The first reason is the cost of the camera. Huawei mobile phones use German Leica cameras, and the cost of patented technology alone is very high.
The second reason is the workmanship cost. The workmanship of Huawei's flagship mobile phone is more refined and high-quality than that of Honor mobile phones.
The third reason is the cost of technology patents. Some black technologies are only used in Huawei phones, such as mobile phone waterproof technology, wireless fast charging technology, etc. These technologies are not available on Honor phones.
The fourth reason is the cost of the screen. The cost of a good mobile phone screen is relatively high. The screen of Huawei mobile phones is better than that of Honor mobile phones.
