Samsung's new silicon-carbon batteries in Galaxy Z Fold 8 won't last as long
Samsung has shifted to silicon-carbon batteries in the Galaxy Z Fold 8 series; however, the lifespan of these batteries has decreased to approximately 1,200 charging cycles from around 2,000 cycles seen in previous models. This change reflects the inherent limitations of silicon-carbon technology, which allows for improvements in battery capacity but compromises longevity. While the Z Fold 8's new battery technology still surpasses competitors like Google and Apple in performance, the reduction in longevity raises concerns about long-term usability for consumers.
