I read a comparison of the Verizon GNex and the Nexus 5 and it said the Nexus 5 battery life was better BUT he also said his Verizon GNex battery was dead after 6 hours, even if not used. It said the Nexus 5 has about twice the battery life. So for that person that would put the Nexus 5 at 12 hours with no use? My GSM Gnex lasts about 24 hours with medium use. Am I going to lose battery life by upgrading? Or were the Verizon models worse as far as battery life?
