I have an LG G4 and it bites me that the battery lasts a very short time. The battery purchased a new original 3000mAh Li-lon (with the old one the same) In the morning the phone charged to 100% and at 16:00 is 40% with rare use because I go to school and use it only practically at intervals. And in the description of the phone. He clearly writes that the battery lasts 1.5 days with heavy use so I don't know. The insight is not littered, it was recently zeroed by me and there is nothing that annoys me that I have to hook it up every now and then .
