How much should battery go down overnight? 13Inch MBP 2012 i5

How much should the battery drain on sleep over say 7 hours?

I'm losing around 10% a night with no apps open in the dock and bluetooth off.

Does the 30 day standby only apply to the air?

I think it's supposed to be 1% per hour on standby. Mine is the same as yours.

That sounds about right. It uses roughly 1% of battery power for each hour of sleep.

Standby mode only applies to MBAs and MBP retina models.
