vivo iQOO 3 5G

  • Significantly faster 55W charging
  • Potentially lower price point
  • Snapdragon 865 offers strong performance

  • Less refined software experience
  • Camera likely less versatile than S20+

Samsung Galaxy S20+ 5G

  • Versatile camera system with strong video
  • Polished Samsung One UI software
  • Wireless and reverse wireless charging

  • Exynos 990 (global version) can throttle under load
  • Slower 25W wired charging

Display Comparison

The iQOO 3 5G boasts a peak brightness of 848 nits, a respectable figure, but the S20+ likely surpasses this (Samsung typically achieves higher peak brightness). Both utilize 7nm+ fabrication, but the display technologies differ. While specifics on the S20+ panel aren’t provided, Samsung’s displays are known for color accuracy. The iQOO 3’s ‘infinite’ contrast ratio is a marketing term, but suggests a strong VA-type panel. The S20+ likely has a higher refresh rate option, a key advantage for smoother scrolling and gaming, though this isn't specified in the provided data.

Camera Comparison

The provided data only indicates ‘Photo / Video’ capabilities for both. Without sensor size, aperture, or megapixel counts, a detailed comparison is difficult. However, Samsung’s Galaxy S20+ is renowned for its camera versatility, particularly its video recording capabilities. The iQOO 3 likely prioritizes still photography, but lacks the brand recognition and software optimization of Samsung’s camera system. The presence of a 2MP macro camera on either device is largely irrelevant; image quality from such sensors is typically poor.

Performance

Both phones, in their respective configurations, can be equipped with the Qualcomm Snapdragon 865 5G (7nm+). However, the global S20+ shipped with the Exynos 990 (also 7nm+). The Snapdragon 865, as found in the US S20+ and the iQOO 3, generally offers superior sustained performance and thermal management compared to the Exynos 990. The iQOO 3’s CPU configuration (1x2.84 GHz Cortex-A77, 3x2.42 GHz Cortex-A77, 4x1.80 GHz Cortex-A55) is identical to the US Snapdragon S20+, suggesting similar raw CPU power. The Exynos 990’s CPU (2x2.73 GHz Mongoose M5, 2x2.50 GHz Cortex-A76, 4x2.0 GHz Cortex-A55) has a different architecture, but the real-world performance difference is often minimal. The iQOO 3’s focus on cooling likely allows it to maintain peak performance for longer.

Battery Life

The iQOO 3 5G boasts an endurance rating of 118 hours, a solid result. Crucially, it supports 55W wired charging, capable of reaching 50% charge in just 15 minutes. The S20+ offers a slower 25W wired charging with PD3.0, 15W wireless charging (Qi), and 4.5W reverse wireless charging. While the S20+ offers wireless charging convenience, the iQOO 3’s significantly faster wired charging is a major advantage for users who prioritize quick top-ups. The actual battery capacity (mAh) isn’t provided, but the iQOO 3’s charging speed effectively mitigates any potential capacity disadvantage.

Buying Guide

Buy the vivo iQOO 3 5G if you need uncompromising performance for gaming and demanding tasks, and prioritize incredibly fast charging. You’ll benefit from a more aggressive price point. Buy the Samsung Galaxy S20+ 5G if you prefer a more polished software experience, a versatile camera system with strong video capabilities, and integration with the Samsung ecosystem, and are willing to pay a premium.

Frequently Asked Questions

❓ Does the Exynos 990 in the global S20+ overheat during extended gaming sessions?
The Exynos 990 is known to be less thermally efficient than the Snapdragon 865. This can lead to throttling – a reduction in performance – during prolonged gaming or other demanding tasks. While Samsung implemented cooling solutions, the iQOO 3, with its Snapdragon 865 and likely more aggressive cooling, is generally better suited for sustained high performance.
❓ Is the 55W charging on the iQOO 3 5G compatible with Power Delivery (PD) chargers?
While the S20+ supports PD3.0 with its 25W charging, the iQOO 3 utilizes its own proprietary 55W charging standard. You'll need to use the included charger or a compatible vivo SuperCharge charger to achieve the full 55W charging speed. Standard PD chargers will still charge the device, but at a slower rate.
❓ How does the software experience differ between the iQOO 3 5G and the Galaxy S20+ 5G?
The Galaxy S20+ runs Samsung's One UI, known for its feature-richness, customization options, and generally polished user experience. The iQOO 3 runs vivo's Funtouch OS, which has improved over time but is often considered less refined and may include more pre-installed bloatware. Samsung also provides longer software support.
