To determine the authenticity of a Huawei mobile phone, you can take the following steps:

Query through official channels: You can verify it through the "Anti-Counterfeiting Query" function on Huawei's official website The authenticity of the phone. Enter the IMEI number of the mobile phone on the query page, and the system will return the authenticity information of the mobile phone.

Check the mobile phone packaging: Genuine Huawei mobile phone packaging usually has high printing quality and meticulous production, and the labels, text, patterns, trademarks, etc. on the packaging will also be very clear. If the packaging looks rough and has illegible writing, it's probably a counterfeit.

Check the appearance of the mobile phone: Real Huawei mobile phones also have certain process requirements in appearance, such as frame spraying, interface processing, etc. If the phone looks rough and has uneven corners, it may be a counterfeit.

Check the performance of the mobile phone: By using the official detection software of Huawei mobile phones or third-party hardware testing equipment, you can check whether the hardware performance of the mobile phone meets the official specifications. If the performance difference is obvious, it is likely to be a counterfeit.

It should be noted that if the Huawei mobile phone you purchased was purchased from informal channels or is a second-hand mobile phone, the above methods may not be able to fully determine its authenticity. Therefore, when purchasing a mobile phone, you should try to choose formal channels, and carefully check the appearance and performance of the mobile phone before purchasing to avoid buying counterfeit products.
