Not exactly relevant as I've got a question about LP's battery life, but still. I've just moved to a G4 from Xperia Z2, which has a full HD screen rather than quad HD and 200 more mAh, but with the LG G4 I've got 40% of battery left after 12 hours of use with less than 2 hours of SoT, which seems pretty poor. Is this normal? Or does the software take some time to adjust itself?
