Huawei, Honor, Oppo, and Vivo have collaborated to standardize a unified charging protocol in China. The four Chinse smartphone makers came together in an event at the UFCS Industry Development Conference held in Shenzhen on May 22 to sign a new agreement around the Universal Fast Charging Standard (UFCS) 2.0 protocol.
For those unaware, the UFCS charging was first introduced by Huawei, Oppo, Vivo, and Xiaomi in 2021. It served as a base for framing the centralized mobile fast charging standards for these brands.
UFCS Version 2.0 Upgrades
Version 2.0 of UFCS introduces some notable technical updates over the first generation. Chief among them is support for 40W unauthenticated power delivery. This means devices can charge at higher speeds without needing proprietary handshakes between brand-specific adapters and cables.
The protocol also introduces a reverse charging feature, allowing supported devices to charge others, regardless of brand.
According to the companies, UFCS 2.0 also makes PowerChange—active adapter power adjustment—a required feature. In practice, this means chargers will automatically detect and adjust output based on the connected device, regardless of its brand. It’s a feature meant to improve safety and efficiency, while reducing the friction that often comes with third-party charging accessories.
The four brands coming together for a unified charging standard is a win for users. Fast charging has become an expected feature on modern smartphones, but it remains fragmented.
Each brand historically pushed its own proprietary solutions, leading to a mess of incompatible standards and excess chargers for consumers. UFCS, in theory, reduces that fragmentation, at least within this alliance.
Whether this protocol will see adoption beyond China or by global competitors like Samsung or Apple remains unclear. But as long as companies keep agreeing to siloed standards, users will remain dependent on which ecosystem they buy into.
