Huawei's mobile phone battery life is 80%. Should I change it?

Don't change the battery for 80% of this brand of mobile phone.

When the health of Huawei's mobile phone battery reaches 80%, the battery still maintains good performance, which can meet the needs of most daily use. If the standby time of the mobile phone is not significantly shortened and there is no sudden drop in power, then 80% battery health is completely acceptable.

However, if the mobile phone is used for a long time, the standby time is obviously shortened or the power is abnormally reduced, even if the battery health is still 80%, you can consider replacing the battery.
