Full Battery is 2 Hours MacBook Air 2014
Bough my Macbook air in August of 2014; battery life has been running fine and haven't had overheating problems. Recently (March 2015), after updating my MacBook air to OS X Yosemite 10.10.2 operating system, it has been overheating constantly on the left side of the notebook and at a full charge, the battery only lasts 2.5 hours max. Is this a seriously problem that I should contact someone at Apple, make an appointment with a genius about, or just drain the battery and recharge it the full battery and hope for the best? Thank you.
MacBook Air, OS X Yosemite (10.10.2)
