Feature Review Summary
Display & Design: Exceptional viewing with AMOLED, high brightness, and modern slim profile. Water-proofing capabilities make it more durable than most in the segment.
Performance & Software: Snapdragon 4 Gen 2 offers competent daily performance; extended storage and virtual RAM help multitasking. Rich AI features in Funtouch OS 15 cater to Gen‑Z productivity.
Battery & Charging: Standout endurance with 6000 mAh and industry‑leading fast charging performance.
Camera & Imaging: Versatile 50 MP primary camera with under‑water imaging and good selfie quality from 32 MP front cam. Depth sensor enhances portrait shots.
Connectivity: Broad 5G band support, Wi‑Fi 6, strong signal tools (SuperLink), USB‑C audio, stereo audio support.
Weaknesses: No headphone jack, and though day‑to‑day benchmarks are solid, it’s not suited for high‑end gaming. Vivo’s Funtouch OS still includes roughly more pre‑installed apps than some alternatives.
Ideal for: Buyers focused on display quality, durability (water/dust), huge battery with lightning-fast charging, and modern AI features—all under ₹24 K.
