How to calibrate a Mugen Power 4600mAh extended battery on S3?

[Guest grizzlydroid]

So, I got myself an S3 and a 4600mAh battery for it.

The question is now, how to calibrate the battery so the phone will actually use the extra capacity?

I've been looking into this everywhere and there is no info about it, however I've heard a lot about this process.

It's even described in the manual that comes together with the battery, but there they just say to charge it 4-5 times a for 8-12 hours and claim that it's gonna be enough...

Does anyone have any suggestions or ideas about this?
