    Hi everyone,

    If I were to begin charging my phone mid-day when my battery's at about 40%, would it hurt the battery? With my older phones (and current laptop), and I had always heard that it was bad to charge a battery before its near-dead and even worse to unplug it before it was at 100%.


    Thanks!
    Ty

    Go ahead and charge it whenever you like. The new lithium-ion / polymer batteries have no memory.

    Am I right in thinking though its a good thing now and then to totally drain the battery then fully charge without unplugging or is that just a myth?

    It's not a myth. While it will in fact cause the life of the battery to shorten very, very slightly, it is required to do it once in every 30 charges in order to recalibrate the gauge which measures how much charge is left

    As he said , full discharge/recharge to calibrate the meter but otherwise is just wearing out the battery. A consumer grade lithium ion battery is good for 300 or so cycles, so if you discharged it fully every day you would wear it out in a year.
