On top of the whole RF Block there are 13 WiFi/BT/GPS/Main antennas and two other antenna modules responsible for NFC communication and Wireless Charging capabilities. The Huawei Pura 70 Pro HBN-AL00 Cellular Phone/Handset has a total cost of$478.89. This is about 20% more than the average Cellular Phone/Handset. The Octa-Core HiSilicon Kirin 9010 was made in 7nm process node and cost $74.28. The main frame was made of Aluminum and Plastic using extensive machining process. It cost $13.25 which is almost 35% off all non-electronics parts.
