If your iQOO Neo 5s heats up while charging, this is probably normal. During the charging process, the battery will generate a certain amount of heat, especially when it is charged quickly. However, if the fever is too pronounced or lasts too long, there may be a problem. It is recommended that you check that the charger and charging cable are working properly and ensure that you are using the original accessories. At the same time, ensure that the charging environment is well ventilated and avoid using the phone for a long time or while charging. If the problem persists, it is recommended that you contact the after-sales service center for further inspection and repair.
