Launched with a focus on gamers, the Xiaomi Black Shark 4 features cutting-edge performance capabilities, making it an ideal choice for mobile gaming enthusiasts. It includes features like fast refresh rate displays and advanced cooling technology to maintain performance during extended gaming sessions. Its aggressive styling and customizable controls provide an engaging user experience for those looking to game on the go.

This review is based on data sourced from benchmark results from UL Solutions and Geekbench, as well as user reviews from various forums including Xiaomi's official community. We analyzed the device's specifications, performance metrics, and user feedback to provide a balanced assessment.

Overall, the Xiaomi Black Shark 4 impresses with its powerful Snapdragon 888 processor and vibrant AMOLED display. While it excels in gaming performance and build quality, some users report concerns about camera capabilities and software updates, which could be limiting for those who prioritize photography.

How does the performance stack up for gaming?

The Xiaomi Black Shark 4 features Qualcomm's Snapdragon 888 processor, combined with up to 12 GB of RAM, which results in outstanding benchmark scores across the board. For instance, it achieved a Geekbench score of roughly 1,000 on single-core performance and over 3,300 in multi-core performance, positioning it among the fastest Android devices available.

Gaming on this device is augmented by its 144Hz refresh rate AMOLED display, which provides smooth visuals and responsiveness. Additionally, its Game Boost feature enhances performance further during high-demand gaming scenarios.

What are the physical attributes and durability of this phone?

The Black Shark 4 sports an aluminum frame and Gorilla Glass on both the front and back, contributing to a high-quality feel. It weighs in at 210 grams, which is heavier than some competitors, but this heft adds to its premium feel and durable build, important for gaming longevity.

However, users have noted that the aggressive design may not appeal to everyone, as it caters mainly to gamers with its RGB lighting and gaming triggers—features that some might find excessive in daily usage.

How does the battery performance compare to others?

Equipped with a 4,500 mAh battery, the Black Shark 4 offers decent longevity for gaming sessions, often lasting over 6 hours on heavy use. Notably, it supports 120W fast charging, allowing the battery to reach full charge in just about 15 minutes, which is a significant advantage for gamers who need to recharge quickly.

While the battery can sustain prolonged gaming, users report that gaming settings can drain the battery faster than regular use, which is something to consider for those who game extensively during the day.

How does the camera stack up against other features?

The camera setup includes a 48 MP main sensor, but real-world performance has drawn mixed reviews. Images in sufficient light tend to be vibrant, but low-light performance is often described as disappointing compared to non-gaming smartphones in the same price range.

Many users have expressed that while the gaming features of the Black Shark 4 excel, the camera quality may fall short for those looking for an all-in-one device.

Is the software experience user-friendly?

Running on MIUI for Games based on Android, the software offers tailored experiences for gaming, integrating various tools and optimizations for performance. However, some users report occasional issues with updates, which can affect overall usability.

The design is user-friendly for gamers, with easy access to gaming settings and a dedicated game mode, but the software might result in a less polished experience compared to other Android devices.
