S3 not charging/home made charger.



Hi my s3 is no longer charging. The USB micro port is damaged.

I am not anywhere near my home at the moment and I really need the phone. So I made the most ghetto charger known to man. Which is basically just a stripped USB cable attached to some paperclips acting as springs to charge the battery when it is removed from the phone. This actually works surprisingly well and consistently charges to 88% in a bit over an hour.

However, what I'm really interested in (and I want to stress that this is only a temporary solution while I'm travelling) is what are the two gold pins in the middle, left on the back of the phone for?
I believe they are for attaching an extended battery to the back of the phone.

However I can't find any information on them, nor do I have a multimeter with me.

Can I just apply 4.5 volts to these two pins so I can charge my phone while using it?
Also which is positive and which is negative.

I just need a quick and dirty solution, thanks.
