    Hey everyone,

    Coming from a bionic, I would normally charge it whenever it got somewhat low and did not worry about destroying the battery(as it was replaceable). Now I have the maxx and want to know the proper way.

    Can I recharge the battery when it's 40% overnight and not worry about damaging or shortening the life of it?

    I understand that allowing the battery to fully drain and then charging calibrates the battery/meter.

    Thanks!

    Yep... 40% is fine. I charge whenever. It will not over charge. Occasionally drain down.

    I try not to drain too far. It takes forever to charge this bad boy back up. Lol

    Actually, you don't want to fully discharge the battery regularly. Once in a while to calibrate is fine, but lithium ion batteries really shouldn't be deep discharged every time. Lithium ion does not suffer from memory problems; regular deep discharges will actually shorten your battery's life.

    Just charge it at night and you should be fine.

    Charge it anytime and don't worry about it. Lithium based batteries like to be kept topped off and memory effect isn't an issue any longer.

    Nothing like a good battery that last through an entire day and than some! I went to bed last night with 50% battery left after pulling it off the charger at 6:30 am that morning. I watched news clips on CNN, MSNBC, Fox News, texting, Twitter, took a few pictures to test my camera and played Angry Bird...or tried to, Lol.... I still charged it when I went to bed though. Battery life is awesome. Enjoy!!!

    You are correct in noting that deep discharging a Li-Ion / Li-Po battery can and will damage it. However, under normal operating conditions, your phone is not capable of discharging your battery to a level below that which is safe for the battery. When your battery level meter says zero percent, that simply means that the battery has reached the pre-set low voltage cut-off that is programmed in the phone. At this point there is still plenty of charge left in the battery, however draining the battery further would damage it, thus the phone shuts off to prevent damage.

    There is absolutely NO HARM in letting your phone completely drain the battery on a regular basis. There is also NO harm in charging the battery from any level it happens to be at when you're near a charger.
