Wife's Bionic Vs My first full day on s3.
Hers was used mainly for calls and texts, brightness is set to 1/3.
S3 was heavy internet, games and app usage, from setting up and deleting unwanted apps. Brightness was full, with no battery saving options. live wallpaper, photo widget rotating 2 photos.
I don't know why some people are down on the Bionic. My wife's has been a workhorse. we had about the same screen time (2h 15m) but she was 30% after 12 total hours. I was down to 6% after 10h (full screen brightness). I was trying to test the battery by running and testing applications and games that I had from my Droid 1 for deletion. I will try to search out more battery saving options an hope to stretch out my time.
