Performance
Under the hood, the Zenfone 3 is powered by the Qualcomm Snapdragon 625 chipset, featuring an octa-core Cortex-A53 CPU clocked at 2.0 GHz and an Adreno 506 GPU. This combination ensures a smooth performance for everyday tasks and moderate gaming. It originally shipped with Android 6.0.1 (Marshmallow), but users can upgrade to Android 7.0 (Nougat) with ZenUI 3. Users can opt for models with either 32GB of storage paired with 3GB RAM or 64GB with 4GB RAM, both using eMMC 5.1 technology. The microSDXC slot shares its space with the secondary SIM, a common trade-off in hybrid dual-SIM setups.
