Is the Black Shark phone easy to use? Can anyone tell me what I've used?

Xiaomi Black Shark mobile phone,

Personally, apart from not being suitable for playing games, there is nothing wrong with it.

Once you play games, the battery will run out in 3 hours. The fever is severe.

There is another question. All Black Shark phones cannot be charged in winter, and they use up power very quickly in winter. Even when not playing games. The battery will run out after a period of use.
