Shut down uMPB, but the battery still loses charge?

I thought when you shut down a mbp, that means you power it off completely and no drainage should occur.

Every time I turn off my mbp late at night around 1am and turn it back on in the morning around 10, I seem to lose about 1% charge. I'll have 100% go down to 99% or I'll start off at 99% and in the morning, wake up to see its at 98%.



Also, I recently downloaded the Deep Sleep widget and tried it out. Going into Deep Sleep actually preserved my battery charge at where it was.

Someone shed some light?

Batteries lose about 1% per day when not being used.

Deep Sleep thing probably just does what a Mac does when the battery is totally exhausted - writes the RAM to the HDD and then shuts off all power. You may as well just shutdown.

The fact it didn't lose any charge is probably just coincidence. Maybe the normal discharge hadn't clicked over a full percent.
