    Hello, I'm a newbie here and I hope you guys can help me. This is my first mac, I bought a couple of months ago.

    Earlier on, when I was online my battery was 95% (around 8pm) I connected my ipad to my macbook pro (sync and charge at the same time) about an hour after that my MB battery run until 43%. Here's my questions. Does charging and syncing my ipad cause my MB battery run out quickly?

    Thank in advance :)

    Probably when it's getting close to 0%, if not a bit sooner.

    oh no, I normally charge my battery when its around 15-20%.. is that ok? and is it ok to plug in and use your macbook at the same time even though it's fully charge?

    It is okay to use the MB while fully charged and still connected to AC.

    Maybe take a look at the following, as it seems to answer most, if not all, of your battery questions

    I read some of it earlier, I don't understand this part 'Allow the battery to rest in the fully charged state for two hours or longer.'

    does it mean that after it fully charge for the first time let it connect for about two hours? I don't think I did that, I unplug right after it reach 100%.

    Yes, it means, you should have (but can do again, if you decide to do your next monthly calibration) left the charger plugged in for two more hours after the battery indicator showed "100%" or "Charged". AFter you waited two hours, you pull the plug. But no worries, you can repeat the process again, as calibration is only meant for proper display of the battery times and charges and health.
