The intrepid folks over at iFixit finally got their mitts on the Galaxy S7 and did what they do best: take stuff apart. However, this teardown wasn’t simply about peeling away the layers and peeking at the phone’s specs.

In particular, the site took a close look at the device’s thermal spreader, which Samsung talked about during the Galaxy S7’s announcement; the company described the tiny heat pipe as “air conditioning for your phone.” So is it all it’s cracked up to be?

“This year Samsung pulled an Apple, claiming to invent the phone-based heat pipe,” iFixit said. “Not only are they not the first, but this heat pipe is minuscule—and not even in the neighborhood of the “liquid cooling” hype we’ve been hearing about.”

iFixit delves much deeper into the device, taking it apart piece by piece and providing an extensive look at the components that are inside. If you’re at all interested in how much work goes into a single phone, the post is a must-see. One big thing to note: because Samsung waterproofed the device, the S7’s display was glued to the “midframe,” which was moved deeper into the phone. This makes the screen incredibly difficult to replace.

Overall, the phone was given a “Repairability Score” of 3 out of 10. While iFixit praised the fact that components can be replaced independently, replacing the USB port and display is pretty much out of the question without ruining other parts of the phone.
