Performance
Running on Android 9.0 (Pie), with potential upgrades to Android 11, the Xperia 1 is powered by the Qualcomm Snapdragon 855 chipset. This 7nm SoC, paired with an octa-core CPU configuration and Adreno 640 GPU, provides top-tier performance and efficient multitasking. With configurations offering 64GB or 128GB of UFS 2.1 internal storage and 6GB of RAM, the Xperia 1 is well-equipped to handle demanding applications and future updates, although only the dual-SIM model supports expandable storage via microSD.
