Is it better to let the battery run down to as close to zero as possible before charging? Should you charge your phone overnight while you sleep? Does that burn the battery out? If it only takes the phone an hour to charge, should you wait that hour then take it off the charger? Does it hurt the battery or burn the battery out by leaving it on the charger for hours after it is already fully charged?
So say my phone has 40% left at the end of the day...I put it on the charger and go to sleep...The phone is probably fully charged after an hour but sits on the charger for another 6 or 7 hours...Is that bad for my battery?
