SHENZHEN/SHANGHAI, May 9 - Huawei's latest high-end phone features more Chinese suppliers, including a new flash memory storage chip and an improved chip processor, a teardown analysis showed, pointing to the progress China is making towards technology self-sufficiency.
"While we cannot provide an exact percentage, we'd say the domestic component usage is high, and definitely higher than in the Mate 60," said Shahram Mokhtari, iFixit's lead teardown technician. The Pura 70 still contains a DRAM chip made by SK Hynix, iFixit and TechSearch found, but the NAND flash memory chip was likely packaged by Huawei's HiSilicon unit this time around and was made up of NAND dies each with a capacity of 1 terabit. This is comparable to products made by major flash memory producers such as SK Hynix, Kioxia and Micron
SK Hynix reiterated that it was "strictly complying with the relevant policies since the restrictions against Huawei were announced and has also suspended any transactions with the company since then".IFixit and TechSearch's analysis of the processor used by the Pura 70 Pro also suggests Huawei may have only made incremental improvements in its ability to produce an advanced chip with Chinese partners in the months since it launched the Mate 60 series.
