Bluetooth power consumption

Hi,
I am using an arduino pro 3.3v at 8Hz with the roving netwroks bluetooth module.Currently the battery power consumption with the bluetooth continuously streaming is about 45mA.I need to bring it down by atleast 10 to 15 mA so that the battery lasts around 8 to 10 hrs.

What are the possible solutions for bringing down power consumption?I am currently streaming data at 10HZ(115200 baud).Do you think streaming at a lower frequency may bring down power consumption?

Thanks
