I have the Samsung Galaxy s6 and I've recently noticed that my battery has been draining faster than usual. i looked at the battery usage and noticed that the Visual voicemail is the major battery consumer. I don't know why. I've tried uninstalling updates, force stopping, clearing caches and data; for some reason I can't disable it, it's grayed out. All is fine and dandy, but when I get a text message, it's like it wakes up my visual voicemail and it starts up again. Anybody know what's going on?? How can I fix this or turn it off for good? Please help!
