iPhone XS /XS Max have been Complained of Poor Signal
Qualcomm and apple have been fighting a patent war for a long time, and now the "war" could reach ordinary consumers. Previously, due to the patent war between qualcomm and apple, apple reluctantly abandoned qualcomm's base band to use Intel's base band, and the industry generally believed that Intel's base band was inferior to qualcomm's base band. All three of apple's phones this year use Intel's base band, and industry insiders worry that the iPhone XS may be inferior to other phones in terms of signal.
