If your data cable is not obviously damaged, but you can save it by not charging it

If your data cable is not obviously damaged, but you can save it by not charging it!

I don't know if you have encountered such a situation. The data cable still looks good and there is no damage. Why can't it be charged when charging?

If you encounter such a situation, you can try it like this, you can wipe the fourth contact point, because the contact point of the data line represents a different role. Some are used for data transmission, some may be accessory identification, and the fourth bit of the contact point is mainly used for charging, so the data line that has been used for a long time is generally the fourth bit becomes black, which makes it difficult to use. You can save the data cable by scratching it.
