    Precisely, as I stated in my post. Thought that’s what the OP was trying to do.

    But the OP had already run the battery to 0 and charged it, so it is calibrated. No reason to repeat the process.

    Ok, I took your previous post to the OP as saying he shouldn't have done it at ALL (based on your reply here, I now see you meant to refer to his repeat drain, not the initial one), that's why I posted the clarification.

    Yep, it was targeted at the repeat he said he planned to do.

    That said, personally I see zero need for any calibration run at all. Just use the battery and in the course of use you will eventually end up with the battery going very low, which will then calibrate the software. I rarely use the battery, so I don't need to know if I'm at 48%, or 24%, or whatever. When I do use the battery because I have to, I just use it until it warns me it's about to die or until I can get it back on mains, whichever comes first.

    But I guess if you really want a well-calibrated battery meter, and if you don't care about abusing the battery a bit, you can do a calibration run.

    Different folks, different strokes...
