Electronics/Alarms for Battery Power consumed in Electronic Gadgets.
Is it possible to build electrical circuit with alarms for indicating Battery Power consumed in electronic gadgets viz cameras, toys, watches, calculators etc ?.
For example :
Similar to alarm which we manually set in clocks, the electrical circuit designed will calculate the battery power consumed and when it is say 10% battery power remaining (low on battery, drained), alarms will buzz to the consumer as warning signals before 2-3 days in advance for the respective electronic gadgets. This process will be automated.
Awaiting your reply,
Thanks & Regards,

So many battery operated products already have various kinds of warning features built in. In the case of cpu driven products such as PC or tablet the use of battery power is not constant but fluctuates up and down depending on the computing functions going on. Therefore, predicting the power usage 2 or 3 days in advance may not be a very reliable computation.
Good idea but already in the features of many products that - at least those that can cost justify the cost of adding such features.
