to drain or not to drain?

[Jongewehr]

hey guys had my MBP for about 3 months now.

i know your soposoed to cycle your battery once a month.

i have not fully drained my battery from start to finish..., i have put a number of cycles on it (maybe one a week) by using half an plugin it back in.

is this ok or do i still need to fully drain it. should i do it today or just once in a blue moon.

Apple recommends going it every two months or so. You should fully drain it. Run coconutbattery (free app) and post the results here.

ive had my MB for like 4 months now and have yet to do the full drain/charge thing. Will probably do it soon though.

Fully drain, going half wont do it.

what is the expected lifespan of an apple battery? is there a place where I can look at expected lifespan with good care and bad care for comparison?

I think the expected lifespan is about 1000 cycles.

[Jongewehr]

For the non-removable units, they claim >80% capacity through 1000 cycles, for removable batteries they say you should have >80% capacity though at least 300 cycles.

It's best to do a full calibration the first time you use it. Just let it go, I'd actually use it to play music or something that keeps it up and let it go until it goes into deep sleep. When you plug it in and push the power button it will start back with the same session. You can even take out the battery when it's in deep sleep and it will keep the session. I'd try to calibrate it every two months or so and you'll get good battery life. I've calibrated mine quite often and it just recently dropped from 100% to 98% health on 394 cycles and I've had it since October.
