The majority of modern smartphones are powered by system-on-a-chip (SoC) technology, which integrates multiple components, including the CPU, GPU, and memory, into a single chip. This integration enhances efficiency and performance while reducing size and power consumption. Leading manufacturers, like Qualcomm with its Snapdragon series and Apple with its A-series chips, utilize SoCs to deliver advanced capabilities such as high-speed internet connectivity, sophisticated graphics rendering, and AI-driven features.
