Method and system for controlling precharging currents of mobile terminal and mobile terminal

Abstract

The invention discloses a method and system for controlling precharging currents of a mobile terminal and the mobile terminal. The method includes the steps that when the mobile terminal detects that a charger is disconnected, instantaneous precharging current signals before the charger is disconnected are acquired; voltage stabilization processing and voltage reduction processing are conducted on voltage signals converted from the current signals; the voltage signals obtained after voltage stabilization processing and voltage reduction processing are converted into new current signals, and the converted new current signals are used for precharging the mobile terminal; when the new current signals are used for precharging the mobile terminal for preset time, the new current signals are amplified into the instantaneous precharging current signals before the charger is disconnected, and the instantaneous precharging current signals are restored again to charge the mobile terminal. By the adoption of the method and system, the problem that a mobile phone cannot be charged due to the fact that the precharging currents are too large in the prior art can be solved, and safety is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a mobile terminal precharging current control method, system and mobile terminal. Background technique [0002] With the development of mobile communications and the continuous improvement of people's living standards, the use of various mobile terminals such as mobile phones has become more and more popular, and mobile phones have become an indispensable communication tool in people's lives. [0003] Existing mobile terminals have more and more functions. Nowadays, in order to realize the function and characteristics of fast charging of smart phones, on the other hand, this is also a bright spot in the charging of smart communication devices. However, due to the large pre-charging current, the mobile phone cannot be charged during the pre-charging stage. That is, when the mobile phone is pre-charging, if the pre-charging current is unstable or the mobile phone ...
