Oppo Ace2
- Incredibly fast 65W wired charging
- 40W wireless charging support
- More compact form factor (implied)
- Faster wireless charging
- Slightly less powerful chipset than ROG Phone 3
- Camera details are unknown
Asus ROG Phone 3
- More powerful Snapdragon 865+ chipset
- Larger display for immersive gaming
- Gaming-focused features (implied)
- Long battery endurance
- Significantly slower charging speeds
- Larger and heavier design (implied)
Display Comparison
Both devices utilize a 7nm+ Snapdragon 865, but the ROG Phone 3’s display boasts a measured peak brightness of 719 nits, offering a potentially more visible experience in direct sunlight. While both have an infinite (nominal) contrast ratio, the ROG Phone 3’s larger screen size (unspecified in data, but known to be 6.59 inches) caters to a more immersive viewing experience. The Ace2’s display specs are not provided, making a direct comparison difficult, but its smaller overall footprint suggests a more compact screen.
Camera Comparison
Both phones feature capable photo and video capabilities, but detailed sensor information is lacking. Without specifics on sensor size, aperture, or OIS, a definitive camera comparison is impossible. However, the ROG Phone 3’s gaming-centric design suggests less emphasis on camera optimization compared to Oppo’s generally strong camera performance. The absence of details on both devices suggests neither is a primary camera-focused flagship.
Performance
The Asus ROG Phone 3 gains a slight edge in raw processing power thanks to the Snapdragon 865 5G+ chipset, featuring a higher peak CPU clock speed of 3.10 GHz compared to the Ace2’s 2.84 GHz. While both share the same CPU core configuration (1x Cortex-A77 at higher clock, 3x Cortex-A77, 4x Cortex-A55), the ROG Phone 3’s higher clock speed translates to marginally faster performance in CPU-intensive tasks. Both utilize the same LPDDR5 RAM, but the ROG Phone 3’s larger thermal capacity (implied by its gaming focus) likely allows for more sustained peak performance without throttling.
Battery Life
Both devices achieve an endurance rating of 120 hours, indicating similar overall battery life despite differing capacities (not specified). However, the Ace2’s charging capabilities are dramatically superior. Its 65W wired charging can fully charge the battery in just 30 minutes, while the ROG Phone 3’s 30W wired charging takes considerably longer. The Ace2 also offers 40W wireless charging (56 minutes to full) and 10W reverse wireless charging, features the ROG Phone 3 lacks beyond 10W reverse *wired* charging. This makes the Ace2 significantly more convenient for users who frequently need to top up their battery.
Buying Guide
Buy the Oppo Ace2 if you need the absolute fastest charging speeds available, a more manageable size for one-handed use, and a balanced flagship experience. Buy the Asus ROG Phone 3 if you prioritize sustained gaming performance, a larger display for immersive gameplay, and are willing to trade charging speed for specialized gaming features.
