Battery life is a hotly debated issue. Generally I would follow the idea of Waiting for my cell phone battery to Reach 10-20 percent and then charge it. According to an article on gizmodo, apparently if you are using lithium ion batteries, it's best to charge them once the charge reaches 50 percent for best battery life! Which basically would entail plugging in nearly every chance I get. Kind of confused. I would always discharge battery fully and then only charge it. What's your take on it? What do you follow? Discharge to decently low levels and then charge or charge once it drops below 50? Or charge every chance you get?
