J'ai copié ci-dessous les étapes que vous pouvez retrouvez sur ce lien avec une vidéo en bonus : NExus 5 Teardown

Step 1 — Nexus 5 Teardown 

• 
  The Nexus 5 is the first phone to ship with the latest version of Android's OS, KitKat. It may not be coated in chocolate, but it has plenty of tasty features:
  
  
  
  
  • 
    4.95" full HD 1920x1080 display at 445ppi
    
    
  • 
    Quad-core, 2.26 GHz Snapdragon 800 processor and 450 MHz Adreno 330 GPU
    
    
  • 
    2 GB RAM
    
    
  • 
    8 MP/1080p rear camera with optical image stabilization, and 1.3 MP front-facing camera
    
    
  • 
    4G/LTE wireless support, 802.11 a/b/g/n/ac (2.4GHz and 5GHz) dual-band Wi-Fi, NFC, Bluetooth 4.0, and wireless charging
    
    
  • 
    16 GB or 32 GB built-in memory
    
    
  • 
    Android 4.4 KitKat
    
    
  
  

EditStep 2 

• 
  Sounds of joy emanate from the teardown factory as we find this Nexus is held together by…plastic clips!
  
  
  
  
  • 
    These clips are plenty stubborn, but nothing like the headache that a glued panel would be.
    
    
  
  
  
  
• 
  Agent P.O.T. (plastic opening tool) is deployed to handle this noble mission.
  
  

EditStep 3 

• 
  We may have cheered too soon—either someone spilled some chocolate syrup, or that's adhesive securing the bottom of the case.
  
  
  
  
  • 
    
    Finding glue in your gadget is as much fun as finding chewed gum on your shoe.
    
    
  
  
  
  
• 
  Luckily this bit of foam adhesive is no match for a few swipes of a plastic opening pick. Our poor fixer souls have seen much worse recently.
  
  
• 
  With the adhesive out of the way, we get our first peek inside this delicious new device.
  
  

EditStep 4 

• 
  Before taking another bite, we pause to chew over the back case:
  
  
  
  
  • 
    We find conveniently labeled antennas for the Wi-Fi, MIMO, and GPS. It's not quite instructions, but hey, we'll take what we can get.
    
    
  • 
    The NFC and wireless charging cables' spring contacts aren't so nicely identified, but are present and accounted for.
    
    
  • 
    The vibrator is held in place with only a small amount of adhesive. That means an easy repair, should your phone lose its ability to shake it up.
    
    
  
  
  
  
• 
  How many licks screws does it take to get to the center of a Nexus 5?
  
  
  
  
  • 
    No matter the number, our Pro Tech Screwdriver Set is up to the task.
    
    
  
  

2 EditStep 5 

• 
  Google gives us the Goldilocks of glue: It's just enough to hold the battery in place, but not too much—the battery can still be removed with minimal prying and virtually no bending.
  
  
• 
  Non-LG manufacturers, take note! We don't want none of your "that ain't possible" funny business when it comes to using glue in devices.
  
  

3 EditStep 6 

• 
  LG's 3.8 V, 2300 mAh battery offers a slight jump in capacity over last year's Nexus 4.
  
  
• 
  Google boasts that this pack will keep you sugar-high for 17 hours of talk time, 300 hours of standby, or 7 hours of LTE web browsing.
  
  
• 
  We're pretty sure this warning icon indicates that it's unsafe to let pets smaller than this battery anywhere near it.
  
  

EditStep 7 

• 
  Time to break us off a piece of this KitKat phone!
  
  
• 
  The speaker pops out with minimal fuss; it's only secured by few screws and no cables. This is the Nexus standard single speaker, despite the dual grilles.
  
  
  
  
  • 
    
    No, this Nexus is not preparing for a BBQ—the second grille is for the microphone. Don't worry; we'll get there soon.
    
    
  
  

EditStep 8 

• 
  We free the Oompa-Loompa-colored daughterboard, and she's got more goodies than the Easter Bunny:
  
  
  
  
  • 
    Microphone
    
    
  • 
    RGB Indicator LED
    
    
  • 
    Micro-USB port
    
    
  • 
    Speaker spring contacts
    
    
  • 
    Antenna spring contacts
    
    
  
  

EditStep 9 

• 
  Less tasty, but more powerful than a Pixy Stick, ourspudger makes motherboard removal easier than taking candy from a baby.
  
  
• 
  We quickly spudge away the wireless charging control and NFC board. LG built this little board into an EMI shield assembly that pops in right over the motherboard.
  
  
  
  
  • 
    
    This shape reminds us a little of thishelpful KitKat map…
    
    
  
  
  
  
• 
  
  NFC is the tech behind Google Wallet—one of the Nexus devices' most loved features and one often blocked by carriers. Last month, the rumor mill speculated that the Nexus 5 would feature a Broadcom NFC controller that could eliminate carriers' ability to wallet-block customers.
  
  
  
  
  • 
    Lo and behold: the Broadcom BCM20793M NFC controller.
    
    
  
  

EditStep 10 

• 
  That's some scrumptious silicon! Feast your eyes on these ICs:
  
  
  
  
  • 
    Sandisk SDIN8DE4 16 GB NAND flash
    
    
  • 
    Qualcomm WTR1605LLTE/HSPA+/CDMA2K/TDSCDMA/EDGE/GPS transceiver
    
    
  • 
    Qualcomm PM8841 power management IC
    
    
  • 
    Broadcom BCM4339 5G Wi-Fi combo chip with integrated power and low-noise amplifiers (the updated version of the BCM4335).
    
    
  • 
    Avago RFI335
    
    
  • 
    InvenSense MPU-6515 six-axis (gyro + accelerometer) MEMS MotionTracking device
    
    
  • 
    Asahi Kasei AK8963 3-axis electronic compass
    
    
  
  

1 EditStep 11 

• 
  SK Hynix H9CKNNNBPTMRLR-NTM 2 GB LPDDR3-1600 RAM
  
  
  
  
  • 
    The Quad-core, 2.26 GHz Snapdragon 800 SoC is layered beneath the RAM
    
    
  
  
  
  
• 
  Qualcomm WCD9320 audio codec
  
  
• 
  Analogix ANX7808 SlimPort transmitter
  
  
• 
  Qualcomm PM8941 power management IC
  
  
• 
  Texas Instruments BQ24192 I2C controlled 4.5 A USB/adapter charger
  
  
• 
  Avago ACPM-7600
  
  

2 EditStep 12 

• 
  Out next is the 8MP rear-facing camera.
  
  
• 
  
  Google has taken some criticism for the less-than-impressive image capture in last year's candy-powered devices. This year they've added Optical Image Stabilization (OIS), but we've only heard tepid reviews so far.
  
  
  
  
  • 
    The Nexus 5's OIS is powered by an InvenSenseIDG-2020 dual axis gyroscope.
    
    
  
  

EditStep 13 

• 
  We pop out the last of the bite-sized morsels in the Nexus 5:
  
  
  
  
  • 
    Earpiece speaker
    
    
  • 
    Headphone jack
    
    
  • 
    1.3 MP front-facing camera.
    
    
  
  
  
  
• 
  What a treat! These components were modular and only lightly adhered, seasoned just to our repair tastes.
  
  

2 EditStep 14 

• 
  Unfortunately, our hopes come crashing down like a blood sugar crash after a candy binge: the front panel is one fused flustercluck.
  
  
• 
  While we saw this in the Nexus 4, we had hoped the LG/Google team could learn the error of their ways.
  
  
• 
  Alas, the front frame, LCD, and glass are doomed to a single shared death sometime down the road toCandy Land.
  
  
  
  
  • 
    
    Imagine if one cavity meant losing allyour teeth... Talk about a hard pill to swallow.
    
    
  
  
  
  
• 
  Tucked in at the base of the display, a Synaptics S3350B IC provides touchscreen control.

EditStep 15 

• 
  Nexus 5 Repairability Score: 8 out of 10 (10 is easiest to repair).
  
  
• 
  Very modular design allows independent replacement of several wear-prone components—like the headphone jack and speakers.
  
  
• 
  Only very mild adhesive holds the battery in place, making it fairly easy to safely remove and replace.
  
  
• 
  Standardized screws (ten identical #00 Phillips) simplify repairs and reassembly.
  
  
• 
  The back cover is held in place with plastic clips. Sturdy and rather difficult to remove, but easier than glue.
  
  
• 
  The glass and LCD are fused to the display frame. Fixing broken glass will be either expensive or very difficult.
