They used the smartphone for a couple of months or years and suddenly found a problem with overheating - there are several explanations for this.

Why does the phone get warm when charging

  1. Damage to the switching power supply. In PSU, due to a power surge in the network, the microcircuit overheats, which either closes or changes the outgoing current. In such cases, both the smartphone and the power supply are heated. Since the PSU design is collapsible (unit and USB cable), the switching power supply simply changes. You can take it from a tablet or buy in a store. PSU repair is not practical.
  2. Bad contact of the charging cable with the phone. This happens if the smartphone lies on the edge of the table, the cord hangs constantly. In such cases, the PSU does not heat up, and the phone case is hot. You need to change the cable and check the quality of charging. In rare cases, you will have to replace the charge contact on your smartphone.
  3. Phone activity during charging. Many working online applications make the processor plow, which causes the smartphone to heat up. During charging, the corresponding services on the phone that control the power controller are launched. In aggregate, all applications load the processor even more. You just need to complete unused programs and put the phone on charge.
  4. Unsuccessful firmware. The problem affects cheap Chinese smartphones, which the manufacturer likes to release with a crude operating system. The Chinese themselves do not know why the phone heats up when charging. But they always recommend “rolling back” the firmware when problems arise. Apple products have no such problem.
