Huawei's first 5G phone would have power, would need a large heatsink

Few companies have designed their own 5G wireless chips, let alone chips and handsets that will use them. That's why a new DigiTimes report on China Huawei is raising red flags this morning: Huawei's first 5G phone will pull a lot more energy than 4G phones and will apparently require a copper cooling module from first quality to dissipate heat. Rotating CEO, Eric Xu, has confirmed that the company's 5G chips will consume 2.5 times the power of current 4G chips. Although Xu suggests that it's a compromise for better performance than existing chip offerings, it means that Huawei's first 5G phones will require larger batteries and more power. atypical cooling solutions. Xu said more research and development will be needed to improve the heat sink and energy saving technologies of the 5G chip.

To solve the problem of heat dissipation of its first 5G phone, Huawei will use Auras Technology. The modules are supposed to be 0.4mm thick copper sheets, a fairly expensive component previously used in high end slim laptops. Although Auras has been using the modules in some smartphones for two years, much cheaper graphite is more commonly used for smartphone cooling.

Auras is expected to begin volume production of the copper cooling modules in September, well before the release of Huawei's phone. , which should now be shipped in June 2019. It has been months since competing 5G phones should ship with Qualcomm's Snapdragon X50 modems, but probably before 5G devices using Intel XMM 8000 5G modems.

The sizes and shapes of the early 5G mobile devices remain unclear, no company having shown finalized 5G phone case. While Qualcomm recently announced incredibly small 5G components, Intel has only shown great 5G device prototypes. Samsung is working on an Exynos 5G chipset for several 5G devices but has not yet revealed what its 5G smartphones will look like.
