Chinese cell phone brands face increasing competition at home and abroad, especially from the dominance of the foreign brand iPhone. The competitive pressure on these brands has intensified against the backdrop of U.S. sanctions on Chinese mobile chips. This study examines the marketing strategies of leading Chinese brands such as Huawei, Xiaomi, and OPPO to cope with this competitive landscape. The study examines how these brands have successfully entered and expanded into overseas markets through case studies and data analysis. The findings show that these brands have adopted strategies such as catering to specific consumer needs, utilizing low prices to attract consumers with limited budgets, increasing brand awareness, and exploring new international markets. Notably, Huawei’s patriotic marketing strategy brings both benefits and risks, while OPPO’s use of brand partnerships is also a noteworthy marketing approach. The study concludes that while the iPhone maintains a stable market share and loyal fan base in China, Chinese brands must adopt a differentiation strategy to avoid direct competition with Apple. This requires focusing on unique value propositions, such as superior affordability, innovative features, or tailored marketing approaches, to secure a more diverse and resilient market position.
