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.
