Performance
Running on Android 5.1 Lollipop with ZTE's nubia UI 3, the Blade X9 is powered by the Qualcomm Snapdragon 615 chipset, which was quite popular for budget and mid-range devices then. The octa-core CPU, split into four cores clocked at 1.5 GHz and another four at 1.0 GHz, allows smooth multitasking and satisfactory performance for everyday tasks. The Adreno 405 GPU handles graphics, making casual gaming feasible. However, with 2GB of RAM and 16GB of internal storage, the device might struggle with more demanding applications or multitasking between numerous apps.
