LG3 vs LG4 battery life?

I'm sold on the LG4 phone, but my biggest question is the battery life.

phoneArena is pretty clear that battery life is no better than the G3.

Even on Marshmallow the G4 appears to lose to the G3 on Lollipop, which is disappointing.

But then AnandTech seems to indicate it's better.

If anyone is able to offer any of their own comparison to the G3, that would be very helpful.

Thanks
