I know that it used to kill batteries when you would recharge it before it was low and needed to be charged. I also heard it was bad to take an item off of the recharger before it was at 100%. Does any of that hold true with today's batteries, meaning the one that is in the Sprint Hero? Can I recharge it at night if the battery is at 48% and have it not hurt the battery or it's life? Just wondering because I have a charge at work and home and wait till it is in need of charging. That is sort of a pain, I would rather turn the phone off at night and charge it and have a fresh and fast phone in the morning. Thanks!
