Performance
Powered by the Qualcomm Snapdragon 810 chipset, coupled with an octa-core processor (4x1.5 GHz Cortex-A53 & 4x2.0 GHz Cortex-A57) and Adreno 430 GPU, the Xperia Z5 Premium offers solid performance for its time. With 3GB of RAM and 32GB of internal storage expandable via microSDXC, the device handles multitasking and gaming well, although it was somewhat overshadowed by concerns regarding the Snapdragon 810's heat management issues. It originally shipped with Android 5.1.1 (Lollipop) and was upgradable to Android 7.0 (Nougat), providing an adequately modern user experience for a few years post-launch.
