iPhone China Sales Down 30% in Q1 2019

Apple’s iPhone China sales are down 30% in Q1 2019. Huawei continues to dominate, capturing 34% of China’s smartphone market.
Apple’s performance in China is concerning, given that the worst quarter for iPhone shipments is usually Q2 or Q3, not Q1 when new devices are still fresh. Apple has acted to cut iPhone retail prices, which has largely relieved the pressure from its channel partners.
I wonder how much of iPhone sales in China were impacted by Chinese companies encouraging employees to boycott Apple in favor of Huawei.
