Ask a question about emergency power [Copy link]

 

Hello everyone, I want to ask the next question about emergency power. Specifically, I bought a positioning watch for my child at home. When the child played with it until it ran out of power and turned off automatically, I lost it and couldn't find it. Shouldn't this kind of security product have a reserved power reserve? I want to ask everyone, if I want to modify it myself, I have to reserve some power for the battery as emergency power. How should I adjust the circuit or code? What is the general way to reserve emergency power?

This app is not easy to use, but the most important thing is the low battery reminder function.

I feel that it is not very useful for children who are too young to simply remind them. Those who know how to play will still play. It may be more suitable if there are reserved functions that only retain certain emergency functions and other operations cannot be used.

My daughter is like this. She doesn't care how much electricity she has. She will play with it when the adults are not paying attention.

If it is a product that is too difficult to modify, we can only provide a low battery reminder to parents, who can then notify their children to come back soon.

It seems that children's watches do not have emergency power function. I think it is better to directly choose a model with large battery capacity and long standby time.

In terms of hardware circuit, the power management circuit of the watch needs to be modified to stop supplying power when a certain power threshold is reached to reserve emergency power.

The software can also be modified, but it is also difficult for users. For example, it should remind users when the battery is low, and may provide an option for users to choose whether to enter emergency mode, etc.

Yes, the advanced version of Xiaotiancai has this function of emergency power. I don't think I have seen it in other brands. I just happened to do some research when I bought a watch for my daughter recently. No matter how big the battery capacity is, it can't stop children from playing non-stop. Of course, bigger is definitely better.

I agree. If we are talking purely from the software point of view, it would be better if the parent can set a certain battery level to force the system to switch to super power saving mode. I want a super power saving mode like the one on mobile phones. I think this is good.

This is a false proposition. If the phone can be played with, even if it has emergency power, it is likely to be placed in a fixed place by the child, making it difficult to

There is nothing we can do about it. Kids are very clever and always come up with new ideas.

I thought of one, when the battery is less than 10%, it switches to basic function mode. You can't open many apps
