A short circuit is a fault that occurs when two points in a circuit come into direct contact, causing the current to bypass the normal path. When a short circuit occurs in the charger, the current may flow to other places through an abnormal path, which may cause the charger to burn or produce burn marks.
However, just because the phone wasn't significantly damaged doesn't mean it wasn't affected in any way. Mobile phones usually have built-in circuit protection mechanisms that can prevent problems such as excessive current or overheating. When an abnormal circuit is detected, the phone may automatically disconnect the charging connection to protect itself.
Even if there are no obvious problems with the phone, it is still recommended to check the status of the charger and charging cable to make sure they are not damaged.
The charger shorted and there were burn marks, but the phone was fine.
Because the charger is an internal short circuit, it will not affect the data line, and the large current will not pass through the data line to the mobile phone charging port.
You now find a charging bank or find another power source to plug in the phone and charge the charging cable.

If the phone is working normally now. It can be charged normally. So it's pretty much a chargers burn.

This situation will occur when the general charger is of poor workmanship or damaged. This guy is a short circuit and this is a short circuit.

If you're sure the phone works. There's basically nothing wrong with cell phones. It is recommended that you change a new charger, be sure to change the original official charger.
That's because there's overload protection in hand
