Expected battery drain on sleep for rMBP

[appleminion]

I'm noticing battery drain on sleep for my early 2015 13" rMBP - I've unplugged all USB devices from the laptop before putting it to sleep and also unchecked the box for Power Nap in Energy Saver. Here are some of my measurements:

100 --> 96 in ~6 hours (0.67% decrease per hour)
54 --> 49 in ~7 hours (0.71% decrease per hour)

Is this normal compared to what you've experienced (please post your average decrease per hr)? Also, I did not quit out of Safari before putting it to sleep - could Safari be draining the battery even when it's sleeping? How do I further decrease the power used when sleeping without shutting down- do I need to put it in deep sleep?

I recently purchased the new '15 rMBP and have been noticing a similar phenomenon. I havne't had time to investigate yet or even pay closer attention to the rate of discharge during sleep.

I know I have the settings configured so that it doesn't do the iCloud updates during sleep-forget what that feature is called. All peripherals are disconnected while it's sleeping as well.

Would be ineterested to know if others are having this same issue.

100 --> 96 in ~6 hours (1.5% decrease per hour)
54 --> 49 in ~7 hours (1.4 % decrease per hour)

Yep 4-5% overnight is about what I get. Turn it off and it'll be better not perfect but much better about 3% every 24 hours

Your numbers are perfectly normal, even a bit on the low side of things. One should expect about 1% per hour. Less than that with a MBA.
