With respect... what is the point of a battery thread with a beta release. It is likely to change with each iteration
By the time it reaches public release nobody has bad battery these days any more from "normal" operation.
Very occasionally apple will release something that reduces battery.
Generally people get around 6 hours usage and a day of standby. You wake up, use your phone, get home, put it on charge.
If you are using your phone in bright sunlight with the GPS on and iTunes match and you happen to be in a low signal area or travelling and using your phone, your battery is going to blitz fast. if you install a dodgy app or something that uses background battery, same thing.
But in general i really don't see the point of these battery threads. In 99% of cases it is user error or due to using phone features. In the other 1% its a defect.
