Performance
Under the hood, this smartphone is powered by a Qualcomm MSM8996 Snapdragon 821 chipset, a high-performance processor at the time of its release. The quad-core CPU, comprising two 2.35 GHz Kryo and two 1.6 GHz Kryo cores, along with an Adreno 530 GPU, ensures smooth operation across various applications, making it adept at handling multitasking and gaming needs. The Cool S1 is available in two configurations: one with 64GB of internal storage paired with 4GB of RAM, and a more robust version with 128GB of storage coupled with 6GB of RAM. However, the absence of a microSD card slot may be a drawback for users needing additional storage expansion.
