Display Comparison
The Oppo Ace2 features an AMOLED display, likely with a higher refresh rate (spec not explicitly stated, but common for the era) offering vibrant colors and smooth scrolling. The Galaxy S9+ also has a Super AMOLED display with excellent contrast and color accuracy. While both are great, the Ace2's potential higher refresh rate gives it a slight edge in perceived smoothness.
Camera Comparison
Both phones offer capable cameras. The Galaxy S9+ has a well-regarded dual-lens setup known for its image quality and versatility. The Oppo Ace2 likely has a more modern camera system with improved processing and potentially better low-light performance, though specific details are needed. Both offer good video recording capabilities.
Performance
Here, the Oppo Ace2 dominates. The Snapdragon 865 is significantly more powerful than the Exynos 9810 or Snapdragon 845 found in the S9+. Expect faster app loading, smoother multitasking, and better gaming performance on the Ace2. The S9+ is still capable, but it shows its age.
Battery Life
The Galaxy S9+ is the clear winner in battery life. Its endurance rating of 86 hours is exceptional. The Oppo Ace2's battery capacity is likely smaller, and while its 65W charging is incredibly fast, it won't compensate for significantly shorter battery life.
Buying Guide
Who should buy the Oppo Ace2? Gamers, power users, and those who value fast charging and the latest technology. Who should buy the Samsung Galaxy S9+? Users seeking long battery life, a reliable camera, and a familiar Samsung experience, especially at a budget-friendly price point.
