Bad battery life when using custom watch face. topic

To start, I'll say I was moderately impressed with the moto 360 battery life when I got it a couple weeks ago based on all the poor things I had heard about it. My issue however is that it seems like if I use any watch face other than the stock ones that come installed already, the battery struggles to last more than 3 hours. When using something like minimal or classic (pre installed faces) I have no trouble getting 18 hours and having a bit to spare.

Could an element like having a weather display be whats hurting it so bad? I think most of the faces I tried show weather, but only update every hour or two hours. I can not imagine one or two updates eating up 80% of the battery.
