Abstract

The invention provides a terminal which comprises a state acquisition unit and a current regulating unit, wherein the state acquisition unit is used for acquiring a real-time state of the terminal; and the current regulating unit is used for regulating the size of a charging current of the terminal according to the real-time state. The invention also provides a charging current regulating method. By the technical scheme adopted by the invention, the size of the charging current can be automatically regulated according to the state of the terminal, so that the influence of the heating of the terminal on user experience is reduced.

Description

Technical field [0001] The present invention relates to the technical field of terminal power management, in particular to a terminal and a charging current adjustment method. Background technique [0002] The charging of mobile phones and other terminals is divided into three stages: trickle, constant current, and constant voltage, and the constant current stage occupies a long time in the entire charging process. In existing solutions, the maximum current drawn by the terminal from the charger in the constant current phase is often set to a fixed value. As the battery capacity of smart terminals increases, the problem with too small charging current is that the charging time is too long. Therefore, for terminals with large-capacity batteries, the prior art usually uses large currents to charge the terminals. The disadvantage of the high-current charging scheme is that it will cause the terminal to heat up seriously. If the user is holding the terminal for operation at this tim...
