Display Comparison

While specific display specs aren't provided, both devices likely feature high refresh rate AMOLED panels. However, the iQOO 11S, given its flagship positioning, is expected to have a higher peak brightness and potentially a more advanced LTPO implementation for variable refresh rate control, leading to improved power efficiency. The Ace 2, while still excellent, may exhibit slightly lower peak brightness and a less granular refresh rate adjustment range.

Camera Comparison

Without detailed camera specs, it's difficult to make definitive claims. However, iQOO phones often prioritize camera performance, suggesting the 11S likely features a larger main sensor and more advanced image processing algorithms. The Snapdragon 8 Gen 2’s ISP (Image Signal Processor) is also more capable than the 8+ Gen 1’s, resulting in better dynamic range, noise reduction, and overall image quality. The Ace 2 will still deliver respectable photos, but the iQOO 11S is expected to excel in challenging lighting conditions.

Performance

The core difference lies in the chipsets. The iQOO 11S’s Snapdragon 8 Gen 2 (4nm) represents a significant architectural leap over the Ace 2’s Snapdragon 8+ Gen 1 (4nm). The Gen 2 features the newer Cortex-X3 prime core clocked at 3.2 GHz versus the X2 in the 8+ Gen 1 at 3.19 GHz, alongside improved Cortex-A715 and A710 cores. This translates to approximately 10-15% better CPU performance and a more substantial 20-30% GPU performance gain for the iQOO 11S. Both utilize LPDDR5x RAM, but the Gen 2’s improved memory controller further enhances data throughput. The iQOO 11S will exhibit less thermal throttling under sustained loads.

Battery Life

The iQOO 11S’s 200W charging is a game-changer. While the Ace 2’s 100W charging is already fast (reaching 100% in 25 minutes), the iQOO 11S can likely achieve a full charge in under 20 minutes. This difference is substantial for users who frequently top up their phones throughout the day. While battery capacity isn't specified, the iQOO 11S’s more efficient Snapdragon 8 Gen 2 and optimized power management will likely offset any potential capacity disadvantage.

Buying Guide

Buy the OnePlus Ace 2 if you prioritize a slightly more established brand reputation and are comfortable with a 100W charging solution, potentially finding it at a lower price point. Buy the vivo iQOO 11S if you demand the latest processor technology, crave the fastest possible charging speeds, and are willing to embrace a brand known for aggressive performance optimization.

Frequently Asked Questions

❓ Will the iQOO 11S's 200W charging degrade the battery faster?
While 200W charging is incredibly fast, modern smartphones employ sophisticated charging algorithms and safety mechanisms to minimize battery degradation. The iQOO 11S utilizes PD3.0 and UFCS protocols, which dynamically adjust charging speed to protect battery health. Degradation will occur over time with any battery, but the advanced charging technology mitigates the impact.
❓ Does the Snapdragon 8 Gen 2 in the iQOO 11S handle graphically demanding games like Genshin Impact better than the Ace 2?
Yes, the Snapdragon 8 Gen 2 in the iQOO 11S offers a substantial GPU performance advantage (20-30%) over the 8+ Gen 1 in the Ace 2. This translates to higher and more stable frame rates in graphically intensive games like Genshin Impact, even at maximum settings. You can expect a smoother and more immersive gaming experience on the iQOO 11S.
❓ Is the difference in performance between the two chipsets noticeable in everyday tasks?
For basic tasks like browsing, social media, and video streaming, the difference will be minimal. However, when multitasking, editing photos/videos, or running demanding applications, the Snapdragon 8 Gen 2 in the iQOO 11S will feel noticeably snappier and more responsive.
