So I was getting about 7 hours on my standard battery. I would put it on the charger after hitting 5 percent and let it charge overnight and take it off the charger at 9:15, I know this accuratley because this is when I leave for work. I would get to work where I dont use my phoneand when I leave my phone would be 70%. I used it for nothing. The biggest users were Idle and Standby. Then the smaller ones where Display, Android OS, and Android System. Where my bettery is going who knows; here are my statistics Wifi = off Locaton = off CMDA/LTE = ON Data Saver = Off -----Data Delivery Background data = ON Data Roaming = off Data Enabled = On -----Display Brightness at lowest Auto Rotate Screen = On Animation = On Screen Timeout = 30 Seconds Roaming Banner = On In Pocket Detection = On -----Location & Security Settings Google Location Services = On Standalone GPS = off VZW Location = ON Share Picture Location = Off -----Privacy Settings Back Up My Data = ON Automatic Restore = On My Battery Is on Maximum Battery Saver. So I got my extended battery yesterday and it was almost dead, stuck it on the battery charger that came extra with the costco deal and let it charge all the way up and then took it off. Then this morning I stuck the battery in turned it on and walked out my fron door. I used it for about 9 minutes for music and about 8 for internet. Its down to 40% from 100% this morning. Wtf.
