Hi,
Did anyone ask this before?
I was thinking about maybe creating a cell phone charging 'regulator' to regulate the amount of charge that gets to the cell phone arther than just let it charge and charge or charge up to 100 percent and then disconnect manually.
Here is the thought that goes behind this.
First, i find that even if i dont use my phone i have to charge it every day or two. It does not need a full charge at those times so it is not too bad, but still day after day repeatedly charging and discharging it's going to kill the battery sooner than later.
So the idea is to regulate the charge (Ampere Hours) that gets to the phone so it mainly only powers the background tasks while the phone is mostly inactive but not powered off completely. This would be similar to maintaining a battery when it has some self discharge where you dont want to charge it just keep it topped off.
The ideal charge state is probably around 85 percent, so the regulator would have to supply just enough current to maintain the background tasks while not actually charging the battery anymore and NOT forcing it up to 100 percent charge which is not a good idea for long term.
I am thinking maybe even a series resistor might do the trick, although it would not be at the perfect level it might get close enough. So the cord would have to be broken and a series resistor of some value inserted in series with the power input to the phone. I guess a more advanced method might be to regulate the input to some voltage level like 4.5v instead of 5.0v or maybe regulate to 20ma (with included top voltage regulation) or something rather than 450ma which would be a normal charge current.
