Performance
The Lenovo A660 operates on Android 4.0.4 Ice Cream Sandwich, running a Mediatek MT6577 chipset. Its dual-core 1.0 GHz Cortex-A9 CPU paired with a PowerVR SGX531u GPU offers basic performance, suitable for typical smartphone activities like browsing, messaging, and light app usage. With 512MB of RAM and 4GB of internal storage—which can be expanded via a dedicated microSDHC slot that includes an 8GB card—multitasking and storage space are very limited, reflective of the era's technological constraints.
