While not GREAT news, I don't see this as bad news. With a removable battery, it's a non-issue.
Plus, it seems only marginally worse than the G2, which everyone raves about battery life.
Phonearena battery test results
LG G2 6;48hours. 5.2 FHD 3000mAh .
LG G3 6:14hours. 5.5 QHD 3000mAh
It's not bad result for a phone with 5.5" QHD. But they haven't updated G2 battery test after KitKat update. GSMarena did it and G2 battery life got about 20% better than with JB.
