I have a Samsung Note and for some reason the S Note app is running and using 41% of my battery. I've tried stopping it in the Application Manager but the option is greyed out. I've turned the phone on and off twice. S Note isn't open on the phone itself but it drained my battery from 100% to 1% in 4 hours. It's still showing on battery manager as running and is the biggest use of the battery. Its driving me mad.
