    Verdict

    The Xiaomi 12 (8GB + 128GB) is a compact flagship smartphone featuring the powerful Snapdragon® 8 Gen 1 processor, a 6.28-inch 120Hz AMOLED display with Dolby Vision and HDR10+, and a versatile triple camera system (50MP main with OIS, 13MP ultrawide, 5MP telemacro). Key pros include its high performance, excellent in-hand feel due to its slim and lightweight design, stunning and color-accurate screen, very fast 67W wired and 50W wireless charging support, and high-quality Harman Kardon tuned stereo speakers. The main cons are its disappointing battery life which struggles under heavy use, the tendency of the processor to overheat during strenuous tasks like prolonged gaming or 4K/8K video recording, the lack of an official IP rating for water and dust resistance, no expandable storage via microSD, and the presence of some bloatware in the MIUI interface.
