Extending the life of your smartphone
It's just like any other slot or empty space, the USB port of our
smartphone also tends to store dust and debris inside it over time, but
this small seeming problem is sometimes the main reason for the death of
your phone. To avoid this, clean your smartphone regularly. Just take
a syringe full of air, insert its needle into the power jack, and inject
the air. This procedure will allow you to easily remove the dust from
the charging port and extend the life of your smartphone.
Hope you find these helpful.
