Hello, OPPO's mobile phone supports the fast charge protocol. At present, the mobile phones that support the fast charge protocol, most of them have the phenomenon of charging heat. No matter which fast charging technology, chargers and mobile phones, there will be different degrees of heat, especially the use of mobile phones in the process of charging may reach the point of hot. Therefore, the owner of the mobile phone charging heat should be relatively normal, if the owner is not assured, it is recommended to go to the after-sales mobile phone detection, to see if there is really a hardware problem.
oppo mobile phone charger will heat up when charging because when the mobile phone is charging, part of the transformer in the charger is converted into heat energy, while the current through the conductor will also generate some heat, there will be a slight heating phenomenon, please rest assured to use. If the mobile phone charging hot situation is particularly obvious, you can bring the mobile phone and the original charger to oppo customer service center for testing and processing.
