My SE w910i has no problem playing for my commute, which is about an hour total a day. Maybe takes about 20% of the battery for that plus an entire day of standby. Don't know about all day listening, but my headphones are too uncomfortable for that anyway.
I would think it is more the talking that runs the battery down and not just being connected to the BT set.
