Embodiment one
The embodiments of the invention provide a kind of control method of intelligent power output amplification, Fig. 3 is one kind provided in an embodiment of the present invention
The schematic flow sheet of the control method of intelligent power output amplification.As shown in figure 3, this method can include：
S301, when receiving play instruction, detect the current electric quantity of battery.
In an embodiment of the present invention, terminal needs first to detect the current electric quantity of battery, is sentenced according to the current electric quantity of battery
Break if appropriate for opening intelligent power output amplification.
It should be noted that in an embodiment of the present invention, when terminal detection receives the play instruction for playing sound,
Terminal voluntarily detects the current electric quantity of battery.
Fig. 4 is the schematic diagram that a kind of exemplary terminal provided in an embodiment of the present invention receives play instruction.Such as Fig. 4 institutes
Showing, user sends play instruction by touch operation, to terminal, wherein, the sound that user needs to play is music 3, that is,
Say, terminal can know that user has carried out touch operation to the option of music 3, so as to receive the finger for playing music 3 by detection
Order, it is sound to be played to determine music 3, starts to detect current battery charge.
It is understood that in an embodiment of the present invention, reducing the power consumption of terminal, mainly pass through the battery according to terminal
Electricity point situation is realized.First, terminal judges whether to open intelligent power output amplification, because, in terminal plays sound, intelligent work(
Put and non-vital, and for a user, keep the electricity of terminal sufficient, meet use demand be it is most important, because
, when terminal is relatively low, power consumption of terminal can effectively be reduced by closing intelligent power output amplification, save the electricity of terminal for this.Secondly, terminal according to
The current electric quantity of battery controls the operating voltage of intelligent power output amplification, because, in the prior art intelligent power output amplification is with regular worker
Carry out work as voltage, the fixation operating voltage is generally large, then no matter the current electric quantity of battery is in which kind of state, terminal
Power consumption it is all larger, therefore, in embodiments of the invention, when terminal detects that the current electric quantity of battery can open intelligent power output amplification
When, terminal is that the operating voltage of corresponding intelligent power output amplification is determined according to the specific size of the current electric quantity of battery.
S302, when current electric quantity is more than default power threshold, open intelligent power output amplification.
In an embodiment of the present invention, terminal is after the current electric quantity of battery is detected, can according to default power threshold,
Judge whether to open intelligent power output amplification.
Specifically, in an embodiment of the present invention, when terminal detects that the current electric quantity of battery is more than default power threshold
When, intelligent power output amplification is opened, when terminal detects that the current electric quantity of battery is less than or equal to default power threshold, closes intelligent work(
Put.
It should be noted that preserve default power threshold in terminal, wherein, default power threshold can by user according to
Itself is daily to set to the service condition of terminal or actual demand, and the embodiment of the present invention does not limit specifically.
Exemplary, the default power threshold preserved in terminal is the 50% of battery total electricity.That is, when terminal is examined
Measure battery current electric quantity be more than battery total electricity 50% when, open intelligent power output amplification, when terminal detects the current of battery
When electricity is less than or equal to the 50% of battery total electricity, intelligent power output amplification is closed.
For example, the default power threshold preserved in terminal is the 50% of battery total electricity.When terminal detects battery
Current electric quantity be battery total electricity 35% when, terminal i.e. close intelligent power output amplification, when terminal detects the current electric quantity of battery
For battery total electricity 65% when, terminal i.e. open intelligent power output amplification.
Fig. 5 is that a kind of exemplary terminal provided in an embodiment of the present invention judges whether to open the schematic diagram of intelligent power output amplification.
Terminal is receiving play instruction, it is first determined whether opening intelligent power output amplification.If the default power threshold that terminal preserves is battery
The 60% of total electricity, as shown in Fig. 5 (a), when it is the 45% of battery total electricity that terminal, which detects the current electric quantity of battery, automatically
