Under the hood, the Vivo Y21s is powered by the MediaTek MT6769V/CU Helio G80 chipset, built on a 12 nm process. Its octa-core CPU comprises two Cortex-A75 cores clocked at 2.0 GHz and six Cortex-A55 cores at 1.8 GHz, coupled with a Mali-G52 MC2 GPU. This hardware configuration ensures smooth everyday performance and handles multitasking effectively, though it may show limitations under demanding gaming conditions. The phone runs Android 11 with Vivo’s Funtouch 11.1 UI, which offers a user-friendly experience with additional customization options and features.
