Hello! I have an LG G4 from Verizon and after updating to Marshmallow (and even a little before then) my battery life has significantly declined. My phone used to get me through a full day and was fantastic but lately it has been terrible. I have no way of knowing for sure what is using my battery because the battery section of the settings isn't showing everything that is using my battery I think. I use the Google now launcher (and I would like to keep it that way ) and I just need some help please.
