When charging your phone, you may find the charger or charging cable warming up, even so hot that it is difficult to touch. Although this is a fairly common phenomenon, if it persists, it can reduce the life of the device, damage the battery and pose a serious risk of fire and explosion.
Using poor quality or un genuine chargers
Floating chargers, unknown origins or not in accordance with the phone's standards are the leading causes of overheating. These chargers do not have a suitable self-adjusting power line mechanism, which can easily lead to overload and unusual heating.
Charging in high- Temperature environments
Charging a phone in hot environmental temperatures or placing it on a non-heating surface (such as a blanket, mattress) also makes the charger heat up faster. This affects the cooling efficiency and causes the charger to operate at excess capacity.
Using a phone while charging
Charging and using the phone, especially when playing games, watching videos or surfing the web, requires the device to charge and consume electricity at the same time. This causes both the charger and the phone to work continuously, leading to rapid heating and easily overheating.
Charging cables or charging ports are broken and loose
An underground, old, or unstable charging cable can cause unstable power lines, causing congestion and heating up the charger. If left for a long time, this can damage both the charger and the phone battery.
Charging the battery for a long time or overnight
Plugging the charger in for too long, especially overnight, causes the charger to continue working even when the battery is full, causing heat and affecting the durability of the component.
errors in battery management software or system
Sometimes, the phone software or battery management system itself has problems, causing the charging process to occur abnormally, leading to the charger being hotter than normal. Too many update errors and background applications are also related factors.
Advice for safe use
Always use a genuine or compatible charger recommended by the manufacturer.
Do not use the phone while charging, especially for a long time.
Avoid charging in high temperatures, humid areas or on non-heating surfaces.
Regularly check the condition of cables and chargers, and replace them if there are signs of damage.
Update the software to make the battery management system work stably.
