I'm expecting my brand new GS3 to arrive tomorrow , and I'm wondering how I should charge it straight out of the box. Should I plug it in straight away, and leave it alone without touching it for hours and hours until fully charged? Should I just start using whatever residual charge is in the battery without plugging it in, until it switches off, then plug it in and fully charge for hours and hours without touching it? [does it in fact have a pre-charged battery?] Should I plug it in straight away to charge for hours and hours, but freely play with it while it is on charge? In short, I don't want to screw up my battery by doing the wrong thing to start with. I have heard that the battery system is different than that on HTC phones and requires a different process, but I don't have a clue who holds a definitive answer.
