Performance
Under the hood, the HTC One A9s is powered by the Mediatek MT6755 Helio P10 chipset with an octa-core CPU consisting of four 1.8 GHz Cortex-A53 cores for performance and four 1.0 GHz Cortex-A53 cores for efficiency. Paired with the Mali-T860MP2 GPU, the device is capable of handling standard apps and basic multitasking fairly smoothly. It was available in configurations of 16GB storage with 2GB RAM or 32GB storage with 3GB RAM, both expandable via a dedicated microSDXC slot, which is a significant advantage for users needing more storage.
