The latest quad-core chips are also supposed to have better battery backup, such as the Nvidia Tegra 3's fifth low-power companion core. Also, four-core CPUs tend to have better graphics processing units (GPUs) to match, such as the Qualcomm Snapdragon S4's Adreno 320.
Technically speaking, an Android phone, powered by quad-core processor, should have sharper screen resolution, smoother streaming of HD videos, and faster loading of apps along with faster opening of heavy graphic multiplayer games.
"The Android OS supports multi-threading and uses multiple CPU cores to deliver faster responsiveness and higher performance when the user is running multiple programmes at the same time. Multi-core processors also help deliver longer battery life by sharing workloads across multiple CPU cores and running each core at lower voltage and frequency. This results in significant battery life improvements," says NVIDIA.
Let us take a look at some of the best quad-core smartphones available in Indian market:
