The models and chips of the two are different.
1. Different modes. Xiaomi's 5G mobile phones use an external baseband mode, while Huawei's 5G mobile phones use an integrated mode.
2. The chips are different. Xiaomi's baseband uses Qualcomm's 5G chip X55, which takes up the internal space of the phone, increases design difficulty, and consumes a lot of power. Huawei's baseband uses an integrated Balong 5000 chip, which saves the internal space of the phone and saves more power than an external baseband.
