After detecting system current battery charge, in the step s 120, battery electric quantity is resolved further
Up time, typically state can be set according to the total electricity of battery, current electric quantity and current switch and draw
Weight estimate user's pot life.In the battery electric quantity up time specifically can include both sides
Hold: one, be to calculate the battery electric quantity up time under minimum electric quantity consumption use state, if
The battery electric quantity up time under low electric quantity consumption use state uses duration less than expectation battery, then should
This transmission charge prompting signal；Its two, be to estimate the battery electric quantity up time under currently used state,
If the battery electric quantity under currently used state can use duration to be less than this expectation battery and use duration, then may be used
To send low electricity power saving cue, in order to according to this low electricity power saving cue, system is switched to
Corresponding low electricity power saving uses state, judges the battery electricity under minimum electric quantity consumption use state the most again
Whether the amount up time uses duration less than expectation battery, the most then should send charge prompting signal.
So, when electricity is relatively low, uses state by entering into low electricity power saving in advance, can avoid filling
The problem that before electricity, battery electric quantity the most all consumes.
After obtaining the battery electric quantity up time, it is possible to judge that battery electric quantity can according to step S130
Whether the use time uses duration less than expectation battery.This battery uses duration to be generally the upper of user preset
The duration value of quitting time section, the most workaday commuter time, the time of going on business and travel time etc.,
By arranging the beginning and end of these time periods, obtain expectation battery the most simply and use duration.Work as electricity
When the pond electricity up time uses duration less than this expectation battery, show charge in time, economize on electricity,
Even should shut down under extreme case, change battery, otherwise in this time period, battery will exhaust, and thus can
Make troubles to user.
After above-mentioned judged result characterizes the battery electric quantity up time less than expecting battery use duration, step
Rapid S140 can send an electricity accordingly and safeguard information.In the present embodiment, electricity safeguards information
Can be charge prompting signal, thus remind user to charge in time, so can avoid in the default time period
Interior running down of battery and cannot normally use the situation of the equipment such as mobile phone.Here charge prompting signal can be sound,
The various ways such as light or vibration signal, by this easily perceivable signal, can point out user easily
Take the measures such as charging in time.In the present embodiment, electricity safeguards that information can also be low electricity power saving
Cue, it can make user system be switched to the lowest according to this low electricity power saving cue
Electricity power saving uses state, is achieved in the economize on electricity of portable type electronic product.
Embodiment illustrated in fig. 1 have be charged within the important period, the function of the active warning that economizes on electricity, its
By judging whether the battery electric quantity up time uses duration to trigger charging or joint less than the battery preset
Electricity cue, thus solves user of interest, on and off duty or be not limited only to the commuter time
Enough electricity whether can be kept in material time section with the normal problem using equipment, thus improve product
Moral character energy, preferably meets user's request.
Such as foregoing teachings, step S110 can be passed through monitor application programming interfaces to the battery electric quantity of system
Register one and monitor module, detect this system current battery charge.In this case, system can open
Move the electric quantity change message of a background service monitoring system and message is filtered, it is determined that for low electricity
Time, can thus trigger charge prompting signal or low electricity power saving cue, remind the user that and fill in time
Electricity or economize on electricity.Combine Fig. 2 further below to be described.
See Fig. 2, it illustrates according to an embodiment of the invention, in FIG detecting system the most electric
The procedure chart of amount.In Fig. 2, monitor module monitoring application programming interfaces registration to the battery electric quantity of system
Afterwards, detecting system current battery charge detailed process is: first, and receiving the monitoring of system battery electricity should
The electric quantity change message (such as step S210) provided with routine interface；Afterwards, electric quantity change message is filtered
(such as step S220)；Finally, collect the electric quantity change message through filtering and calculate system present battery
Electricity (such as step S230), obtained system current battery charge specifically with percentage ratio, spacer-frame and/
Or the form such as anticipated pot life represents, intuitive is preferable.
From foregoing description, the premise of the embodiment of the present invention is to need detecting system present battery electricity
Amount；It is to be understood that the frequency of detecting is the highest, result is the most accurate；But detecting frequency is the highest, system
Burden the heaviest, too increase system power consumption simultaneously.To this end, the embodiment of the present invention have employed Frequency
The technical scheme of detecting, is further described below.
Refer to Fig. 3, it illustrates according to an embodiment of the invention, for adjusting detecting system in Fig. 1
The procedure chart of the detecting frequency of system current electric quantity.Its basic ideas are, reach at system current battery charge
During one low electric-quantity monitoring value, improve the detecting frequency to system current battery charge, specifically: start
Time, the detecting frequency of initialization system current battery charge is relatively low frequency (such as step S310)；Then
By the frequency surveillance system current battery charge (such as step S320) that this is relatively low；Judge that system is the most electric again
Whether pond electricity reaches default low electric-quantity monitoring value (such as step S330), and this low electric-quantity monitoring value ratio is low
Power threshold exceeds certain proportion, for example, the 30% ~ 40% of battery Full Charge Capacity；At system present battery electricity
When amount is less than this low electric-quantity monitoring value, the detecting frequency of initialization system current battery charge is higher frequency
(for example, 2 ~ 3 times of initial value), then system continues detecting system battery according to this higher frequency
Electricity.
In figure 3, owing to being concerned only with the electricity near battery " low battery state " (low state of charge)
Amount situation of change, thus reduce the burden of systems stay detecting battery electric quantity, lower the most further
System power consumption, this is conducive to further power saving undoubtedly.
In above example, after system enters into the desired battery saving mode of user, typically should reduce all
It is activated the renewal frequency of application, is so conducive to reducing further the power consumption of system, the most preferably
Realize power saving purpose.
As it has been described above, the battery electric quantity up time includes the battery electricity under minimum electric quantity consumption use state
The battery electric quantity up time under amount up time and currently used state.In the current use state
Battery electric quantity can use duration be less than expectation battery use duration but under minimum electric quantity consumption use state
The battery electric quantity up time more than expectation battery use duration time, can send charge prompting letter
Number, now can first make system enter into low electricity power saving and use state；Until minimum electric quantity consumption uses
When the battery electric quantity up time under state uses duration again smaller than expectation battery, just send charge prompting
Signal, thus reminds user's charging.It is described in detail further below.
Refer to Fig. 4, it illustrates the stream of battery electric quantity support method in accordance with another embodiment of the present invention
Cheng Tu.This embodiment includes power saving prompting function and charge reminder function: the former can be according to currently used
Under state, battery electric quantity can use duration to carry out prompt system and enter low electricity use state, thus can be preferable
Realize the purpose of power saving, this use time being conducive to extending battery, use such that it is able to preferably meet
The major demands at family；The latter's battery electric quantity under minimum electric quantity consumption use state can use duration to be less than the phase
Hope that, when battery uses, prompting user charges in time, so that battery keeps enough electricity.It is specifically real
Existing process comprises the following steps:
Step S410, detecting system current battery charge, concrete method for detecting can refer to embodiment illustrated in fig. 1
Description content.
Step S420, resolves the battery electric quantity up time, specifically includes the minimum electric quantity consumption of calculating and uses
Battery electric quantity up time under state, the battery electric quantity up time estimated under currently used state,
Wherein: the battery electric quantity under minimum electric quantity consumption use state is mainly in order to be charged prompting；Currently make
It is mainly used in power saving prompting, in order to battery can make before charging with the battery electric quantity up time under state
With the longer time.
Step S430, it is judged that under currently used state, whether battery electric quantity can use duration less than expectation battery
Use duration, if so, enter step S440；If it is not, return step S410, i.e. continue detecting system and work as
Front battery electric quantity.Rule of judgment in step S430 is equivalent to set a low power threshold, and it is the most electric
The 15% ~ 25% of pond Full Charge Capacity, can trigger system according to this Rule of judgment and enter into low electricity use state.
Step S440, sending low electricity power saving cue, thus prompt system enters low electricity and uses shape
State, thus extend service time of battery.
Step S450, judge that under minimum electric quantity consumption use state, battery electric quantity can use whether duration is less than
Expect that battery uses duration, if so, enter step S460；If it is not, return step S410, i.e. continue to detect
Examining system current battery charge.
Step S460, sends charge prompting signal, thus reminds user to charge in time, so can avoid
Preset time period in running down of battery and cannot normally use the situation of the equipment such as mobile phone.
In embodiment illustrated in fig. 4, before sending charge prompting signal, first send low electricity power saving prompting
Signal, is thus switched to system corresponding low electricity power saving in advance and uses state, so can extend electricity
The use time in pond, it is to avoid the problem that battery electric quantity the most all consumes before charging.
In the present embodiment, system can be switched to this low electricity power saving make by closing some power consumption switch
Use state.Make in addition it is also possible to system is switched to this low electricity power saving by unlatching a certain battery saving mode
With state, this battery saving mode some operational factors relevant to system power consumption of association and/or on off state
Set.Accordingly, this battery saving mode includes optimal battery saving mode, super long standby time pattern and limit power saving mould
