    Hello Guys,

    I have a question. Are there any special requirements to format Apple Watch 4 battery or can I just charge it when I want?

    Thx for your replies.

    Format the battery?
    Charge it when you want. It's not good to let it run all the way down to 0% very often, but otherwise, just wear it and charge it.

    I heard that sometimes some devices need to be discharge to 0% and then recharged. Battery capacity update etc.

    Think that was more the case with NiMH batteries. Li-ion batteries can be charged whenever.

    Charge when you want. Let it run down as much as you like.

    You will never actually get the cells to 0% as the watch realy has around 10% in the cells when the display says 0%. Its just how modern devices work.

    You will hear a lot about "Dont EVER let it get to zero! Dont charge to 100%" but that info is a half truth. True, you should never let a Li-ion battery get to 0 or 100 but YOU cant ever do that. The device will stop charging before it gets to the top and never let you run it all the way down. Now, if you somehow could bypass the built in battery management then sure, you can damage the cells. But you cant.

    Use it, charge it, enjoy it.

    This was for batteries with completely different chemistry.

    Just put it on the charger while sleeping and do not worry about the battery.
