App battery drain?

[Major]

Recently my Nokia 920 has been exhibiting very poor battery life, probably on the order of less than 10 hours with very light use in a non-LTE area. The newest apps that I've installed are Voxer and WhatsApp. Are either of these known to cause battery issues? I only have 3 apps currently running background tasks (Dictionary.com, TVShow, and Weather Flow). Any feedback would be greatly appreciated. Thanks.
