I hope you come back and fill in some details.
- what software did you use on the phone?
- plans for the box?
- a bit of an explanation about the circuit?
Looks like you put a lot of effort into it and it's a shame it doesn't show here.
The phone/laptop/etc charging circuit will stop battery from being "over charged" as in "Over voltage" but that isn't (as I understand it) what this "device" is for.
This is to stop the battery from being continually going through the charged-discharge cycle multiple times and dying from over use(charging).
The batteries of Phones/laptops/etc discharge even if the device is off.
This means that the charger will start charging them again to fully charged.
If you leave them plugged in this cycle will happen many times and the battery will wear out.
It happens a LOT with laptops that are used on a desk and alway plugged in.
I like the idea and I've been thinking about the same "type" of idea for Ni-Cad batteries for the same reason. Over charging.
If you move the Arduino after the relay so it's power is removed when the relay if off.
The entire device will become inert and use no power.
To activate you could add a simple push button in parallel with the relay to power up the circuit and start the cycle.
I'll keep an eye on this one for the actual circuits when you create them.
