Xiaomi Black Shark 4S

  • Incredibly fast 120W charging
  • More affordable price point
  • Solid Snapdragon 870 performance

  • Snapdragon 870 is less powerful than the 888+
  • Potentially less refined software experience

Asus ROG Phone 5s

  • More powerful Snapdragon 888+ processor
  • Likely superior thermal management
  • Potentially better camera performance

  • Slower 65W charging
  • Higher price tag

Display Comparison

While both phones likely feature high-refresh-rate AMOLED displays (data not provided), the core difference lies in the processing power driving them. The Snapdragon 888+ in the ROG Phone 5s will deliver smoother performance in graphically intensive games, maximizing the benefit of a high refresh rate. The Black Shark 4S, while capable, will be more reliant on optimization to maintain consistent frame rates. The 5nm process of the 888+ also contributes to better thermal efficiency, potentially reducing screen dimming during extended gaming sessions.

Camera Comparison

Neither phone is primarily marketed for its camera capabilities, but the ROG Phone 5s likely benefits from a more advanced image signal processor (ISP) integrated within the Snapdragon 888+. While sensor sizes and lens apertures aren't specified, the ROG Phone 5s’s processor will likely deliver better image processing, particularly in low-light conditions. The Black Shark 4S will still be capable of taking acceptable photos, but the ROG Phone 5s offers a potential edge in image quality.

Performance

The Asus ROG Phone 5s boasts the Qualcomm SM8350 Snapdragon 888+ 5G (5 nm), a significant upgrade over the Black Shark 4S’s SM8250 Snapdragon 870 5G (7 nm). The 888+ features a Cortex-X1 prime core clocked at 2.99 GHz, offering a performance advantage over the Kryo 585 prime core in the 870. This translates to faster loading times, higher sustained frame rates, and improved multitasking. While both utilize octa-core configurations, the architectural improvements in the 888+ provide a tangible benefit for demanding applications. The 5nm process node of the 888+ also contributes to improved power efficiency, potentially leading to longer gaming sessions before thermal throttling.

Battery Life

The Black Shark 4S’s 120W wired charging is a standout feature, achieving a full charge in just 17 minutes. This is significantly faster than the ROG Phone 5s’s 65W charging, which takes 52 minutes for a full charge. However, the ROG Phone 5s supports PD3.0 and QC5 standards, offering broader compatibility. While battery capacity isn't specified, the faster charging of the Black Shark 4S mitigates any potential disadvantage from a smaller battery size, allowing for quicker top-ups during short breaks.

Buying Guide

Buy the Xiaomi Black Shark 4S if you need a high-refresh-rate gaming experience on a tighter budget and value incredibly fast 120W charging. It’s ideal for gamers who don’t necessarily demand the absolute highest frame rates in the most demanding titles. Buy the Asus ROG Phone 5s if you prefer a more powerful processor for consistently higher frame rates, a more polished software experience, and don't mind a slightly longer charging time. This is the phone for competitive gamers and those who want future-proofing.

Frequently Asked Questions

❓ Does the Snapdragon 888+ in the ROG Phone 5s overheat during prolonged gaming sessions?
While the Snapdragon 888+ is a powerful chip, Asus ROG Phone devices are known for their advanced cooling systems, including vapor chambers and heat spreaders. These systems effectively mitigate thermal throttling, allowing for sustained performance during extended gaming sessions. However, some throttling may still occur under extreme conditions.
❓ How does the 120W charging on the Black Shark 4S affect battery health over time?
Xiaomi employs charging algorithms designed to minimize battery degradation from fast charging. While fast charging generates more heat, the phone's software manages the charging process to protect the battery's long-term health. However, all batteries degrade over time, and frequent use of 120W charging *may* slightly accelerate this process compared to slower charging methods.
❓ Can either phone run Genshin Impact at 60fps with max settings?
The Asus ROG Phone 5s is more likely to consistently maintain 60fps with maximum settings in Genshin Impact due to its more powerful Snapdragon 888+ processor. The Black Shark 4S may require some settings adjustments to achieve a stable 60fps experience.
