So I recently got a new LG Vortex from Verizon. And I'm planning on taking it to school with me, but I have a quick question about volume. I set the vibrate thing to "never" so that doesn't bother me, but sometimes when the battery gets low, it will make a noise to warn you. If I hit the button that says silent mode which says it turns off every sound except media and alarms, does that mean it won't go off in class if the battery gets low? I want to make sure my phone won't go off at all during school. I don't want to turn it off so so please get back at me with a nice answer. Thanks!
