Example, shall fall within the protection scope of the present invention.
In the specific implementation, mobile terminal includes but not limited to mentioned in the embodiment of the present invention：Smart mobile phone is (such as
Android phone, IOS mobile phones), tablet computer, laptop, palm PC, mobile internet device (MID, Mobile
Internet Device), the electronic equipments such as wearable intelligent equipment.The charging unit that the present invention implements mentioned by embodiment removes
Include above-mentioned mobile terminal, may also include mobile power (such as charger baby) or adapter etc. and can be used for filling to mobile terminal
The equipment of electricity.It should be noted that method described in the invention is performed by one group of code stored in memory, the generation
Code is implemented in the computer system based on von Neumann system.
A kind of charging method and device that the embodiment of the present invention is provided mainly need for a long time applied to mobile terminal
Booting is run and power consumption is huge, so as to need the scene frequently to charge.For example, the popularization experience in mobile terminal makes
With in the process, since experience user is numerous, for mobile terminal usually in the scene in high power consumption, power consumption is huge, and in order to move
It moves terminal energy normal use and mobile terminal is stolen in order to prevent, it will usually be connected with charging adapter with continual right
Mobile terminal charges.However, charging is larger to the loss of battery for a long time, when mobile terminal is in big power consumption scene
In, for example, running game and play video etc. scenes, the operating current of charging current superposition mobile terminal cause current total electricity
Flow larger, battery of mobile terminal and body temperature increase quickly, and some of which parts are also possible to breakdown short so as to cause
Road.The prior art is compared, the solution that the embodiment of the present invention is proposed can go control to fill according to the operating status of mobile terminal
The size of electric current, and the time of trickle charge is controlled, it is excessive that total current in mobile terminal can be prevented so that mobile terminal
With the temperature of battery it is excessively high the problem of, extend the service life of battery, and mobile terminal can be protected.
A kind of charging method provided in an embodiment of the present invention and device are specifically described below in conjunction with Fig. 1 to Fig. 5.
Referring to Fig. 1, it is a kind of charging method flow diagram provided in an embodiment of the present invention, goes to charging side as depicted
Method may include following steps：
When detecting that mobile terminal is charging, the operation of the mobile terminal is obtained with the preset time cycle by S101
Status information.
In the specific implementation, the executive agent of the embodiment of the present invention can be the charging unit in mobile terminal itself, also may be used
Be with mobile terminal carry out charging connection charging unit (such as charger baby or charging adapter).Week time can be pre-set
Phase, the time cycle are unsuitable too long or too short.In actual use, the temperature of mobile terminal and battery under normal circumstances
Tens seconds are usually required to a few minutes, therefore it is 1 minute that can set the time cycle.When charging unit detects mobile terminal just
In charging, the running state information of mobile terminal can be obtained preset time cycle, wherein, running state information include but
It is not limited to：CPU usage, number of processes, the amplitude of operating current and/or memory usage etc. can characterize to a certain extent works as
The information of the power consumption degree of preceding mobile terminal.
S102 according to the running state information, adjusts current charging current.
In the specific implementation, the running state information of mobile terminal represents the current power consumption journey of mobile terminal to a certain extent
Degree may determine that the size and mobile terminal of mobile terminal current operating current according to the size of function power consumption degree
Usage scenario.For example, when power consumption degree is big, usual mobile terminal is in and plays video, makes a phone call or running game etc.
Or in usage scenario, operating current at this time is also big；Power consumption degree hour, usual mobile terminal are in standby screen lock state,
Operating current is also small at this time.Therefore, it when the operating current that mobile terminal at this time is found by running state information is larger, can incite somebody to action
Charging current adjusts small；When the operating current for finding mobile terminal is smaller, charging current can be adjusted big；Cause charging current
Amplitude superposition with operating current is unlikely to also to be unlikely to too small greatly very much, prevents electric current excessive, leads to battery and mobile phone
Body temperature is excessively high, and the component in battery and mobile terminal is lost.
S103 with the charging current after adjusting, charges to the mobile terminal.
