My new base rMBP is draining battery with no usage. I first had (and still have) this problem with my 4s, and now it's happening to my new MBP as well. Great. Last night @ 10 pm - 83% This morning @ 6 am - Turned on and 77% Came home @ 5:30 pm - Turned on again and 69% That's an 8% decrease in battery life with no usage in between either times. I leave no programs running and nothing connected, I don't know what the problem is. Not impressed. I thought you could leave SSD's like the MBAir for up to 30 days with no usage, why am I having this problem?
