Edit Step 1 LG G Watch Teardown  ¶

Edit Step 1 LG G Watch Teardown  ¶ 

  • Tired of dull black-n-gray, we picked up a white an' goooollllld teardown unit with the following specs:

    • 1.65” IPS LCD

    • 400 mAh battery

    • Qualcomm® Snapdragon™ 400 processor with 1.2GHz CPU

    • 512 MB RAM / 4 GB Flash

    • 9 Axis (Accelerometer/Compass/Gyro)

    • Bluetooth 4.0

Edit Step 2  ¶

  • Here it is, in all its marbelous white gold glory.

  • Speaking of which: If your smartwatch committed a crime and was in a police lineup, could you identify it?

Edit Step 3  ¶

Edit Step 3  ¶ 

  • Everyone knows this watch as the G Watch (we're pretty sure because this watch is for upper-case Gs only—no lower-case Gs need apply), but the official model is LG-W100.

    • We agree that "G Watch" is a much catchier name.

    • More importantly, we spot some T5 screws that will allow for easy, adhesive-free access. Thanks, LG! Things could have been a lot worse for this little guy.

    • We were pretty darn sure the G Watch was utterly buttonless—until we found this cute little paperclip-actuated reset switch on the back.

  • The only other feature in this slick square is the most important one: a microphone allowing you to basically be Dick Tracy anytime, anywhere.

Edit Step 4  ¶ 

Edit Step 4  ¶ 

  • The included charging dock is crazy easy to use. It even works one handed.

Edit Step 5  ¶

Edit Step 5  ¶ 

  • Every watch needs to have an exit strategy. Just like batteries, straps eventually wear out, and (just like batteries) should be user-replaceable.

  • The LG G Watch has a more traditional, but trickier, strap removal process than the Samsung Gear Live (and Gear 2). Instead of pulling a built-in pin, you'll need to compress the spring with a thumbnail, precision tweezers, or a handy Swiss Army Knife blade.

Edit Step 6  ¶

Edit Step 6  ¶ 

  • Alright, alright, back to those not-so-dastardly T5 Torx screws. Let's see what treasure they guard.

  • We remove the four screwy fasteners and use an opening pick to disengage a couple of retaining clips.

  • Presto-blamo—we're inside!

  • When we open these ring-box-like devices, it's almost like we're being proposed to: "Dearest iFixit, will you marry me?"

Edit Step 7  ¶

Edit Step 7  ¶ 

  • This watch splits apart very similarly to the Gear Live:

    • Rear half has the battery, vibrator, and some other fidgety doodads

    • Front half has the main board and display

  • First treasure extracted: a springy metal retaining clip that secures the battery. It also hosts a chunk of rubber that that connects the reset button to the microswitch on the motherboard.

  • Next victim: the vibrator. This particular unit connects via simple spring contacts, unlike the soldered-to-a-board-connected-to-the-main-board approach the Gear Live utilizes.

Edit Step 8  ¶

Edit Step 8  ¶ 

  • Time to leave the nest, battery. Tiny strips of double-sided tape hold it securely, but offer little resistance to our spudger. We likey.

  • Our battery recommends we refer to user's guide. Let's see what's inside:

    • "Do not attempt to repair or modify or remanufacture the product. It is equipped with an internal rechargeable battery, which should be replaced only by LG or an authorized LG repair center."

    • Okay sure. Just gonna leave this right here. If you can't open it, you don't own it.

Edit Step 9  ¶

Edit Step 9  ¶ 

  • A small rubber gasket runs around the perimeter of the LG G, earning it the advertised IP67 rating.

    • This means the device is both dust tight, and can withstand immersion in 1 meter of water for up to 30 minutes.

    • Don't take it SCUBA diving, but feel free to leave it on while you wash the dishes, or maybe even take a shower—if you're feeling daring.

Edit Step 10  ¶

Edit Step 10  ¶ 

  • Thanks to the spring contacts between the two halves of the LG G, we need only dispatch two connectors: display data and digitizer cables. They're easily released with our handy spudger.

  • Just as easily, the motherboard is popped up out of the hefty metal bezel securing the display assembly.

Edit Step 11  ¶

Edit Step 11  ¶ 

  • Chips up front:

    • SK Hynix H9TU32A4GDMC 512 MB DRAM—the Qualcomm APQ8026 System on Chip is layered beneath

    • Qualcomm PM8226 power management IC

    • InvenSense MPU-6515 6-axis accelerometer + gyroscope

    • InvenSense INMP441 Microphone

    • 2407 DSH 12EDF

Edit Step 12  ¶

Edit Step 12  ¶ 

  • Not much back here:

    • Synaptics S3402B ClearPad 3400 series touchscreen controller

    • Broadcom BCM20715 Bluetooth 4.0 controller

Edit Step 13  ¶ 

Edit Step 13  ¶ 

  • We're gonna need some heat to separate the display glass from the metal bezel, so it looks like it's time to drop an iOpener on our G-unit.

Edit Step 14  ¶

Edit Step 14  ¶ 

  • After three solid minutes of watching the video in the previous step, and congratulating each other on its fabulous humor (while the iOpener did its thing), the display adhesive is soft enough to relinquish its grip.

  • A little gentle pressure from the back of the LCD gives our opening pick just the edge it needs to sneak in and separate the display from the watch bezel.

Edit Step 15  ¶

Edit Step 15  ¶ 

  • LG G Watch Repairability Score: 9 out of 10 (10 is easiest to repair)

    • Screws and spring contacts mean the rear case is super easy to remove.

    • The battery is held in with a single Phillips screw and minimal adhesive, making replacement easy.

    • Not the easiest watch band to remove, but an old standard that shouldn't pose much of a threat to band-replacers.

    • Clean design with few fragile cables and connectors means a more robust, repair-ready device.

    • A fused display assembly, glued into the front of the device, makes screen replacement a little difficult and costly.
