How to Charge Batteries .....Tips

    I know there is already information on this topic ..... I have read conflicting advice on how to charge cell phone batteries, but I want to make sure and get the maximum use and life from the ZeroLemon 10000 Extended Battery for my Note 3 .....

    The directions from the company simply state to give six full charges, but there is no explanation exactly what that means. I have sent the company a question regarding this issue, but still have not yet received an answer .....

    I just finished the third full charge. When I received the battery, I charged it for 12 hours before unplugging from the charger. Then allowed my Note 3 to go completely dead (to Zero %). Then charged again for 12 hours. Did this three times so far.

    I'm only getting around 37 hours of medium to heavy use, or about 1 1/2 days, and around 18-20 hours of Screen On Time, which seems somewhat impressive!

    After I go through six charging cycles, should I always charge for 12 hours, or is this no longer necessary?

    You should charge until the charger shuts off (or indicates a full charge, whichever the charger does). Or, if it's a battery that goes into the phone, until the phone tells you that the battery is fully charged. (I don't think that one goes into the phone, though.)

    The idea is that if the battery has been sitting on a shelf for months (and even Zerolemon wouldn't know that - they buy the batteries and put them together, they don't manufacture them), 3 (you don't really need 6) full charge/discharge cycles will recondition the battery. If the battery is fresh (and even near full charge), it won't hurt anything.

    In addition, to get the longest life from Lithium Ion batteries, they should be charged when they drop down to 40%-60%. You don't have to be a fnatic about it - if you're going to be out all day and probably drop the battery to 35%, that's fine, but if you usually charge at the midpoint, you'll get the maximum number of charge cycles.

    When charging overnight should the phone be turned off?

    I don't think you need to go 6 full cycles like that.
    3 should be more than enough.

    also letting a battery drop to 0.. does a little damage too.
    do not let it go to 0.. unless it is an emergency

    you don't need to turn it off when charging.

    best to charge it around 30-50%

    just charge till it is full.. no need for 12 hour charges.

    20 hrs of onscreen is good. wish my laptop can get past 3hrs.
