Performance
Under the hood, the Lenovo S660 is powered by a MediaTek MT6582M chipset, featuring a quad-core 1.3 GHz Cortex-A7 CPU and a Mali-400MP2 GPU. Paired with 1GB of RAM, the phone runs on Android 4.2 Jelly Bean, an operating system that is now dated but in line with the era's standards. This combination makes the S660 capable of handling everyday tasks such as web browsing, social media applications, and light gaming, although users may encounter lags with more demanding applications or multitasking.
