We're in Australia with iFixit tearing down the brand new iPhone X, which came out here about an hour ago (it was released at 8 AM local time). We bought the phone, hopped in a car, and raced across town to Circuitwise, an electronics manufacturer in suburban Sydney.

From there, we tossed it into an x-ray machine made by Creative Electron to see what's in the guts of the thing. As it turns out, there's a hell of a lot of battery; everything else has shrunk significantly. The teardown is really just getting underway, so expect more details later, but first impressions: This iPhone really is quite a departure from old models.
