You all seem quite experienced in this, so I need everyone's guidance. I'm currently on JellyBam ROM and loving the new JellyBean features - but I'm disappointed in the battery life. Its not terrible, but its not the improvement I was expecting (and I manage whats running quite religiously).
Today, at the Google Developer day, I barely used it - except for some light browsing - but had WiFi on and connected the entire day. My friend had the same, except on his iPhone 3GS (iOS6). At the end of the day I was on 4% he was on 53%... To me thats shocking. So either my ROM/kernel isn't performing, my battery is stuffed or I'm not managing whats running as well as I thought (highly doubt it).
Anyway, for TL;DR: Need a ROM (or kernel?) with batter improvements, but that doesn't look terrible.
Thanks
