Display Comparison
The Realme 9 Pro+ boasts an 'Infinite' (nominal) contrast ratio, a marketing term that doesn't provide concrete details about panel quality. Neither device specifies peak brightness or panel technology (OLED vs LCD), but given the price point, OLED is likely on both. The lack of detailed display specs makes a direct comparison difficult, but the Realme's advertised contrast ratio suggests a focus on vibrant visuals. Without further data, it's difficult to assess color accuracy or viewing angles.
Camera Comparison
Context data is limited regarding camera capabilities. Both phones likely feature multi-camera systems, but specifics are missing. The absence of sensor size or aperture information prevents a meaningful comparison. The Realme 9 Pro+ may benefit from MediaTek's Imagiq 790 ISP, potentially offering enhanced image processing. However, without knowing the main sensor resolution or pixel size, it's impossible to determine which phone captures better photos or videos. We can assume both will include standard features like HDR and night mode.
Performance
The core difference lies in the chipsets. The vivo Y31 Pro’s Dimensity 7300, fabricated on a 4nm process, is inherently more power-efficient than the Realme 9 Pro+'s Dimensity 920 (6nm). While the 920 features a slightly different CPU core configuration (2x A78 vs 4x A78 on the 7300), the architectural advantage of the 4nm node is significant. This translates to less heat generation under sustained load, potentially reducing throttling during gaming. The Y31 Pro's CPU configuration suggests a stronger focus on multi-core performance, while the 920 may excel in burst performance. Both devices utilize an octa-core setup with the same Cortex-A55 efficiency cores, but the 7300's superior process node gives it an edge.
Battery Life
The Realme 9 Pro+ claims a full charge in 44 minutes with its 60W charging, utilizing PD3.0. The vivo Y31 Pro charges at 44W and reaches 50% in 40 minutes, implying a full charge will take longer. However, the Dimensity 7300's efficiency could offset this difference in charging speed with improved overall battery life. The Realme 9 Pro+ boasts an endurance rating of 117 hours, a significant figure suggesting excellent power management. The Y31 Pro's battery capacity is unknown, but its more efficient chipset could deliver comparable real-world usage.
Buying Guide
Buy the vivo Y31 Pro if you need a phone that will maintain peak performance during extended gaming sessions or heavy multitasking, and value long-term efficiency. Buy the Realme 9 Pro+ if you prioritize the absolute fastest charging speeds and are less concerned about sustained performance under heavy load. The 9 Pro+ is also a better choice if battery endurance is your primary concern, given its 117-hour rating.
Frequently Asked Questions
❓ Will the Dimensity 920 in the Realme 9 Pro+ overheat during prolonged gaming sessions?
The 6nm Dimensity 920 is a capable chipset, but its larger process node compared to the Y31 Pro's Dimensity 7300 means it's more prone to thermal throttling during extended gaming. While it will likely handle most games at high settings, expect some performance dips over time.
❓ Does the 44W charging on the vivo Y31 Pro feel significantly slower than the 60W on the Realme 9 Pro+ in real-world use?
While 60W is faster on paper, the difference in charging time may not be drastic. The Y31 Pro reaches 50% in 40 minutes, suggesting a reasonably quick initial charge. The efficiency of the Dimensity 7300 could also contribute to faster overall charging times by reducing heat buildup.
❓ Is the Realme 9 Pro+'s 117-hour endurance rating realistic for typical usage?
Endurance ratings are based on specific usage patterns. 117 hours suggests excellent standby time and efficient power management. However, heavy gaming, video streaming, or constant use of mobile data will significantly reduce battery life. Expect real-world usage to be lower, but still competitive.
