OnePlus 13 vs S21 Pro

OnePlus 13 512GB wins on battery and charging: 6000mAh with 15:28h active use and 100W wired charging (50% in 13 min) versus vivo S21 Pro’s 5500mAh and 90W wired charging. Gamers and heavy users needing all-day endurance and ultra-fast top-ups should choose the OnePlus 13, as its 100W wired and 50W wireless charging outpace the vivo’s 90W. Photographers seeking versatile optics should pick the vivo S21 Pro, as its 50MP wide with AF is simpler than the OnePlus’s triple setup with periscope 3x zoom and ultrawide, but the vivo’s lower price and smoother software experience suit those prioritizing daily camera reliability over zoom flexibility. In UAE at AED 2999 vs AED 2250, vivo S21 Pro is better because it delivers 90W charging and 5500mAh battery at 25% lower cost. In India at ₹79999 vs ₹49999, vivo S21 Pro wins on value because it offers near-identical charging speed and 96% of the battery capacity for ₹30000 less.
