Normal.
Because the iwatch needs to convert electrical energy when charging, some heat will be generated, so there will be a certain amount of heat during charging, but this will not affect the normal use of the iwatch.
If the iwatch overheats during charging, it may be the quality of the charger is not good or there is a problem with the charging port of the iwatch. It is necessary to replace the charger or repair the iwatch in time. It should be noted that the original charger should be selected when charging, and ensure that the charging port is clean and not wet, so as not to affect the charging effect and the life of the iwatch.
Normal because the iwatch is charged through the magnetic connection, it needs to use electromagnetic induction to generate current to charge, and the process of generating current will cause certain heat, so it will feel hot when charging.
This is a normal phenomenon of iwatch charging. It should be noted that if the iwatch is excessively hot when charging, it may be caused by battery damage or charger damage, and it needs to be checked and repaired in time to prevent safety accidents.
General heat is normal, but the temperature is too high is not normal, when charging the charger in a ventilated place, not on the bed or in the middle of the clothes, easy to heat.

It is normal for mobile phones to heat up when charging, especially for mobile phones that support fast charging and super fast charging. When charging, the current and voltage are larger, so the temperature will be higher than that of ordinary charging.
