Is your smartphone not charging properly? Do you think the USB could be the issue? Don’t panic ! Before you take your precious mobile to a repair shop, or get out the soldering iron yourself, or think about changing models, you can try cleaning the USB slot.
It may be that like most people, you keep your smartphone in your pocket and that the problem stems from the dust, or, more accurately, the lint buildup in your pockets. This micro-fluff can prevent your USB charger cable from making good electrical contact. You can quickly check this out by looking to see whether there is tissue residue on your male charger, or the female slot.
The solution to this very common problem is extremely simple. It requires neither technical knowledge nor any special equipment. All you need is a wooden or plastic toothpick (don’t use any needle-like metal objects as this can damage the slot).
It is recommended, although not necessary to turn off your phone. Insert the toothpick into the slot and gently scrape. In a few seconds you will have removed the
hidden lint. Repeat the process until you have completely cleared the slot.
An alternative solution would be to use a compressed air kit to blow the lint out. Either way that you chose, check that the contact patches are clean before connecting your USB charger to your phone.
This is a good habit to get into as ultimately it can avoid bigger problems down the line if you leave this issue unresolved. Another good thing is that these steps can be used on all types of smartphone charger (micro-USB, USB-C, etc.), whatever the brand. And also tablets: although they rarely fit in a pocket, they can gather dust and lint in other ways.
