Ok so I've heard different things when it comes to what to do with your phone right out of the box when it comes to the health of your battery. Usually when you first turn it on it has maybe 40-50% left on it. So what is the right thing to do? Charge to 100% right out of the box, drain to dead and recharge to 100% again. Or Don't charge out of the box and instead use it until dead and then charge to 100%, drain to dead again and recharge to 100%. I've also heard after this initial charge and drain you want to only do that again every month or so and try to keep your battery between 20-80% mostly to maintain a healthy battery. Is this correct?
