August 24: Note20 + Note20 Ultra Teardown
Note20 + Note20 Ultra Teardowns
If there’s one thing we’ve come to expect from Galaxy Note teardowns, it’s vapor-chamber cooling. And that’s exactly what we didn’t find in the Note 20—either one of them. Just to be sure, we dismantled both the US-spec Note 20 5G and the Note20 5G Ultra at the same time.

Instead of big copper vapor chambers (or, “Water-Carbon Cooling Systems,” as Samsung trumpeted in past marketing), we found … graphite. A whole lot of it. Stranger still, we’ve already seen a couple other teardowns of these phones pop up on YouTube*, one of which had … a copper vapor chamber. So what gives? Is Samsung A/B testing a revised cooling system? Short of a teardown, how can you ever know which version you got? Both are tried-and-tested solutions, but we’ve never seen both deployed in the same model seemingly at random.

Notable differences between the Note 20's 📝

  • So far as we know, Samsung hasn't hinted at different charging capabilities in the Note 20 line—but an X-ray of both Note 20s shows two different wireless charging coil configurations. The Note 20 Ultra inherits the same double-coil configuration we first saw in its cousin, the S20 Ultra.

  • Battery-wise, the Note 20 and Ultra weigh in at 16.69 and 17.46 watt-hours, respectively. Both are (unsurprisingly) larger than the 15.04 Wh pack in the iPhone 11 Pro Max, while trailing the 19.30 Wh monster in the S20 Ultra.

  • Both Note 20 devices earn a 3/10 on our repairability scale—but the regular Note 20 gets a slight edge, thanks to its polycarbonate (plastic) back cover.
