Moderate, like purposely controlled my excitement and made sure not to use it lol Send a few texts, made 3 or 4 calls went onto a few websites (maybe an hour of surfing), no wifi, no bluetooth, no fm transmitter, I even turn off the internet connection when not using the internet. So very moderate and it dies after 6 hours or less.

I told Nokia and they said to send it in, but Im trying to avoid waiting 10 days or longer to get it back...
