MacOS – Battery issue with MacBook Pro 13 inch (Early 2011)

I had the exact same problem (twice!) and had my battery replaced under warranty - I seem to recall there was a battery replacement program for this issue (don't quote me) but even if there was I suppose that would have finished now.

I'd say you might have a chance if you called and explained the issue or went into an Apple store depending on what kind of person you run in to.

There was also a firmware update that was meant to help solve this issue, but it didn't help me and I suppose you'd have gotten that through software update long ago.

Long story short: It's not that the battery isn't holding enough charge, and not that it's had too many cycles - evidently they just had an issue with their battery production, and your machine has taken this long to be affected by it. Hopefully you get someone nice from Apple, but otherwise a trip to eBay or somewhere else on the internet should be able to get you a new battery for relatively cheap.

Good luck, hope it works out for you.

It sounds like you've got a bad battery, no doubt, and should have it replaced, gratis. While this shouldn't be a problem, it won't hurt to have the most ammunition possible when you arrive at the store or have to place a call to Apple Care. Take a screenshot of the "Service Battery" menu icon (Shift + command + 3), and collect all the data you can (like the kind you've included in your question). I've had three defective batteries replaced by Apple, two of them close to the 300 cycle mark, which is what Apple guarantees 80% battery health to. The screenshots and data have been instrumental in getting a rapid, no questions asked replacement. Of course, if your battery is showing the health problems that it is after only six (!?!) cycles, then you've got a good shot at it anyway.
Good luck!
