Apparently its the setting time zone option in notifications thats causing the problem. Instead of just ticking periodically its constantly ticks which causes the battery to drain.
idownloadblog says "We have tested this method on 4 different iPhone 4s handsets, including an iPhone 4 and an iPhone 3GS. All have reported drastically improved battery life after switching ?Setting Time Zone? off."
turn your ?Setting Time Zone? switch to OFF in the Settings > Location Services > System Services (at the bottom of the page).
I just did this i don't know my results yet.. but i will update when i do have some .. hopefully this is it.
