    I recently had my MacBook Pro asleep for three days straight after fully charging, wifi off, and all applications closed. When I woke up my computer, my battery was down to 73%. Apple's official tech specs note that this machine should be capable of 30 days of standby time, not the 12 that I'm currently achieving at this rate. Are there any possible symptoms/solutions to this for anyone else that my have had this experience in the past? This is a consistent problem I seem to have. The only thing that I could think may be causing this is the fact that I have one of those Transcend JetDrive-like cards in my SD slot 24/7 in order to expand my storage. Could this be the problem?

    •Note my computer currently has 205 cycles and a full charge capacity of 91.4% according to coconutBattery, so it would appear my battery is in decent shape.
