Performance
Under the hood, the Vivo V21s is powered by the MediaTek Dimensity 800U chipset, fabricated on a 7nm process, which competes well against many other mid-range options. The octa-core processor comprises two Cortex-A76 cores clocked at 2.4 GHz and six Cortex-A55 cores at 2.0 GHz, delivering balanced performance for multi-tasking and general use. The Mali-G57 MC3 GPU provides adequate graphics performance for most mobile games. The device runs Android 12 while incorporating Vivo's Funtouch 12 interface, which brings several customization options along with an intuitive user experience.
