I just got my first Android phone and its a Galaxy Nexus running Jelly Bean. The first two days I was getting around 4-5 hours of battery life and then started reading up on this forum and did a bunch of suggested changes like turning off NFC, location services etc. Also, downloaded Juice Defender and now the battery life is around 7 hours. My usage is very minimal and I was thinking the battery life should be much better than this. When I look into my usage, it seems Google Maps is eating out all my battery life. I have turned off all possible location services to stop this but nothing seems to work.
I have attached some of the relevant screenshots also from my device.
Any advice on how to get this sorted is much appreciated. Thank you.
