    Verdict

    The vivo iQOO Z9 (8GB + 256GB, Indian variant) is a performance-focused mid-range 5G smartphone featuring a MediaTek Dimensity 7200 4nm processor and a vibrant 6.67-inch, 120Hz AMOLED display with 1800 nits peak brightness. Key strengths include its excellent performance for the price, a reliable 50MP Sony IMX882 main camera with OIS and 4K video recording, and a long-lasting 5,000mAh battery with 44W FlashCharge support. However, drawbacks include the use of older UFS 2.2 storage, the absence of an ultrawide camera and 3.5mm headphone jack, an IP54 rating for only basic splash resistance, and the presence of some pre-installed bloatware in the Funtouch OS 14 interface.
