(Yicai Global) Dec. 29 -- Due to the growing maturity of the Chinese smartphone market, several Chinese mobile phone brands have reportedly slashed supply order volumes, placing considerable pressure on component and parts suppliers. The country's three major phone makers -- Huawei, Vivo and Oppo -- have decided to cut order volumes, by as much as 10 percent in some cases, financial news outlet STCN reported today. 

Chinese smartphone supply chain businesses are confronted with increasing earnings pressures. The six A-share listed suppliers saw 10 percent to 18 percent slumps in their share prices this month, STCN reported. Some brokerage firms have dumped these shares.

Furthermore, Apple Inc.[NASDAQ:AAPL] and Samsung Electronics Co. [KRX:005930] have also trimmed orders for Chinese suppliers -- in the former's case by 40 percent., some reports claimed, despite two supplier firms, Changsha-based Lens Technology Co. [SHE:300433] and Anjie Technology Co. [SHE:002635] headquartered in Suzhou, denied it. However, a source at a brokerage firm said the tech giant has already lowered sales forecasts.

Global shipment of Chinese smartphones dropped 9.7 percent to 448 million units during the first 11 months of this year, with a 20.7 percent decline recorded last month, statistics show.
