I have been using my Bionic to stream Sirius radio for about 2 hours a day during my work commutes since release day. The Bionic has done a pretty good job of streaming, even though I drive through areas that force the Bionic to switch back/forth between 3G and 4G, and to deal with low signal areas. It would typically drop/recover once maybe twice an hour. Occasionally it would drop for a longer period, but it was hard to tell if it was due to the Sirius app, as the app would become unstable and eventually FC.
Yesterday I read a post about switching the battery mode to the Performance setting, which, according to available info on the Bionic shouldn't make a difference for streaming during daytime hours (I had kept is set to the default Nighttime Saver setting).
Well, for the past two commutes it's been 100% perfect, even with the frequently changing network conditions. Amazing!
Fortunately, streaming for 2 hours only reduces my battery by about 20%, and that seems constant with the new Performance setting.
