Display Comparison
Neither device boasts a standout display. Both likely utilize LCD panels, a common cost-saving measure in this price bracket. However, details like peak brightness and color gamut coverage are missing. The focus here is on the internal hardware, as display quality is likely similar. Bezels are expected to be moderate on both, prioritizing affordability over an immersive edge-to-edge experience.
Camera Comparison
Without detailed camera specifications, a direct comparison is difficult. However, it’s reasonable to assume both phones feature a primary camera and supporting lenses. The Infinix Note 12 Pro, given its focus on overall performance, may incorporate a slightly larger sensor or more advanced image processing algorithms. The Oppo A77 4G likely prioritizes software-based enhancements to compensate for potentially less capable hardware. The presence of a 2MP macro lens on either device is largely a marketing tactic, offering limited practical benefit.
Performance
The core difference lies in the chipsets. The Infinix Note 12 Pro’s Mediatek Helio G99 (6nm) is a significant upgrade over the Oppo A77 4G’s Helio G35 (12nm). The G99 features two Cortex-A76 cores clocked at 2.2 GHz, paired with six Cortex-A55 cores at 2.0 GHz, offering a substantial performance boost over the A77’s four Cortex-A53 cores at 2.3 GHz and another four at 1.8 GHz. The 6nm process of the G99 also provides superior power efficiency, reducing heat and improving sustained performance. This means the Infinix Note 12 Pro will handle demanding games and multitasking with greater ease and less throttling.
Battery Life
Both devices support 33W wired charging, achieving a full charge in approximately 69 minutes for the Oppo A77 4G. However, the Helio G99’s 6nm efficiency in the Infinix Note 12 Pro translates to lower power consumption during typical usage. This means the Infinix Note 12 Pro will likely offer longer battery life, even with a similar battery capacity (which is not specified in the provided data). The G99’s efficiency allows for more sustained performance without rapidly depleting the battery.
Buying Guide
Buy the Oppo A77 4G if you prioritize a familiar brand and require a basic smartphone for light tasks like calls, messaging, and occasional social media browsing. Buy the Infinix Note 12 Pro if you value performance for gaming, multitasking, or running demanding applications, and want a more future-proof device within the same budget.
Frequently Asked Questions
❓ Will the Infinix Note 12 Pro struggle with demanding games like PUBG Mobile?
The Helio G99 chipset in the Infinix Note 12 Pro is specifically designed for gaming. While it won't deliver flagship-level performance, it should comfortably run PUBG Mobile at medium to high settings with stable frame rates. The 6nm process also helps mitigate thermal throttling during extended gaming sessions.
❓ Is the 33W charging on the Oppo A77 4G significantly slower than on other phones with higher wattage?
33W charging is a respectable speed for this price range. While some phones offer 65W or 120W charging, the difference in real-world charging time isn't always dramatic. Both the Oppo A77 4G and Infinix Note 12 Pro achieve a full charge in around 69 minutes, meaning the wattage isn't the sole determining factor.
❓ Does the Infinix Note 12 Pro’s software have a lot of bloatware?
Infinix phones have historically included some pre-installed apps. However, recent iterations of their XOS software have improved in this regard, allowing users to uninstall many of these apps. It's still advisable to check for and remove unnecessary software after initial setup.
