Hi
This might be a very simple question but I'm going around in circle try to google an answer and not getting anywhere.
Basically I've turned an old iPhone sat in a drawer into a tracker for the car and this works perfectly fine. The problem is battery life as you would expect. I thought this would be easily fixed by putting in a battery pack that allowed pass through charging and job done. But it's not that simple, all power pack I can find that allow passthrough charging auto shut off once the phone is 100% charged. Therefore it charges once and thats it, the phone drains again but never starts the charging process again.
I've seen one suggestion of butchering the charge cable and putting a small resistor on the power lead, to trick it into always discharging but I'm not keen on this. I've also thought about installing a second aux lead acid battery and split charger and running it off that, which would be a easy option and did want to put an aux battery in the truck at some point. but its just annoying that it not a simply solution.
any suggestions? I'm I missing the obvious?
any help would be great.
