The team at iFixit first noticed a large battery powering the new Nexus 7. 

We love seeing what's inside interesting new pieces of technology with photographic appeal. The folks at iFixit tear down the latest gadgets to reveal what's inside, offering a unique perspective of what makes the tech tick. Their latest project has been the second iteration of Google's popular Nexus 7 tablet, a device we were excited to learn about last week.

After literally cracking open the device (the rear cover suffered in the process), iFixit began to carefully pick apart the new Nexus 7, revealing: 

  • drastic change in body type. The second generation is thinner, narrower, and taller than its chunkier predecessor, and lacks texture on the rear panel.
  • Seals cover two of the screws in the Nexus 7 — one on each of the main boards — so replacing either board will likely void your warranty. 
  • The battery is rated at 3.8 V, 15 Wh, and 3950 mAh. Despite the 4326 mAh battery of the original Nexus 7, this new generation boasts an extra hour of battery life. 
  • A bevy of hardware:
    • Qualcomm APQ8064 Snapdragon S4 Pro Quad-Core CPU (includes the Adreno 320 GPU)
    • Elpida J4216EFBG 512 MB DDR3L SDRAM (four ICs for 2 GB total)
    •   Analogix ANX7808 SlimPort Transmitter
    •   Texas Instruments BQ51013B Inductive Charging Controller
    •   Qualcomm Atheros WCN3660 WLAN a/b/g/n, Bluetooth 4.0, and FM Radio Module
    •   SK Hynix H26M51003EQR 16 GB eMMC NAND Flash
    •   Qualcomm PM8921 Quick Charge Battery Management IC

The new Nexus 7 offers the same 1.2-megapixel front-facing camera as the first iteration of the device, but also adds a 5-megapixel primary camera.

iFixit coincidentally rated the new Nexus 7 a repairability score of 7 out of 10. You can see the entire teardown on iFixit's website.
