Hibernate using lots of power

In my settings, I set my laptop to hibeate for everything rather than shutting down, sleeping, etc. I did a test last night, unplugging my laptop at 100%, then closed the lid (set to hibeate on lid close). I let it sit for about 90 to 120 minutes, opened it up, and it was at 95%. That's an awful lot of power drained for something that's supposed to be off. To be fair, I'm not sure if the laptop actually went into hibeate. I'm just assuming it did because that's how I set it. If there is a way to force hibeate, I'm certainly willing to test it again. As an FYI, I'm ruing Elementary OS (based off Ubuntu). Thanks in advance.
