iPhone 4S 5.0.1

i have 32gb iphone 4s yesterday, updated ios 5.0.1. i'm noticing poor battery life (i charged 12% last night night 100%), , 3 hours later @ 77% after casual use. notice drains when use it, not when it's on standby. on ios 5.0, seemed last long time, 15 hours no charge if using casually, , 8-10 hours if using lot.

tips great battery life? use battery apps, battery doctor, don't see do. don't improve much. thought, should downgrade 5.0 , wait 5.1?

thoughts appreciated.

one method found helping little time zone setting. go settings > location services > , scroll way down , see system services. selcet , "setting time zone". turn off. affect time when travel different time zones, won't automatically change. small price pay extended battery life. i'm still researching other methods too. hope helps.
