It’s Mobile World Congress this week, which implies getting into the wild world of idea telephones. Usually, these are versatile show gadgets that won’t ever see the sunshine of day, however this 12 months OnePlus has the “OnePlus 11 Concept” cellphone. This has a liquid cooling system referred to as “Active CryoFlux.” We will attempt to decipher this factor, however our first blazing crimson flag is that OnePlus doesn’t go into a lot element.
It’s price noting that OnePlus has made a number of idea telephones, which have by no means actually affected the corporate’s client merchandise. One cellphone put electrochromic glass in entrance of the digital camera lenses, rendering them invisible after they weren’t getting used. Another cellphone would change colours. Neither function ever made it right into a client cellphone.
OnePlus’ press launch says the system options “a piezoelectric ceramic micropump at its core, linked to pipelines sandwiched between an higher and decrease diaphragm. The micropump takes up an space lower than 0.2 cm², enabling cooling liquid to flow into across the pipelines with out considerably growing OnePlus 11 Concept’s weight and thickness.”

If this screenshot from the advertising video is not purely fabricated, there’s a skinny cooling sticker with some liquid in it that will get slapped to the again of the cellphone and sandwiched underneath the glass.

The blue liquid supposedly goes into and across the digital camera bump, but it surely’s not essentially cooling something.

This is OnePlus’ image of the “micropump.” I assume it is linked to the blue piping, however OnePlus’ photos do not make that clear.
Those fancy blue lights on the again appear to be the cooling system and are not simply there for seems. The press launch says, “The clear again delivers a mesmerizing view of the Active CryoFlux pipelines at work,” which additionally occur to be lit up. OnePlus additionally says, “Active CryoFlux liquid flows across the digital camera like a halo,” so all the pieces blue is cooling liquid, based on OnePlus.
As for the precise outcomes of this method, OnePlus says, “In laboratory exams, Active CryoFlux has been proven to carry down a cellphone’s temperature throughout gaming by as much as 2.1°C, enhancing a recreation’s body price by 3-4 levels, or by 1.6°C throughout charging, shaving 30-45 [seconds] from the charging time.” Those numbers usually are not significantly spectacular. Phones throttle fairly rapidly because of warmth, and largely cope with “cooling” by going slower. OnePlus’ press launch quote uniquely measures body price in “levels”—I’m fairly certain they imply “frames”—and 3-4 frames is usually the margin of error in a benchmark. Phones are very warmth constrained and often cope with their passive cooling options by slowing down so they do not overheat. Adequate cooling would make a cellphone loads quicker, particularly for extended use, like gaming.
The liquid doesn’t appear to go wherever, which might clarify why OnePlus’ cooling outcomes are so meager. Water cooling in PCs works by attaching a water block to a scorching factor, like your CPU or GPU, heating that liquid, after which shifting it to one thing that can cool it down, often a radiator with some followers behind it. Is that precise cooling loop replicated right here? The cellphone has no discernible technique to cool the liquid off as soon as it heats different than simply passive cooling. There’s no fan, as we have seen on some telephones, and no radiator or different cooling equipment.
It looks like there is a small quantity of equal-temperature liquid simply sloshing round in there, and OnePlus hopes it should dissipate warmth because it strikes throughout the again of the cellphone. It in all probability does not assist that the cooling system is sandwiched contained in the cellphone by a glass panel, which is an insulator. OnePlus additionally does not explicitly say that the liquid cooling is meaningfully linked to the SoC through a water block. It’s not clear what parts it’s cooling.
A “glass unibody” can not probably be right. You can see the image there and that is a largely regular glass cellphone again.

Finally, some marketer determined to explain the cellphone’s design with “Glass Unibody,” which feels like an absolute nightmare idea for cellphone sturdiness. There appears to be nothing to this declare aside from advertising: There’s nonetheless a steel body across the cellphone, and OnePlus’ image of the “unibody” simply appears to be a standard rear glass panel. An precise “unibody” would contain the again and body of the cellphone being made out of a single piece, with the person electronics mounting to that piece contained in the cellphone. Thankfully OnePlus didn’t make use of a really expert glass blower or something, and there does not appear to be rather more glass right here than in a standard OnePlus 11.
