As iPhone technology evolves, so does the demand for reliable, high-performance replacement batteries. While Apple partners with elite global suppliers, China remains the epicenter of cutting-edge battery innovation and large-scale manufacturing. For repair businesses and distributors worldwide, sourcing from reputable Chinese manufacturers isn’t just an option—it’s a strategic advantage.

China’s Leading iPhone Battery Manufacturers in 2025

Based on production scale, technological innovation, and market reputation, these manufacturers dominate China’s battery ecosystem:

Sunwoda Electronic Co., Ltd.

A top-tier OEM for Apple and global brands, Sunwoda leverages AI-driven production lines and sustainable manufacturing. Their batteries power millions of devices worldwide.

EVE Energy Co., Ltd.

EVE leads in next-gen lithium technologies (e.g., silicon-anode prototypes). A favorite for high-cycle-life replacements, they’re pivotal to the third-party repair revolution.
