Hi guys, Received a new Macbook pro battery for my birthday present and replaced the aged battery that came with the MBP. Everything seems to be working normally. However, the battery somehow is acting like the old battery. It has dropped from 93% to 88% in the last 10 minutes with brightness raised to 13 bars and Chrome with a few tabs running in the background only. No other applications are running. My suspicions has led me to suspect that this could either be due to a faulty battery or the battery percentage is reporting off indications that don't represent the true percentage of the battery due to lack of battery calibration for first-time use. It's dropped to 86% now as I type this. Does anybody have a clue of which possibility might it be? MacBook Pro 15-inch, mid- 2010.
