Nexus 7 Teardown

iFixit has taken apart Google's second generation Nexus 7 tablet, which uncovers, among other components, the hardware that supports wireless charging.

Let us remind you of the specs of the 2013 Nexus 7:

- 1.5 GHz Qualcomm Snapdragon Pro S4 processor
- 7-inch 1920x1200 IPS LCD screen
- 2 GB of RAM
- Adreno 320 GPU
- 5 MP rear-facing camera
- 1.2 MP front-facing camera
- Android 4.3 Jelly Bean

Comparing the second generation Nexus 7 to the first, the latest device is thinner, narrower, and taller than its beefier predecessor, and lacks texture on the rear panel.

Other changes include the addition of a rear-facing camera, and an upgrade to stereo sound. There are now two speakers (DN17128L000) at the base, and one up top.

Under the hood there is a huge battery (3.8 V, 15 Wh, and 3950 mAh) along with an inductive charging coil, used for wireless charging. Despite the 4326 mAh battery of the original Nexus 7, this new generation boasts an extra hour of battery life.
