Can't tell man. Bluetooth on, ok. Using it how long? 1 minute? 3 hours?
Did you play games or did you just send a couple of mails and some whatsapps?
As for seen in the forums looks like average... I can tell you my battery life is way better than that but there are other users who have so poor battery lifes that would kill to have yours.
It all depends to how you feel about it. If it lasts the whole day and you can charge it every night then it's OK. If you need your phone to last at least 40 hours and you end up with a dead battery after 1 day then you'll need to do something about it.
