Display Comparison
Neither Oppo provides display specifications beyond resolution in their marketing materials. However, given the price points, both likely utilize LCD panels. The key difference lies under the hood. The A77s’ Snapdragon 680 ISP likely supports more advanced image processing for potentially better color accuracy. The A57e’s Helio G35, while capable, is less sophisticated in this regard. Bezels are expected to be similar on both, reflecting their budget positioning.
Camera Comparison
Without detailed camera specs, a direct comparison is difficult. However, the Snapdragon 680’s image signal processor (ISP) is generally more capable than the Helio G35’s. This suggests the A77s will likely produce images with better dynamic range and noise reduction, particularly in challenging lighting conditions. Both phones likely feature a primary camera and depth/macro sensors, but the A77s’ ISP will be better equipped to extract detail and clarity from the main sensor. We anticipate the A77s to have superior video recording capabilities as well.
Performance
The core distinction here is the chipset. The Oppo A77s’ Qualcomm Snapdragon 680 (6nm) boasts a more modern architecture and a smaller fabrication process than the A57e’s MediaTek Helio G35 (12nm). This translates to a significant advantage in power efficiency and sustained performance. While both are octa-core CPUs, the Snapdragon 680’s Kryo 265 Gold cores, clocked at 2.4 GHz, offer a performance edge over the A57e’s Cortex-A53 cores at 2.3 GHz. The 6nm process also means less heat generation, reducing the likelihood of throttling during extended use. The A77s will handle multitasking and moderately demanding apps with greater ease.
Battery Life
Both the Oppo A57e and A77s support 33W wired charging, but the time to full charge differs significantly. The A57e reaches 50% in 30 minutes, while the A77s takes 69 minutes to reach 100%. This suggests the A77s has a larger battery capacity, despite not being explicitly stated. The Snapdragon 680’s superior power efficiency further contributes to longer real-world battery life on the A77s, offsetting the longer charging time. Users prioritizing all-day battery life will benefit from the A77s.
Buying Guide
Buy the Oppo A57e if your primary need is basic smartphone functionality – calls, texts, and light social media – and you're prioritizing the absolute lowest price point. Buy the Oppo A77s if you value smoother multitasking, slightly better gaming performance, and longer battery life, even if it means spending a bit more upfront. The A77s is the better all-rounder for daily use.
Frequently Asked Questions
❓ Will the Snapdragon 680 in the A77s handle popular games like PUBG Mobile smoothly?
The Snapdragon 680 is capable of running PUBG Mobile at medium settings with stable frame rates. While it won't deliver a flagship gaming experience, it provides a noticeably smoother experience than the Helio G35, especially during prolonged gaming sessions due to better thermal management.
❓ Is the 33W charging on both phones equally fast in real-world use?
No, despite both supporting 33W charging, the A77s takes significantly longer to reach 100% (69 minutes) compared to the A57e (50% in 30 mins). This indicates the A77s likely has a larger battery capacity, and the Snapdragon 680's power management prioritizes battery health over ultra-fast charging.
❓ Does the Oppo A57e suffer from noticeable lag when switching between apps?
The Helio G35, combined with limited RAM (spec not provided, but likely 3-4GB), can exhibit noticeable lag when multitasking or switching between several apps simultaneously. The A57e is best suited for users who primarily use one app at a time.
❓ Which phone is better for taking photos in low-light conditions?
The Oppo A77s is expected to perform better in low-light scenarios. The Snapdragon 680’s ISP is more capable of reducing noise and preserving detail in challenging lighting conditions compared to the Helio G35’s ISP.
