Jelly Bean in particular seems to have exceptional battery life. I can easily go 3 hours of continuous gaming before I start getting battery warnings. With Gingerbread I barely got an hour of continuous play on my older phone. With Jelly Bean, I get 3 hours comfortably (granted, my new phone has a larger battery, but it has a larger display as well).
You can go through the checklist of basics, such as turning down brightness, force closing open apps that you aren't using (Task Killer Pro is good for this), turn off Blue Tooth and/or WiFi if not in use, turn off background sync for email and other applications, etc. Individually, each of these items does not contribute much, but together, these changes do make a noticeable difference in extending game-play.
Assuming you have Android, you could also use an app called Titanium Backup (requires ROOT) to Freeze background apps, which further improves battery life.
