Batteries and cold weather just don't do good.

As far as the XD80s and I have several the battery life has out done all my other cams. Now battery life is less with the Plot option as one would expect. Plots take lots of pictures over a 2 to 4 hr period so one needs to understand battery life will be poor. I have not tried the video yet but have used the 'Hybrid' (Plot camera morning and evening and a trail cam at night) with good success.
And I have used the trail cam only and my battery life has been fantastic. But then the norhther woods of WI have not been all that bad. But now it is in the teens so I expect my battery life to go down hill compared to warmer weather.

Now I have not used the Lithium batteris only Alkaline. Tho Lithium will last longer I buy my AA batteries in bulk and do watch for sales. I have 8 Xd80s!

And you might consider re-chargeables. I ahve used a few of them and they work well too.

Good post would like to know what others do as I may learn something here!
