Qualcomm chips are produced in the United States, and it is the largest mobile phone chip manufacturer in the world. Snapdragon 600, 800 and APQ series that we are familiar with are all chips that sell well in Qualcomm at present. Fortunately, he has strong compatibility with games and is very good at dealing with web browsing. Of course, when Android is popular now, its power control ability is also relatively good, and its overall performance is slightly stronger for Samsung's hummingbird Galaxy chip. The second is Qualcomm or Samsung. Of course, Qualcomm is too powerful. A few years ago, NVIDIA's mobile phone chips were also good.
Of course, Huawei's Hisilicon chip is also good, but its compatibility and game performance need to be improved, but I can't be too responsible. After all, the most important thing for Huawei is not to research chips.
I hope my answer is helpful to you.
