Yesterday a single iPhone 5 running iOS 6.1.2 (Apple-iPhone5C2/1002.146) contacted our Microsoft Exchange 2003 server in the neighborhood of 50,000 times. Apparently iOS 6.1.2 hasn't resolved the Exchange client problems, at least in our case.

Used 6.1.2 for more than a week now....it did improved my battery in my IPhone5, however, it goes from 100% to 99% in just 27mins of standby and 5mins of used.
I shut down the Iphone and restart...it seems to be better.
Slight improvement only...not huge improvement...I bet Iphone 6 will be better
