Multitasking performance on a Samsung phone is primarily governed by the power of the processor (System-on-Chip) and the amount of RAM available to hold running applications. The fastest Samsung devices leverage the latest flagship chipsets—specifically the Snapdragon 8 Elite or its equivalent high-end Exynos version—which feature dedicated, high-speed cores for handling multiple complex tasks simultaneously. The superior optimization in Samsung’s One UI 7/8 software further enhances this by efficiently managing background processes and memory allocation.
Two key hardware specifications define elite multitasking capability: 12GB of LPDDR5X RAM and UFS 4.0 internal storage. The large RAM capacity allows the phone to run demanding apps and keep numerous applications, such as video editors and games, open in the background without forcing a restart. Furthermore, UFS 4.0 storage provides ultra-fast data read/write speeds, enabling the device to process data quickly when launching heavy applications or switching between them instantly.
Samsung’s foldable phones, the Galaxy Z Fold series, also introduce a physical advantage for multitasking with features like Multi-Active Window. This capability allows users to divide the large screen into up to three active sections, viewing, editing, and interacting with three different applications simultaneously. The combination of industry-leading hardware and productivity-focused software makes these 10 phones fastest for power users and professionals.
