ive had this early 2011 MBP for a little over 2 years now, and beofre on its own power (battery not AC) it used to last about 7 hours of basic use meaning the sound off and brightness set at a little under halfway like 6 or 7 boxes. now it lasts about 3 on a good day. right now i just took the power out and as im writting this its dropped down to 96%.
This is my battery information, should i consider a new battery?
