Display Comparison
Both phones feature similar contrast ratios at 1356:1, suggesting comparable image depth. However, the Moto G9 Plus boasts a measured peak brightness of 522 nits, offering a significantly more visible display in outdoor conditions. While the Y51’s display specifications aren’t provided, it’s reasonable to assume a lower peak brightness given its lower price point. This difference impacts usability under direct sunlight, favoring the G9 Plus.
Camera Comparison
Both devices are listed as having Photo/Video capabilities, but detailed camera specifications are absent. However, given the G9 Plus’s positioning and the general trend in smartphone cameras, it likely features a more capable primary sensor and potentially better image processing algorithms. The Y51, being a more budget-focused device, likely prioritizes affordability over advanced camera features. Without specific sensor details, it’s difficult to make a definitive judgment, but the G9 Plus’s overall hardware suggests a superior camera experience.
Performance
The core difference lies in the chipsets: the vivo Y51 utilizes the Qualcomm Snapdragon 665 (11nm), while the Moto G9 Plus features the Snapdragon 730G (8nm). The 730G’s Kryo 470 Gold cores, clocked at 2.2 GHz, outperform the Y51’s 2.0 GHz Kryo 260 Gold cores. The 8nm process node of the 730G also contributes to better thermal efficiency, reducing the likelihood of performance throttling during sustained workloads. This translates to smoother multitasking and a more responsive gaming experience on the Moto G9 Plus.
Battery Life
Both the vivo Y51 and Motorola Moto G9 Plus achieve an endurance rating of 136 hours, indicating similar overall battery life under typical usage. However, the Moto G9 Plus’s 30W wired charging capability is a significant advantage. This allows for much faster replenishment of the battery, reducing downtime compared to the Y51’s 18W charging. While both will last a full day for average users, the G9 Plus offers convenience with its quicker charging speeds.
Buying Guide
Buy the vivo Y51 (2020, September) if you prioritize a simple, reliable device for basic tasks like calling, texting, and light social media use, and are on a very tight budget. Buy the Motorola Moto G9 Plus if you value faster performance for gaming and multitasking, appreciate quicker charging speeds, and want a phone that feels more future-proof.
Frequently Asked Questions
❓ Does the Snapdragon 730G in the Moto G9 Plus handle demanding games like PUBG Mobile smoothly?
Yes, the Snapdragon 730G is capable of running PUBG Mobile at medium to high settings with stable frame rates. Its Adreno 618 GPU provides sufficient graphical power for a smooth gaming experience, unlike the Snapdragon 665 which may struggle with higher settings.
❓ How long does it realistically take to fully charge the Motorola Moto G9 Plus with the 30W charger?
With the included 30W charger, the Motorola Moto G9 Plus can typically charge from 0% to 100% in approximately 65-75 minutes. This is significantly faster than the vivo Y51’s 18W charging, which would likely take over 2 hours for a full charge.
❓ Is the camera on the Moto G9 Plus significantly better than the Y51 for low-light photography?
While specific camera specs are limited, the Moto G9 Plus likely performs better in low-light conditions due to its more powerful image signal processor (ISP) within the Snapdragon 730G. This allows for better noise reduction and detail preservation in challenging lighting scenarios.
