Display Comparison
Both the Oppo F31 and Honor 9X Pro share a contrast ratio of 1319:1, suggesting similar visual depth. However, the Honor 9X Pro’s measured peak brightness of 517 nits provides a brighter viewing experience, particularly outdoors, compared to the Oppo F31 which lacks published brightness data. While both likely utilize IPS LCD panels, the lack of information regarding panel technology (like LTPO) on the F31 makes it difficult to assess its efficiency and potential for variable refresh rates. Bezels are not specified for either device, making a direct comparison impossible, but both fall into the mid-range category where minimizing bezels is a common design goal.
Camera Comparison
Both phones feature 'Photo / Video' capabilities, but detailed camera specifications are lacking. Without sensor size, aperture, or OIS information, a meaningful comparison is difficult. The absence of details suggests neither phone is positioned as a camera-centric device. Any 2MP macro lenses present on either device are likely to offer limited practical benefit due to their small sensor size and lack of optical image stabilization. Image processing style will be a key differentiator, but without sample images, it’s impossible to assess which phone produces more pleasing results.
Performance
The Oppo F31’s Mediatek Dimensity 6300 (6nm) and the Honor 9X Pro’s Kirin 810 (7nm) represent different approaches to mobile processing. The Dimensity 6300, built on a smaller 6nm node, generally offers improved power efficiency and transistor density compared to the 7nm Kirin 810. While the Kirin 810’s CPU configuration (2x2.27 GHz Cortex-A76 & 6x1.88 GHz Cortex-A55) is slightly faster on paper than the F31’s (2x2.4 GHz Cortex-A76 & 6x2.0 GHz Cortex-A55), the Dimensity 6300’s newer architecture and process node likely translate to better sustained performance and thermal management under load. The F31’s RAM configuration is unspecified, but assuming LPDDR4X or LPDDR5, it will be crucial for multitasking alongside the Dimensity 6300.
Battery Life
The Honor 9X Pro boasts an impressive endurance rating of 104 hours, indicating excellent battery life under typical usage. The Oppo F31’s battery capacity is unspecified, but its standout feature is its 80W wired charging, supported by 33W PPS and 13.5W PD. This charging speed dramatically reduces recharge times compared to the 9X Pro’s slow 10W charging. While the 9X Pro excels in longevity, the F31 prioritizes minimizing downtime. The F31 also offers reverse wired charging, a feature absent on the 9X Pro, adding to its versatility.
Buying Guide
Buy the Oppo F31 if you need incredibly fast charging, frequently use your phone throughout the day, and want a device with a more modern chipset for sustained performance. Buy the Honor 9X Pro if you prioritize maximizing battery life, are less concerned with the absolute fastest charging speeds, and appreciate a phone known for its endurance in everyday use.
Frequently Asked Questions
❓ How long does it take to fully charge the Oppo F31 with the 80W charger?
While a precise time isn't specified, Oppo's 80W SuperVOOC charging typically takes around 30-40 minutes to charge a comparable battery from 0% to 100%. The inclusion of 33W PPS and 13.5W PD adds charging flexibility with compatible chargers.
❓ Is the Kirin 810 in the Honor 9X Pro still capable of handling demanding games?
The Kirin 810 is a capable chipset, but it's now several generations old. It can handle most popular games at medium settings, but may struggle with the highest graphics settings in newer, more demanding titles. Expect some frame rate drops during extended gaming sessions.
❓ Does the Oppo F31's fast charging generate a lot of heat?
Oppo's SuperVOOC charging technology incorporates multiple safety features to mitigate heat generation. While some warmth is expected during fast charging, the system is designed to regulate temperature and prevent overheating. The Dimensity 6300's 6nm process also contributes to improved thermal efficiency.
❓ What type of display technology does the Honor 9X Pro use?
The Honor 9X Pro utilizes an IPS LCD display. While it offers a good contrast ratio (1319:1) and brightness (517 nits), it lacks the advanced features of OLED or AMOLED panels, such as true blacks and potentially higher color accuracy.
