Background cpu usage

[NoiseShaper]

Hi, I'm a BSPlayer Free user. I have had it installed in and old Lg Optimus One P500 with Android 2.3 and in a new Nexus 4 with Android 4.2.1. In both phones it works really well, except for one thing: after viewing a video and exiting the app, it remains running in background having some cpu activity and thus consuming some battery. You can check this using some process info app, such as SytemPanel Lite. It doesn't seem to prevent the phone from going into deep sleep, but consumes some battery when using the phone in other tasks. This is an issue for me, because after using the app I have to kill it so that the app doesn't drain the battery more than it should.

Thanks.
