Hello, this is my first post here and i'm really looking forward to help me. I have a Macbook Pro Retina 13" Early 2013 Running OS X 10.9.4 (13E28). The battery life was never an issue with me but i've been experiencing drastic battery drain on my laptop. It goes from 100% - 20% in 1.5 hours average. I downloaded all the battery apps on the Mac App Store to check my battery health and they all said it was normal and the number of cycles are 430, i know they're almost near half but does this affect the battery life in anyway? I really need help with this problem because it's driving me cray i can't do anything without making sure i'm next to a power outlet. The other thing is overheat, i sometimes find the laptop very very hot that i can't put it on my lap and the fans are always high until i stop doing heavy tasks on the computer. I really need your help guys, hoping that restoring isn't the solution. Thanks.
