The National Intellectual Property Administration has granted OPPO a patent for "communication methods, power adapters and terminals". The technology, which covers the field of charging, can effectively avoid overheating when the phone is being charged.

According to the patent application file, before the power adapter charges the terminal, it receives the handshake information from the terminal. The power adapter determines the initial charging parameters according to the handshake information, which can effectively avoid the phenomenon of heating or even burning out the mobile phone caused by blindly increasing the voltage or current of the power adapter. According to OPPO, smartphones are increasingly popular with consumers, but they consume much power and usually need to be recharged frequently. As the battery capacity of smartphones increased, charging times get longer. However, in the existing technology, in order to achieve the purpose of fast charging, the output current or output voltage of the power adapter is usually increased without considering the bearing capacity of the smartphone, which will lead to the issue of overheating or even burning out of the smartphone, which reduces the life span of the smartphone.
