Updated August 16: We’ve run some boosted tests to gauge the Galaxy Note nine’s power to sustain performance over the long booty.
Flagship phones in 2018 can easily handle graphically demanding games, but many of them run hot or simply can’t sustain their operation after several minutes of play.
The Milky way Note 9 has a feature designed to continue this flagship cool while delivering consequent speed: Samsung put a water-carbon cooling system in the device to go on it from breaking a sweat while you lot’re in the middle of an extended Fortnite session.
The advanced carbon-water cooling organisation, combined with a estrus sink that’southward iii times larger than the one inside the Note 8, helps with heat dissipation. Samsung says those improvements can prevent overheating by 21 percentage, just the visitor is emphasizing performance over temperatures.
Nosotros decided to put the Note 9’s cooling to the exam, and the results are mixed.
Sustained performance: Better than Milky way S9, simply not OnePlus 6

Milky way S9+
Galaxy Notation 9
The Milky way Note 9 does deliver better sustained speeds than the Galaxy S9+ when performing demanding tasks. We used the Antutu benchmark, which measures CPU, GPU memory and other aspects of operation and ran information technology vii consecutive times on both phones.
The Galaxy Notation nine delivered a higher max score of 271,018, and it never dropped below 222,000. On the same set of tests, the Galaxy S9+ dropped below 222,000 three times, once falling to 195,728. That’south a drop of 22 percentage from the S9+’s max score. The Note 9’s biggest drop was 15 per centum.
Even so, it’southward not all good news for Samsung’s h2o cooling. The OnePlus six on the same test started at 286,889 on Antutu and fell to but 272,531 on the 7th run. That’south a drop of only 5 percent. It’s worth noting that the OnePlus six we used has 8GB of RAM, or 2GB more than than the Galaxy Note ix.
On the other hand, the Note 9 did a better chore of keeping its absurd throughout this test than the OnePlus 6. The latter phone reached 100 degrees on the concluding run, while the Note 9 registered 93 degrees. In fact, the Note 9 stayed fairly cool throughout the test as the OnePlus 6 heated up.
The Galaxy S9+ also stayed fairly cool, though, starting at 97 degrees and settling at 94 degrees.
Indoor tests: Note nine is not the coolest
For the offset exam in our indoor lab, we ran CPU Loader, a CPU stress test; and 3DMark Slingshot Extreme Unlimited, a graphics performance test, simultaneously for 15 minutes, to put actress strain on each phone’s processor. At the end of the tests, both Notes registered 100 degrees Fahrenheit (every bit measured by our heat gun) on both the front and back of the devices; in that location was no noticeable temperature difference even in feel. We consider annihilation above 95 degrees uncomfortably warm.

Side by side, nosotros put the Note ix, Notation viii and iPhone X through two fifteen-minute AnTuTu benchmarks, recording the temperature every 5 minutes to get together an average. Hither, the Note viii actually proved the coolest, registering an boilerplate of 99.half dozen degrees. The Note 9 came in 2d, at 100.6 degrees, and the iPhone Ten ran the hottest, at 100.9 degrees. We measured the front and dorsum of the devices, which were comparable in temperature.
When we measured the final temperature of each phone, the running order changed again. This time, the Annotation ix was actually the hottest, striking 106 degrees; the Note viii topped out at 103 degrees, and the iPhone X hit 102 degrees.
Finally, we ran a few quick races of Asphalt ix: Legends with both Galaxy Note devices. Again, both handsets got as hot — about 90 degrees — though the Note ix felt ever so slightly cooler in the palm than the Annotation eight.
The torture exam: Exterior on a hot summer day
It was sunny and 88 degrees in New York when we visited Bryant Park to comport the outdoor portion of our overheating exam. We set the Galaxy Note 9, Notation 8 and iPhone Ten downward on a metal table that had been blistering underneath the sun, then ran 3D Marking’s Slingshot OpenGL ES three.i repeatedly until it produced a rut warning on each phone, recording the surface temperatures of the devices along the way.
The iPhone X was the first to show beads of sweat, slowing to an average of 3 frames per 2d after indelible almost half dozen minutes of 3DMark’s test. In comparing, the Note ix hovered at xiv fps, and the Note 8 delivered xi fps. The iPhone eventually became unresponsive at 14 minutes and thirty seconds, serving up a temperature alarm that prevented us from using the device at all until it sufficiently cooled downwardly. It measured 125 degrees on our oestrus gun at that signal.
Both Notes exhibited more than endurance, but interestingly, the Note 9’s cooling system didn’t seem to brand whatsoever noticeable difference. Both the Note ix and the Note eight called it quits at 130 degrees, and both lasted exactly 17:xxx earlier overheating notifications popped up. Bluntly, the consistency was pretty surprising, given that the Annotation 9 uses a water cooling organization with carbon fiber (the Notation 8 besides uses h2o cooling, just without carbon cobweb). That’due south supposed to make a divergence, just in our tests, it didn’t.
It’due south of import to note that, unlike the iPhone, Android’due south heat management doesn’t render the phone useless until information technology cools down. Rather, Android discreetly closes sure apps that are generating the near free energy while letting you use the residue of the device normally. Simply even when the two Annotation phones decided enough was enough, they were withal reasonably responsive. Meanwhile, the iPhone’due south animations slowed to a crawl minutes earlier it told us it needed to cool downwards. It was almost unusable.
The Galaxy Note 9 does evangelize bettter sustained performance than the Milky way S9+, which doesn’t benefit from the Note 9’s more avant-garde carbon water cooling. However, the Milky way S9 stayed just as cool. The OnePlus six ran hotter on our tests, only it actually managed to deliver improve performance over successive benchmark runs than the Notation ix.
Compared to the Annotation 8, which doesn’t take the Note 9’s water-carbon cooling feature or a massive thermal spreader, we saw no noticeable difference in temperature in any of our tests. Both phones got hot while running demanding apps, and both phones overheated at the same time in our outdoor torture test. Fifty-fifty in a more realistic scenario — playing a demanding game for an extended menses of time — the Note 9 felt just as warm as the Note 8.
So does the Note 9’southward water cooling work? Aye when information technology comes to delivering more consistent performance, but not necessarily in terms of keeping temps low.
