    I have a Late 2012 MacBook pro thats on Sierra. I bought a brand new battery for it, and recently have been noticing a huge drain on its battery. I have battery logger and its telling me my battery is in perfect condition and has its max capacity. Whenever I put it to sleep at night it'll be near or at 100% and for today as an example I turned it on 20 hours later and it had 65%. And after 11 minutes of use its at 55%. Is this a Sierra issue, or something wrong with my computer, and ideas would be helpful.

    I could be wrong, but I thought new batteries need to be conditioned or optimized when they're brand new? Beyond that, I agree with the above poster - was it an official Apple Battery? That could contribute to the issues.

    Use activity monitor to see what is using the most power, something must be running to drain the batter that fast.

    It was a new battery from I think Macsales. I bought it back in July or August and it worked perfectly until recently, so I'm not sure it's a calibration issue or something like that. I checked the battery status and on Batterylogger it says it has a 102% capacity out of a possible 100% and under About this mac the battery condition is normal.

    I noticed battery drain also in Sierra in my Macbook air mid-2013. Fix is easy, going back to El Capitan or Mavericks ;)

    Has the battery improved in latest Sierra update?
