If your Huawei mobile phone is slow to charge, you can try the following methods:
1. Check whether the charging cable is damaged or stained. If yes, replace or clean the charging cable.
2. Check whether the charging port of the mobile phone has dust or stains. If yes, clean the charging port with a cotton swab.
3. Check whether the phone is in the fast charge mode. If not, switch to the fast charge mode.
4. If you are using a third-party charger, please try to replace the original charger.
5. If the fault persists, contact Huawei customer service for help.
If the fault persists, contact Huawei after-sales service center or online customer service.
Maybe there's something wrong with the battery, or maybe the charger is broken.
