I've personally noticed it to be "back to normal" and able to last 2-3 days on a full charge for my usage.

As for my personal usage habits, I usually leave wifi off during the day since I don't have access to the company's wifi. I just usually use it the whole day (roughly 5 hours or so) as an mp3 player while doing work. When I get home, it goes through about 1 hour tops with the wifi on.

Usually lasts me two to three days like this before the battery flats. Back when I had chinook it would only last me a day tops. I even had to keep a charger on my desk at work just in case.
