 mAh (HTC One M8) rivals.

    • For those of us who don't read Chinese, this battery sports a maximum charging voltage of 4.35 V, and the following warnings and cautions (paraphrased):

    • Only use with approved chargers

    • Keep ventilated while charging

    • Do not tear down, short circuit, or puncture

    • Removing the motherboard requires disconnecting several connectors.

    • Being as careful as we possibly could be, we use an iFixit Tech Knife (more commonly known as a K-nife) to detach the rocker buttons from the side of the panel assembly.

    • As much as we love using knives to cut into devices, we heavily advise against it in most cases.

  10. OnePlus One Teardown: step 11, image 1 of 2 OnePlus One Teardown: step 11, image 2 of 2
    • Finally, with all the connectors out of the way, the motherboard is—

    • Drat and double drat! There's one last antenna connector on the back of this motherboard.

    • Luckily, we disconnect it faster than you can add 1+1.

  11. OnePlus One Teardown: step 12, image 1 of 3 OnePlus One Teardown: step 12, image 2 of 3 OnePlus One Teardown: step 12, image 3 of 3
    • Both the front-facing and rear-facing cameras are designed by Sunny Optical Technology.

    • The rear-facing camera is labeled P13N05A, while the front-facing camera is identified as P5V35A.

    • We also encountered camera modules designed by the optimistically-named Sunny Optical Technology in the Project Tango teardown.

    • According to the details on the OnePlus One specifications page, the 13 megapixel rear-facing camera features a Sony Exmor IMX 214 CMOS image sensor.

  12. OnePlus One Teardown: step 13, image 1 of 1
    • E pluribus unum. Here are the many chips that make up the One:

    • Samsung K3QF7F70DM-QGCF 3 GB LPDDR3 RAM; Qualcomm Snapdragon 801 likely layered beneath

    • Qualcomm WCD9320 Audio Codec

    • AGD2 2402 WX9DR (likely gyroscope)

    • Qualcomm PM8941 and PM8841 Power Management ICs Quick Charge 2.0 capable

    • 8407 CEH 05KTJ

    • B02419

    • P0911 3193

  13. OnePlus One Teardown: step 14, image 1 of 1
    • We've quickly run out of snappy Latin catchphrases—but chips? Not even close! The backside of the board contains:

    • Toshiba THGBMBG9D8KBAIG eMMC 5.0 64 GB Onboard Storage

    • Skyworks SKY77629-21 Power Amplifier Module

    • Qualcomm WCN3680 802.11ac/FM/BT 4.0 Combo Chip

    • Qualcomm WTR1625L RF Transceiver

    • Skyworks SKY85709 WLAN Front-End Module

    • Synaptics S3508A Touchscreen Controller

  14. OnePlus One Teardown: step 15, image 1 of 2 OnePlus One Teardown: step 15, image 2 of 2
    • We shift our focus to the front panel assembly.

    • Six screws (two of them hidden under more rubber plugs) and a flick of a spudger later, we've got the speaker assembly enclosure out.

    • The OnePlus One features a set of Yamaha stereo speakers that connect to the motherboard via spring contacts.

    • In the bottom center of the speaker assembly enclosure, we find a sticker that changes colors when orcs are near. It also acts as a water damage indicator.

  15. OnePlus One Teardown: step 16, image 1 of 3 OnePlus One Teardown: step 16, image 2 of 3 OnePlus One Teardown: step 16, image 3 of 3
    • Peeling up the USB port is easy enough, but it appears to be trapped under a slot in the midframe.

    • Touché! It's not trapped at all! What we thought was a wall was in fact a strip of tape—peel that away, and we're home free.

  16. OnePlus One Teardown: step 17, image 1 of 3 OnePlus One Teardown: step 17, image 2 of 3 OnePlus One Teardown: step 17, image 3 of 3
    • Oh no, this little cable offshoot is threaded under the midframe. We'll never get the daughterboard out—wait just a minute. Never mind.

    • In another exciting plot twist, this mysteriously chipped cable pops right out of its frame crevice.

    • This One has more plot twists than Star Wars has family secrets.

  17. OnePlus One Teardown: step 18, image 1 of 3 OnePlus One Teardown: step 18, image 2 of 3 OnePlus One Teardown: step 18, image 3 of 3
    • The daughterboard is finally freeeeee as a daughterbirrrd, now.

    • This daughterboard is the permanent home of various components, including the vibrator and primary microphone.

    • Along the bottom of the daughterboard are three LEDs for the front panel assembly capacitive buttons. The LEDs fit into the light guides at the base of the display.

    • With the display assembly stripped down to the midframe, it's time to test out a common repair: screen replacement!

    • After some heat and a bit of prying with an opening pick, we separate the display assembly from the midframe.

    • It's not a fun job, but it's certainly easier than another One we opened up on our teardown table.

    • The midframe bears the designation PC+GF, indicating it was made of polycarbonate infused with glass fibers.

    • We're a bit disappointed — we can't file it away and light it on fire, like we've done in the past. Sadness.

  18. OnePlus One Teardown: step 21, image 1 of 2 OnePlus One Teardown: step 21, image 2 of 2
    • OnePlus One Repairability Score: 5 out of 10 (10 is easiest to repair).

    • No proprietary screws and only one screw head type decreases cost of tools for repairs.

    • Fairly modular components will allow for less expensive replacement parts.

    • Slight adhesive used on the battery and several cables.

    • With its connector trapped under a plastic panel and several screws, the battery is more of a chore to replace than necessary.

    • The LCD and digitizer glass are fused together and must be replaced as a single part, and they require heat to remove from the midframe.


Hey guys, nice teardown. I'm guessing you probably already gave out your spare invites to your fellow workmates or friends but if you haven't I'd be eternally grateful for one.

Are you kidding me with this?

abdulalbasith -

Haha some ppl really can't hold there s**t together

yossi Grosskopf -

I bought 2 OPOs (sold one to a client, kept the other), both over a month ago, and have not received any invites. The invites I bought were $ 23.00 and $ 9.00, respectively, but now they seem to be in VERY short supply, and are going for bigger bucks. Not sure what's up with that!

PJ Blank -

Thank you. I was really waiting for this. OnePlus said they made the battery unremoveable to make the phone thinner, because they don't have to cover up the cables underneath.

That being said, do you think it's possible we will see a battery hack kit appearing on eBay? One that has a battery connector extender that extends to connector pins in the battery compartment and then a matching battery that can just be popped out?
