How effective is Deep Sleep Mode? I got frustrated from turning on my Retina MBP and waiting a few seconds while the systems  loads from Deep Sleep Mode.

I disabled it using sudo pmset -a standby 0

However, I would like to know what I am missing now. Will I start losing a lot of battery power while the laptop is sleeping normally (basically not in Deep Sleep Mode) ?

For example, in 1 hour (or 2-5 hours), how much percentage will battery I lose on Sleep mode, and how much would I lose when its in Deep Sleep Mode ?
Your Mac might last a week in sleep where it might last a month in deep sleep.

If you travel with a power adapter or would rather end up with no battery than wait a few seconds longer each wake, then keep deep sleep turned off.
