No problem. I would like to rephrase it a little. I doesnt make sense.
Calibration does nothing but adds a cycle of usage to your battery and very slightly drain the health of your battery. Calibration is actually supposed to be used for syncing the battery chip that reads how much charge the battery could hold with the actually battery so it could be read with accuracy. Thats it. It does not improve battery health nor improve the longevity of the battery. Calibration should be at most done every 4 months or at least every 1 year.
How to keep your battery healthy.
When your are discharging...
1. Do not do any strenuous tasks. Play 1080p youtube videos. Play games or at least games like battlefield 4. If your palmrest is feeling a bit warm. Try to do less on your battery.
2.Try to use your battery at least once a week. Drain to around 15%. Let it rest for about an hour. Then charge. (No strenuous tasks while draining)
3.When recharging, do no do any strenuous tasks.
4. you could do strenuous tasks when its fully charged to 100% and plugged to the ac.
5. when you are not using you computer and you don't need your things saved and you are not planning to use it for a day or two and it is 100% charged. Fully Shutdown (not sleep) and unplug the ac. Sometimes your battery may drain to 99.5% or something... thats normal.
6. Apple tricks you. The instance the orange(red) light turns green its not at 100% yet. its at 95%. So let it stay green for another hour until doing any strenuous tasks.
7.Also, your battery acts as a buffer when you are on ac. So you shouldn't play heavy games like battlefield 4 or starcraft 2 or encode on imovie for no more than 2-3 hours a day
