I just picked up and activated my Nexus on Saturday and got all my apps on it and set everything up. But my problem is last night I went to bed, my phone was at least at 75%, I woke up and it was completely dead. So I threw it on the charger before I left for work, got to work, and the phone has been on the charger all morning and the battery level is dropping. I was at 51%, and then after like 20 minutes I was at 48%, now it's been on the charger for about 30-45 minutes and it's only at 55%. Something is killing my battery and I don't know what. I checked Battery under Settings and nothing absurd is using up all the power, I set my apps to not sync constantly. I have the power control widget and the only thing enabled atm is data sync and the display is on the lowest setting. What the heck is going on with my battery life?? I do not get 4G in my apartment, I found an article on how to shut it off in Settings because it supposedly is a huge battery waster. I might just cancel 4G all together, I don't get it at work, I don't get it in my apartment, the only time would be if I was out of my apartment. I have a great download speed and router at home anyway. The only thing I could think of was that I left WiFi on all night, but to drain 3/4th of my battery in about 8 hours?? When I didn't touch it at all during the time? Also I only have icons on the main home screen. And I have 2 widgets: the power control one and a Beautiful Widget's 4 day weather forecast. Facebook/G+ have been set to sync only once in a while, I think Facebook is every 4 hours. Also the phone has been on the charger since about 8:30AM this morning, and it's literally taken until 11 AM to charge from about 50% to 73% through the USB cable and my work computer. I understand USB charging takes longer but this is ridiculous, the phone is taking longer to charge than the use I get out of it!
