Credit: Robert Triggs / Android AuthorityMy thoughts on the state of USB-C and gadget fast charging are well documented by now; an interoperability nightmare that causes not just a headache for users but has also spun a web for manufacturers that few have successfully untangled. The problem is multifaceted: the overabundance of charging protocols (both proprietary and standardized universal) and battery health considerations make fast charging incredibly difficult to implement properly.After years of trying to match chargers and cables with gadgets, I’d given up on anyone building a project that can work with all this legacy mess. At least that’s what I thought until I spent a couple of weeks getting to know the new Xiaomi 17 Ultra.
