Reason 1: If the mobile phone supports fast charging, but when charging the mobile phone, the standard fast charging electrical appliance or the standard fast charging data cable is not used, then the mobile phone can not be charged fast, only the use of the mobile phone's original fast charging electrical appliance and data cable can be fast charging, the use of other models of chargers or data cable is ordinary charging.
Solution: If you want your phone to charge quickly, be sure to charge it with the phone's original fast charge cable and charging head.
Reason 2: Contact is not real If the phone supports fast charging, and the original data cable and charging head are used when charging the phone, but the phone is still not fast charging, which can be caused by the false contact between the data cable and the charging head, or the false contact between the data cable and the phone jack.
Solution: At this time, re-plug the data cable, and the phone can be quickly charged after plugging. If the mobile phone supports fast charging, and the mobile phone is charged using the original data cable and charging head, and the interface has been inserted, but the mobile phone still can not be fast charging, which is likely to be caused by not opening the accelerated charging switch of the mobile phone.
Solution: On the desktop of the mobile phone, click the Settings option of the mobile phone, and then find the battery option in the Settings interface, find the advanced Settings option in the battery interface, and then find the switch for accelerating wired charging, and slide the function of the accelerated charging switch on, after the accelerated charging switch is successfully opened, the mobile phone can be quickly charged.
This could be because of several reasons:
1. The charger power is too high: the power of the fast charger is generally large, which may exceed the maximum power that the mobile phone can receive, resulting in the normal charging of the mobile phone. Ordinary charger power is small, suitable for the mobile phone needs charging power.
2. The charging line does not match: the fast charger and the charging line are used together, if the charging line is not the type required by the fast charger, it cannot be charged normally. The charging cable used by the ordinary charger may be matched with the phone and can be charged normally.
3. Incompatible charging protocol: The charging protocol used by the fast charger may not be compatible with the mobile phone, resulting in no fast charging. The charging protocol used by ordinary chargers may be compatible with the phone and can be charged normally.

If you encounter this situation, it is recommended to check the power of the charger, the type of charging cable, and whether the charging protocol matches the phone, or try to use another fast charger for charging. If the problem persists, contact the mobile phone manufacturer or after-sales personnel for further help.
There may be several reasons why you can't charge your phone with a fast charger:
< br >
1. Compatibility issues: Fast chargers usually support standard voltages and fast charging protocols (such as Qualcomm Quick Charge or USB Power Delivery). If your phone does not support these fast charge protocols, the charger may not be able to provide enough current to the phone. In this case, it may be more effective to use a regular charger.
< br >
2. Charger or charging cable problems: The quality of the charger or charging cable may have an impact on the charging effect. If there is a problem with your fast charger or charging cable, such as a damaged or incompatible connector, it may cause the charging process to be interrupted or an inability to perform fast charging, which a regular charger may not have.
< br >
3. Battery or phone problems: In some cases, it may be a problem with the phone itself or the battery that causes the fast charger to be unable to be used for fast charging. This can be due to an aging battery, software issues, or other hardware issues.
< br >
If you are having trouble charging your fast charger, you can try the following solutions:
< br >
- Check that the charging cables and chargers are working properly and make sure they don't have damaged or incompatible connectors.
- Try using different combinations of chargers and charging cables to ensure compatibility.
- Check that the charging port of the phone is clean and free of dust or dirt, so that it can be contacted normally.
- If the problem persists, you may need to contact the phone manufacturer or repair center for further diagnosis and resolution.
If your phone cannot be charged, please try:
1. Reinsert or replace the data cable or charging head. (Original packaging recommended)
2. For the mobile phone with removable battery, you can shut down and remove the battery, use a cotton swab to clean the battery contact and the mobile phone charging interface.
If the above method does not solve the problem, please bring the purchase invoice, repair card and the machine to the Samsung service center for inspection.
