This article originally appeared on ABACUS For the first time in almost two decades , Apple lowered its revenue outlook, attributing it to the weaker-than-expected sales in China. Chinese netizens know exactly what to blame: The ever-increasing price of iPhones. Apple CEO Tim Cook issued a letter to investors and spoke to CNBC , where he cited the economic slowdown in China as the primary reason behind the revenue decline. He also said the US-China trade war has greatly affected sales in the country. Netizens were far more blunt. “Is it really because of the slowed economic growth? Have you looked at your own products lately?” one of the top Weibo comments said . “Without any major technological breakthrough, iPhone prices have only gone up significantly.

Last year, Apple reduced its $79 battery replacement fee to $29 after the company was criticised for slowing down old iPhones with dying batteries.
