She never kept it plugged in after the battery was fully charged, which means she was quickly using up her “400” cycles, or however many is the accurate number of cycles that a Macbook battery will last. What didn’t help was she was charging her Macbook fully, unplugging the charger from it, and using it until the battery died, charging it back up again, using it until it died, etc.

On top of that, her previous battery had completed 530 cycles before it went bad, so it seems as though both of our batteries have plenty of life left, although I do plan on buying a new Macbook Pro soon. Just in case you’re wondering, Apple says that you can get 400 cycles out of a battery, but that seems to be conservative, as her battery has completed 379 cycles and iStat Pro says its health is 97%, and iStat Pro says my battery has completed 430 cycles with a health percentage of 88% (see image below).Ī screenshot of iStat Pro on my black Macbook You actually should do that EVERY TIME you drain the battery fully, which you should do ONCE A MONTH to keep your battery healthy. So after trying different things, she decided to turn it ALL THE WAY OFF, and THEN charge it fully.
This didn’t really make much sense, because she had just gotten a new battery a little over a year ago, and the program iStat Pro ( great FREE widget for your Mac’s Dashboard) said that the battery’s health was 98%. When this happened, she tried unplugging the charger from her Macbook to see what happened, and it would just turn off right way (the screen would go black, all the lights would go out), as if the battery were dead. Soon after it said to replace it now, it said that it was going to take 20 hours to recharge and was STUCK on 20 hours (the battery was no longer charging). My sister just had an issue with her white Macbook (2008) where first it was saying “Replace Battery Soon,” and then it was saying “Replace Battery Now.”
