Inside the LG G Watch and Samsung Gear Live smartwatches

The iFixit team have their hands on an LG G Watch and a Samsung Gear Live smartwatch, and the teardown reveals some similarity between the two devices — an inside dominated by a Li-Ion battery, and a design that's surprisingly easy to open.

For small devices, the LG G Watch and a Samsung Gear are surprisingly easy to pop open to repair, earning them a repairability score of 9 and 8 out of 10 respectively (where 10 is the easiest to repair). There are no thick goopy adhesives or tamper-resistant screws to deal with — although if you're thinking of delving inside you must be prepared to handle some tiny screws.

Inside the smartwatches are the following:

LG G Watch:

  • SK Hynix H9TU32A4GDMC 512 MB DRAM with the Qualcomm APQ8026 System on Chip layered beneath
  • Qualcomm PM8226 power management IC
  • InvenSense M651 6-axis accelerometer + gyroscope
  • Synaptics S3402B ClearPad 3400 series touchscreen controller
  • Broadcom BCM20715 Bluetooth 4.0 controller
  • 3.8 V, 400 mAh battery

Samsung Gear Live:

  • MAX77836 — likely micro-USB interface controller and Li+ battery charger
  • STMicroelectronics STM32F401 Cortex M4 microcontroller
  • Samsung KMF5X0005A-A210 512 MB DRAM package with the Qualcomm APQ8026 System on Chip layered beneath
  • Qualcom PM8226 power management IC
  • InvenSense MP92M 9-axis Gyro + Accelerometer + Compass
  • Cypress Semiconductor CYTMA54 touchscreen controller
  • 3.8 V, 300 mAh battery

What struck me from the teardowns was how much empty space there was inside the smartwatches. I'm so used to seeing smartphones internals which are densely packed, so the empty space inside these devices came as a bit of a shock.

That said, this space does allow for more to be crammed into them, and looking at the circuit boards there seems to be plenty of scope there to pack the components tighter.
