Gaming with the Xiaomi Mi 11 Ultra
To truly witness the efficiency of the Snapdragon 888 chip, we invite you to immerse yourself in the experience of three graphics-intensive games: League of Legends: Speed Wars, Garena: Arena of Valor, and PUBG Mobile.
- League of Legends: Speed Wars
League of Legends: Speed Wars is no longer an unfamiliar game. It is renowned for its incredibly immersive gameplay, demanding high-performance devices for the best experience.
When testing League of Legends: Speed Wars on the Xiaomi Mi 11 Ultra, achieving the highest graphics level of 60fps is easily attainable. This foreshadows an extremely exciting and satisfying experience. Even during intense combat, with a stable network connection, frame rates remain at their maximum, ensuring players enjoy seamless battles.
The settings in this game can be set to the highest level with 'Graphics Quality - Ultra', 'Effects Quality - High', 'Resolution - High', and 'Post-Processing - On'.
After playing about half a match, the Xiaomi Mi 11 Ultra will start to heat up, with the highest recorded temperature reaching 42°C.
- Arena of Valor
Testing games on smartphones would be incomplete without Arena of Valor, which is currently captivating a large audience of young gamers.
For this game, the Xiaomi Mi 11 Ultra effortlessly pushes frame rates to 60fps, with moments even reaching 61-62fps.
Similar to League of Legends: Speed Wars, in Arena of Valor, the Xiaomi Mi 11 Ultra can achieve high criteria settings such as 'High FPS', 'HD Resolution - Ultra High', 'Image Quality - HD', and 'Detail Quality - High'.
Overall, the device heats up moderately without severe overheating, and instances of lag are almost non-existent, except when there are network disruptions.
- PUBG Mobile
Continuing the performance test of the Xiaomi Mi 11 Ultra with PUBG Mobile. This is perhaps the game that demands the highest configuration compared to the previous two tested games.
It's somewhat disappointing that despite the Xiaomi Mi 11 Ultra's 120Hz display, all settings can only max out at 60fps. However, the Snapdragon 888 chip still performs strongly, ensuring a stable gaming experience. Yet, it has not entirely met the expectations of many gamers.
Should you buy the Xiaomi Mi 11 Ultra for gaming?

Practically speaking, what users feel about the smoothness in games is reasonable given the Xiaomi Mi 11 Ultra's price of 19,990,000 VNĐ. However, despite its powerful chip, the Snapdragon 888 at the time of launch alongside the Xiaomi Mi 11 Ultra has not been fully optimized, so the gaming experience sometimes falls short of perfection. Of course, the high price of the Xiaomi Mi 11 Ultra is not solely because of the chip but also due to many other factors.
Should you buy the Xiaomi Mi 11 Ultra solely for gaming? It's quite expensive for that purpose. But if you're looking to explore many other features and especially if you have the budget, then this is still a reasonable choice.
