Google Nexus 7 first gen. When playing Magic 2014 the battery drains even while charging... I'm trying to find ways to keep the battery from running out so quickly. I already disabled bluetooth and auto brightness, and lowered screen brightness. Here are my other ideas: - disable wifi - download a battery-lengthening app (I think I will go with "GO Battery Saver &Power Widget") Though I am wondering if multiple users causes the system to drain battery more quickly. I sure hope not. By the way I am new to android.. is Force Stop the only way to manually close apps or is there another way?
