When the OS is updated, we often experience somewhat faster battery drain for a while. Depending on how many apps you installed, or degree of changes you made since the last update, your phone might be busy working in background to conform to the new OS. I believe the biggest background activity is the reindexing of Spotlight or accumulated messages, or cleaning up some garbages left from previous OS version etc. These should subside in 24 to 36 hours. I usually experience this but learned a long time ago to leave it and not worried about it. It will "return to a regular programming before" you notice.
