Performance
The HTC Titan ran on the Microsoft Windows Phone 7.5 Mango OS, a distinctive choice compared to the Android and iOS alternatives available. Powered by a Qualcomm MSM8255 Snapdragon S2 chipset with a 1.5 GHz Scorpion CPU and Adreno 205 GPU, the performance was generally smooth, particularly for the applications and tasks typical for its era. While it only came with 512MB RAM, the efficient nature of Windows Phone 7.5 generally kept things running without significant lag. The absence of a memory card slot meant users had to make do with 16GB of internal storage, suitable for moderate data users but limiting for those with extensive media libraries.
