Is anyone else experiencing a decrease in battery life after upgrading to IOS6? Just got my Ipad 4 and did the update right away and noticed it. I know there are a lot of discussions about it on the web (I wish I read it first before i did the update). I already have bluetooth and location services turned off and nothing is running in the background. This is for the Wi-Fi only model. I only have like 3 apps installed (Skype, Netflix and The Weather Channel). Thanks for the help.
