How to solve it without fast charging?

The mobile phone can't flash charge. Try the following methods:

First, the mobile phone does not display flash charging?

1. Enter Settings-Battery/More Settings to confirm whether to turn on the dual-engine flash charging (if there is no such switch, flash charging will be turned on by default).

2. Replace the phone's own lock screen style (use other or third-party lock screen styles, and the screen will not display flash charging related icons when charging).

3. Confirm whether the original charger and data cable are used.

4. The connectivity of the socket will also affect the charging. You can try charging with other outlets.

5. Disconnect the power supply, reset the phone for a period of time, and then try to charge it.

6, mobile phone settings-system management/more settings-backup and reset/restore factory settings-restore all settings.

Second, the mobile phone shows flash charging but no flash charging effect?

1. Try not to use your mobile phone when charging.

2. When charging, use one button to accelerate the cleaning of software running in the background.

3. Try not to recharge the phone after it is completely used up.

You can compare the same model in the physical store to see if there is any obvious difference in charging speed.

If the above methods still can't solve the problem that the mobile phone can't flash charge, you can take the purchase invoice, warranty card, mobile phone and charger to the customer service center for processing.
