Samsung's Galaxy S10 may be all display on the surface, but what's underneath that enigmatic exterior? Quite a lot, apparently. iFixit has torn down the entire S10 family, and it's evident that Samsung has stuffed each phone to the gills. Most notably, cooling is everywhere. The back cover, display and wireless charging pads are blanketed in graphite, while the touted copper heat pipe is much larger -- it's closer to that in the Galaxy Note 9 than the cooling you saw in the S9. The iFixit team believes this might be necessary to keep the reverse wireless charging from cooking the phone.
