Performance
Under the hood, the Lenovo Vibe X3 c78 is equipped with a Mediatek MT6753 chipset built on a 28 nm architecture. It houses an octa-core Cortex-A53 CPU clocked at 1.3 GHz, paired with a Mali-T720MP3 GPU. While not groundbreaking, this combination promised smooth day-to-day performance handling essentials with relative ease, although it might struggle with more intense, modern tasks or gaming sessions. The phone ships with Android 5.1 Lollipop, a version that was contemporary at the launch but shows its age today.
