Teardowns of Samsung’s Galaxy Note 20 have found that some have graphite cooling systems, while others have copper vapor chambers, with each cooling system “seemingly chosen at random.” iFixit said Monday it dismantled both the Note 20 5G and Note 20 5G Ultra, and didn’t find copper vapor-chamber cooling — but other teardowns have.
“To soak up all the heat from each phone’s octo-core processor, we expect to find a sprawling copper vapor chamber here — the kind Samsung was always quick to brag about in previous Galaxy Phones. But instead, we find a multi-layered graphite thermal pad,” iFixit said. “Stranger still, it seems some other Note 20 phones dohave copper heat pipes — but not our US-spec model.”
