Flash charge when hot
The so-called flash charge is to first charge with high voltage (12V\/9V), and then change back to 5V charging after reaching a certain value, when the high voltage is originally 5V needs 2000ma current is now not needed, which reduces the loss caused by large current in the transmission process, but does not mean that the speed of mobile phone charging is reduced into chemical energy. You don't deserve a flash charge if you do. So you can expect this flash charge process, the rate of conversion of electricity into chemical energy is faster, so it is hotter than normal charging.
The ideal operating temperature of the battery is between 15 ° C and 40 ° C. In order to protect the mobile phone battery, the system has set a low temperature protection, which automatically reduces the charging speed and the maximum charging power under low temperature conditions. In general, flash charge can be used normally
OPPO mobile phone hot can not flash charge, wait for cold and then charge it
