Galaxy S4 Kit-Kat Update

Has anyone else noticed any dip in battery life with 4.4.2? I have had developer options enabled since I first got the S4 and always kept background processes at a maximum of two to help with battery life also in conjunction with power saving and Juicedefender Ultimate. Since the update the developer options do not work as I looked and saw that my app manager said 9 apps were running, then I release the RAM to only find it closed out 36 apps. I've never seen it close that many at one time. Anyone else? Any suggestions?

Updated to 4.4.2 yesterday. If you are using exchange push mail DO NOT update! Seems there is a big on 4.4.2 that makes the sync run continuously! Kills you battery, and jacks up your data usage. EAS was burning 4 mb an hour over wife (thank god) and was killing my battery in the space of 5 hours. I have factory reset my phone, at up and deleted the exchange account 3 or 4 times. Then I stayed looking online to find this is a problem in 4.4.2. Way to go at&t, this update had made my phone less useful...

Can anyone give a full review for this update....? some people said that it gives great battery life....

How can i set the setting to do that?

Its in Developers Options.
