I bought my 64gb 4s Friday night. I took it home and restored from a backup. I charged it to 100% and unplugged it before I went to bed that night at 2am. My results are below as soon as i reached 1% about 30 mins ago. I've browsed the web mostly on WiFi and have made a few calls along with testing out Siri several times (20 times?). I think these results are good even without having conditioned my battery, so I can only assume they will improve. I'm happy.
