Display Comparison
Both devices feature displays with a 1356:1 contrast ratio, suggesting similar visual pop. However, the Moto G9 Plus boasts a measured peak brightness of 522 nits, offering better visibility in direct sunlight compared to the Y51s, which lacks published brightness data. While both are likely IPS LCD panels, the G9 Plus’s higher brightness is a tangible advantage for outdoor use. Bezels are comparable, and neither device is expected to offer high refresh rates at this price point.
Camera Comparison
Both phones offer 'Photo / Video' capabilities, but specifics are limited. Without detailed sensor information, it’s difficult to make a definitive judgment. However, the market segment suggests both will rely on primary sensors around the 48MP mark. The Moto G9 Plus’s image processing is generally tuned for natural colors, while vivo often employs more vibrant, saturated profiles. The presence of a 2MP macro camera on both devices is largely a marketing tactic, offering limited practical benefit due to the low resolution and lack of optical image stabilization (OIS).
Performance
The Motorola Moto G9 Plus’s Snapdragon 730G (8nm) and the vivo Y51s’s Exynos 880 (8nm) are both 8nm chips, but their CPU architectures differ. The G9 Plus utilizes 2x2.2 GHz Kryo 470 Gold cores alongside 6x1.8 GHz Kryo 470 Silver cores, while the Y51s features 2x2.0 GHz Cortex-A77 cores and 6x1.8 GHz Cortex-A55 cores. The Cortex-A77 in the Y51s is generally considered slightly more powerful per clock cycle, but the Snapdragon 730G’s optimized software and GPU often translate to a smoother overall experience, particularly in gaming. Thermal management is a key consideration; the Snapdragon 730G is known for its efficiency, potentially leading to less throttling during extended gaming sessions.
Battery Life
The Motorola Moto G9 Plus boasts an endurance rating of 136 hours, indicating excellent battery life. While the Y51s’s battery capacity is unknown, the G9 Plus’s 30W wired charging is a significant advantage over the Y51s’s 18W charging. This translates to substantially faster top-up times, reducing downtime. A full charge on the G9 Plus will likely take under 90 minutes, while the Y51s could require over two hours.
Buying Guide
Buy the vivo Y51s if you prioritize a potentially slightly faster CPU for basic multitasking and are comfortable with slower charging speeds. Buy the Motorola Moto G9 Plus if you value faster charging, consistent performance, and a proven track record for battery endurance. The G9 Plus is ideal for users who heavily rely on their phone throughout the day and need quick top-ups.
Frequently Asked Questions
❓ Does the Exynos 880 in the vivo Y51s tend to overheat during prolonged gaming sessions?
While the Exynos 880 is an 8nm chip, it's known to be less efficient than the Snapdragon 730G. This means it's more likely to throttle performance under sustained load, potentially leading to frame drops and a warmer device during extended gaming. The Moto G9 Plus is generally better suited for longer gaming sessions.
❓ Is the 2MP macro camera on either phone actually useful for taking detailed close-up photos?
Unfortunately, the 2MP macro cameras on both the vivo Y51s and Motorola Moto G9 Plus are largely marketing features. The low resolution and lack of autofocus result in images that are often soft and lack detail. They are unlikely to provide a significant improvement over using the main camera in standard photo mode.
❓ Can the Motorola Moto G9 Plus reliably maintain 60fps in popular games like PUBG Mobile?
The Snapdragon 730G in the Moto G9 Plus is capable of running PUBG Mobile at 60fps with medium to high graphics settings. However, achieving a consistently smooth experience will depend on the specific device configuration and background processes. Expect some occasional frame drops during intense action sequences.
❓ How long does it realistically take to fully charge the Motorola Moto G9 Plus with the included 30W charger?
The Motorola Moto G9 Plus, with its 30W charging, can typically go from 0% to 100% in approximately 75-90 minutes. This is a significant advantage over the vivo Y51s’s 18W charging, which could take over two hours for a full charge.
