Display Comparison
Neither device boasts a standout display. While specific display specs (resolution, panel type) are not provided, both likely feature LCD panels common in this price bracket. The focus here is on internal performance, not visual fidelity. Bezels are expected to be moderate on both, and color accuracy will likely be standard for the segment. The absence of high refresh rates on either device suggests a focus on power efficiency rather than a premium visual experience.
Camera Comparison
Without detailed camera specifications, a direct comparison is difficult. However, it’s safe to assume both devices employ similar budget camera setups. The Realme 9i 5G likely benefits from the increased processing power of the Dimensity 810, potentially leading to better image processing and noise reduction. The Oppo A77 4G may rely more heavily on software optimization to compensate for its less powerful chipset. Expect both to struggle in low-light conditions, and avoid placing too much emphasis on any included 2MP macro or depth sensors.
Performance
The core difference lies in the chipsets. The Realme 9i 5G’s Mediatek Dimensity 810 (6nm) is a significant upgrade over the Oppo A77 4G’s Mediatek Helio G35 (12nm). The Dimensity 810 utilizes more efficient 6nm fabrication, resulting in better thermal management and power efficiency. Its CPU configuration – 2x2.4 GHz Cortex-A76 & 6x2.0 GHz Cortex-A55 – offers a substantial performance boost over the A77 4G’s 4x2.3 GHz Cortex-A53 & 4x1.8 GHz Cortex-A53. This translates to faster app loading times, smoother multitasking, and a more enjoyable gaming experience on the Realme 9i 5G. The 5G connectivity of the 9i further future-proofs the device.
Battery Life
The Oppo A77 4G’s 33W wired charging is a clear advantage, achieving a full charge in just 69 minutes. The Realme 9i 5G’s 18W charging is considerably slower. While battery capacity isn’t specified, the more efficient 6nm Dimensity 810 in the 9i 5G may partially offset the slower charging, offering comparable all-day battery life despite potentially having a smaller battery. However, users who frequently need to top up their phones quickly will strongly prefer the A77 4G.
Buying Guide
Buy the Oppo A77 4G if you prioritize fast charging and a consistently reliable, albeit less powerful, experience for everyday tasks like browsing and social media. Buy the Realme 9i 5G if you want 5G connectivity, smoother multitasking, and a more capable processor for gaming and demanding applications, and are willing to trade off some charging speed.
Frequently Asked Questions
❓ Will the Realme 9i 5G handle demanding games like PUBG Mobile smoothly?
The Mediatek Dimensity 810 in the Realme 9i 5G is significantly more capable than the Helio G35 in the Oppo A77 4G. While it won't deliver flagship-level performance, it should handle PUBG Mobile at medium settings with a reasonably stable frame rate. Expect some frame drops during intense action, but the experience will be noticeably smoother than on the A77 4G.
❓ How much slower is the 18W charging on the Realme 9i 5G compared to the Oppo A77 4G's 33W?
The 33W charging on the Oppo A77 4G can fully charge the device in approximately 69 minutes. The 18W charging on the Realme 9i 5G will likely take well over 2 hours to reach 100%, potentially closer to 2.5-3 hours depending on battery capacity. This is a substantial difference, making the A77 4G the preferred choice for users who prioritize quick charging.
❓ Does the Realme 9i 5G's 5G connectivity actually make a difference in everyday use?
Currently, the benefits of 5G are limited by network availability.
