i am sorry to revive this thread, but as of friday my phone started this also. i turned off gps notification because i noticed it was on all the time. my phone has been fine since. today i turned it back on and it came right back to what it did friday. i checked the battery meter and b-w is using 50% now. i shut down b-w and it shuts off the gps notification and it is fine. i just uninstalled b-w.
