Let’s take a look at how this new thermal solution takes smartphone cooling to the next level.

As smartphones get more advanced with faster and graphics-churning processors, there’s always one hurdle that it always faces: heat. For the longest time, manufacturers have come up with various ways on how to effectively cool smartphones, especially with varying results. Overheating has been a major side effect of smartphones, which can limit its performance and of course can also be life-threatening.

Unlike computers that use big, heavy fans to cool down components, the same cannot be done on a smartphone due to its size and smaller components. Smartphones are normally cooled down through its design – think of the entire device as a heatsink that utilizes passive cooling as a way to direct heat away. It’s a tried and tested method and used by Apple’s iPhone line and even previous Huawei flagships. Samsung has introduced a form of water cooling with the Galaxy S7, where it used a form of liquid that absorbed heat and carried it away in a pipe. It was an effective solution that’s for sure, but cooling technology doesn’t stop there.

New trends at the moment now involve big-screen smartphones – but as these devices get bigger, so is the power needed to operate it. Big smartphones like the Huawei Mate 20 X require more processing power, which in turn would need better cooling systems if they want to operate to its full extent. Sure, you can always stick in a larger heatsink on the device, but that will make it heavier and bulkier. I’m sure you wouldn’t want to carry around a smartphone that weighs a kilogram.

It was one of the key challenges that were faced by smartphones like the iPhone XS Max and the Galaxy Note 9. Huawei’s latest big-screen device, the Mate 20 X, also faced this challenge but the company has already developed (and patented) a new technology that would make heating problems a thing of the past.

In comes graphene, a thin layer of granite that’s capable of handling high temperatures and it’s also proven to handle heat up to four times better than a normal aluminum alloy. Huawei and the University of Cambridge have already filed a patent where it said that they have developed a form of heat conduction based on functionalized graphene. This form of functionalized graphene has vastly improved thermal conductivity by almost 50 percent. The best part is that graphene’s manufacturing process is cost-effective and can be made in new industrial facilities that are more environmental-friendly. The best part? It weighs relatively less than other heat dissipation setups and this translates to a lighter smartphone.

In layman’s terms, Huawei has successfully created a new smartphone cooling solution that can handle the heat generated by its top-of-the-line SoC (System-on-a-chip). This also means that you can use your smartphones for intensive tasks without worry of overheating.

The Huawei Mate 20 X utilizes graphene film to keep it running cool. In fact, this is the first smartphone that features a liquid multi-dimensional cooling system that conducts the heat generated fast, away from the precious components. Since the processor is running cooler, there won’t be any throttling involved, so you’ll always get the full maximum power that the smartphone offers. Imagine playing Fortnite for hours on the Mate 20 X without worry of lagging or your device getting too hot – not to mention the 5,000 mAh battery that should last for hours.

Compare that to other smartphones which usually slows down the processor speed to control the heat, though the problem is that your experience will be noticeably laggy. Graphene helps the Huawei Mate 20 X to operate the processor for long periods without slowing down since heat is controlled to a minimum.

The graphene cooling solution on the Huawei Mate 20 X is just the tip of the iceberg. By now, you’re aware that the company has been investing in different technologies that we regularly see on each iteration of its flagship devices. We’ve also heard that graphene technology could soon be utilized on laptops as well, meaning we can see even more powerful yet lightweight devices in the future. There may something more that Huawei has under its sleeves, and we can’t wait to see what’s in store.
