My iPhone 4 doesn't use much battery at all on standby. I leave locations services, 3G and Wifi on all of the time but I don't fetch mail or have notifications on ever and if I'm not using bluetooth I turn it off. Notifications, bluetooth and fetching mail are some of the biggest battery drainers when not using your phone. Games will always burn a battery quickly.
