Android phones with Si-C batteries charge slower

The author argues that while silicon-carbon (Si-C) battery technology successfully delivers much higher smartphone capacity and longevity, it has coincided with a disappointing slowdown in per-mAh charging speeds. Manufacturers appear to be throttling charging power to prevent electrode expansion, degradation, and high temperatures, prioritizing battery lifespan over fast top-ups. Consequently, users may end up spending more time waiting for larger batteries to fully charge unless they frequently find themselves away from an outlet. Open article →
