When a data cable fails to charge properly, you should first stay calm, then troubleshoot the problem step by step, identify the cause, and take corresponding solutions. 1. Check the power supply and equipment: Confirm whether the power supply is working normally. Check if the socket has electricity; you can try testing the socket with other electrical appliances. 2. Check the data cable: Inspect the appearance of the data cable - see if there is obvious damage to the data cable, such as breakage, distortion, loose interface, or oxidation of metal contacts. 3. Check the charging port: Clean the charging port - the charging port of the device is prone to accumulating dust, lint, and other debris, which may cause poor contact. 4. Check the charger: Confirm whether the charger is compatible - ensure that the output voltage and current of the charger meet the requirements of the device. 5. Troubleshoot software issues: Restart the device - sometimes the software of the device may have temporary faults, resulting in inability to charge. 6. Consider external factors: Ambient temperature - extreme high or low temperatures may affect charging efficiency. 7. Seek professional help: If the problem still cannot be solved after the above steps, there may be a hardware failure in the device or charging accessories.

The intermittent charging of a charger may be caused by various reasons. This situation will not only affect the charging efficiency of the device but also may damage the service life of the device's battery. To help users better understand and solve this problem, the possible causes will be analyzed from multiple aspects below, along with corresponding solutions. 1. Problems with the charger itself: The charger is one of the core components in the charging process. If the charger itself has quality issues or is aging, it may lead to intermittent charging. 2. Problems with the charging cable: The charging cable is the bridge connecting the charger and the device. If there is a problem with the charging cable, it may also cause intermittent charging. 3. Problems with the device itself: In addition to issues with the charger and charging cable, the device itself may also result in intermittent charging. 4. Impact of the external environment: The external environment may also have an impact on the charging process, causing intermittent charging. 5. Software problems: In some cases, software problems of the device may also lead to intermittent charging. 6. Other possible reasons: Besides the above reasons, there are some other factors that may cause intermittent charging.
