Performance
In terms of performance, the Cat B15 runs on the Mediatek MT6577 chipset with a dual-core 1.0 GHz Cortex-A9 CPU and a PowerVR SGX531 GPU. It comes with 512 MB of RAM and 4 GB of internal storage, expandable via a dedicated microSDHC slot. Running Android 4.1 Jelly Bean, the phone offers a functional, albeit dated, user experience. The hardware combination supports basic smartphone tasks like calls, texts, and light browsing, but may struggle with more demanding applications due to its limited processing power and memory.
