Performance
Under the hood, the Nexus 5 is powered by the Qualcomm Snapdragon 800 chipset, featuring a quad-core 2.3 GHz Krait 400 CPU and Adreno 330 GPU. This combination delivers smooth and responsive performance, capable of handling multitasking and demanding applications. The device initially shipped with Android 4.4 (KitKat), but it is upgradable to Android 6.0 (Marshmallow), benefiting from Google's regular software updates. It lacks a card slot for expandable storage, offering 16GB or 32GB internal storage paired with 2GB RAM, which was fairly standard for its time.
