After waiting for nearly six months before Nokia 920 launch I finally bought it two days after launch on 12th January, 2013. Overall I am very happy with it especially, after changing from iPhone 4. A lot of friends are asking about performance of Nokia 920, about camera, apps and especially battery life. So I decided to do a detailed analysis of battery life for it. Thanks for the great app Battery that helped me do this. I kept my phone on charging in the night and make sure it is fully charged...
