Is out there has tried the PersistentAssistant tweak from Cydia that enables Siri to keep on listening after she has last spoken (until she is dismissed using the home button). This should enable Siri to work like the commercials we see on TV where the celebrities are having conversations with their phones. I was wondering if users of this tweak have seen any drop in battery life? I ask because a few months back there was a tweak that allowed Siri to always remain in a listening state; that tweak killed my battery. I'm hoping this new tweak won't. It would be good to use while driving. I imagine you could even use it with "Dismiss Siri." Thanks.
