bluetooth with 2.2?

[klister]

So prior to the froyo update i used my SE mw600 wich is a bluetooth headset and listened to spotify offline monday - friday 6:30 - 16:30 and i never got home with less then 50% battery. Now after the update the last few weeks havet been awful, i come home with about 30% and sometimes egen as low as 20% battery left. Where did my 20% go? No its not facebook in the background still have the old one. Any One got any ideas?

check the partial use history

in dialer type *#*#3646#*#*
select battery history
choose partial wake usage

any app using much more than others?
