Which type of central processing unit (CPU) is commonly found in mobile phones?

The ARM Central Processing Unit (CPU) is commonly found in mobile phones due to its efficient power consumption and performance characteristics that are well-suited for battery-operated devices. ARM architecture is designed to maintain a balance between processing power and energy efficiency, making it ideal for mobile devices where battery life is crucial.

Manufacturers of mobile devices favor ARM CPUs because they can provide adequate processing power for applications while consuming less energy compared to x86 architecture (like Intel Core or AMD Ryzen), which is more common in desktops and laptops. As a result, nearly all smartphones and many tablets use ARM-based processors, enabling them to deliver more extended service on a single charge and supporting a wide range of mobile applications.

This focus on efficiency is what makes ARM the dominant architecture in the mobile sector, ensuring devices are not only powerful for everyday tasks but also optimized for longevity in performance on battery power.
