Computer and phone batteries don't last long. Is it possible to have too much of something in my body that causes this to happen?

Well, what are you doing on the cell phones and computers? My cell and laptop battery last much longer when I'm not using them all day. My phone can go two days at least without charging if I don't get any calls or texts. But if I start texting or playing a game, basically anything, it can be dead within hours. Same with my laptop, if I keep the brightness down and I'm just doing homework, it tends to last longer than if I turn the brightness up and watch a movie on it.

And maybe it's the charging... I'm not sure, but I heard that if you put your batteries on charge for too long time, the batteries get a shorter life span over some time.
