vivo Y51s
- Sleek design (based on brand aesthetic)
- Exynos 880 offers decent performance for everyday tasks
- Potentially lower price point (depending on region)
- Slower 18W charging
- Potential for thermal throttling under heavy load
- Limited information on display quality
Xiaomi Poco X3 NFC
- Faster Snapdragon 732G processor
- 33W fast charging for quick top-ups
- Excellent battery endurance (125h rating)
- Design may be less premium than the Y51s (subjective)
- Camera details are limited
- Software experience can be heavily customized
Display Comparison
Both devices share a nominal contrast ratio of 1299:1, suggesting similar visual pop. However, detailed display specs like peak brightness and panel type are missing for the Y51s. The Poco X3 NFC’s display, while not exceptional, is known for its 120Hz refresh rate, offering smoother scrolling and animations – a feature absent in the Y51s. This difference is particularly noticeable during gaming and fast-paced content consumption.
Camera Comparison
Both phones feature 'Photo / Video' capabilities, but lack specific details. Without sensor size or aperture information, a direct comparison is difficult. However, the market positioning of the Poco X3 NFC suggests a more versatile camera system. The Y51s, often targeted at a more budget-conscious consumer, likely prioritizes cost savings over advanced camera features. The presence of a 2MP macro camera on many phones in this segment is often a marketing tactic rather than a significant photographic advantage.
Performance
The core difference lies in the chipsets. The Poco X3 NFC’s Snapdragon 732G, built on an 8nm process, features Kryo 470 Gold cores clocked at 2.3 GHz, offering a slight clock speed advantage over the Y51s’ Exynos 880 (2.0 GHz Cortex-A77). While both are 8nm chips, Qualcomm’s Snapdragon typically demonstrates better sustained performance and thermal management. The Y51s’ Exynos 880, while capable, is known to exhibit more throttling under prolonged load. The Poco X3 NFC’s availability with 6GB or 8GB of RAM further enhances its multitasking capabilities.
Battery Life
The Poco X3 NFC boasts a 125-hour endurance rating, indicating excellent battery life. Crucially, it supports 33W wired charging, achieving 62% charge in 30 minutes and 100% in 65 minutes. The vivo Y51s, with only 18W charging, will take considerably longer to fully replenish its battery. While the Y51s’ battery capacity isn’t specified, the faster charging of the Poco X3 NFC provides a significant convenience advantage, minimizing downtime and maximizing usability.
Buying Guide
Buy the vivo Y51s if you prioritize a sleek design and are comfortable with a slower charging experience. It’s a solid all-rounder for everyday tasks. Buy the Xiaomi Poco X3 NFC if you’re a mobile gamer, value fast charging, and need a phone that can keep up with demanding applications. Its robust chipset and larger battery provide a noticeable advantage in performance-intensive scenarios.
Frequently Asked Questions
❓ Does the Exynos 880 in the vivo Y51s overheat during prolonged gaming sessions?
The Exynos 880 is known to exhibit thermal throttling under sustained load. While it can handle casual gaming, demanding titles may experience frame drops and reduced performance after extended play. The Poco X3 NFC’s Snapdragon 732G generally manages heat more effectively.
❓ Is the 2MP macro camera on either phone actually useful for taking detailed close-up photos?
Typically, 2MP macro cameras on phones in this price range offer limited detail and image quality. They are often included as a marketing feature rather than a genuinely useful photographic tool. Expect soft images and limited dynamic range.
❓ Can the Poco X3 NFC reliably maintain 60fps in popular games like PUBG Mobile?
The Snapdragon 732G in the Poco X3 NFC is capable of running PUBG Mobile at 60fps with medium to high graphics settings. However, sustained performance may vary depending on the game settings and ambient temperature. The Y51s may struggle to maintain a consistent 60fps in demanding scenarios.
❓ How much faster is the 33W charging on the Poco X3 NFC compared to the 18W charging on the vivo Y51s?
The Poco X3 NFC’s 33W charging can fully charge the phone in approximately 65 minutes, while the Y51s’ 18W charging will likely take well over 2 hours. This difference is significant for users who frequently need to quickly top up their battery.
