How low should the battery get before recharging it?

    Preferably as dead as Elvis.

    Do NOT drain a lithium ion battery to 0%. That's one of the few things you can do to a lithium ion battery that may hurt it. Other than that, charge the battery when you need to. Charging it when it's at 70% or 50% won't hurt it. Lithium ion batteries have no memory effect.

     

    What Apple does recommend is, once a month, let the iPad battery drain until it shuts itself off, then charge it fully. This has no effect on the battery itself. It just calibrates the battery sensor.

    I charge my battery every single evening when I go to bed. It doesn't matter where the gauge is - 50%, 30%, 85% - I charge it every night. I did the same with my iPad original which is still going strong.

     

    Don't let it drain down to zero every time that you want to charge it. Charge it when it needs to be charged and use the advice that Meg posted about calibrating the battery gauge once a month.

    Can you clarify something for me? Letting the iPad battery drain until it shuts itself off, I would think that it would be to the zero mark then, or not? I've only let it get down to 10% and it didn't shut itself off at that point, so at what percentage does it shut itself off?

    And what exactly is the battery calibration doing for the battery (besides the obvious of calibrating the battery lol)?

    I'm eager to learn as this is my first iPad. And btw is the battery calibration good for the iPod touch and the iPhone also? Done in the same manner?

    Thank you

    You're overthinking this. The iPas will turn itself off when it turns itself off. It's possible to turn it back on and "squeeze" out a bit more battery. Don't.

     

    The battery is not calibrated. The sensor is. All this does is make the battery meter on the device more accurately reflect the amount of power remaining. It does nothing for the battery itself.  And, truth to tell, in all the years I've had iPods, iPads, iPhones, cell phones and other devices, I've never bothered to do this. They all have worked just fine with the battery lasting well beyond the warranty period.

     

    YMMV.

    But you've just stated a contradiction!

     

    "Do NOT drain a lithium ion battery to 0%..."

     

    and

     

    "What Apple does recommend is, once a month, let the iPad battery drain until it shuts itself off..."

     

    Same difference?

    Or did you forget to point out some time period factor that follows the "drain battery to 0% ?"

    Or is it something about the speed or stye of draining it?

    Reread the 1st paragraph of my previous post.

    Reread it yourself! What an arrogant reply.

     

    "do NOT drain" + "Apple does recommend to drain"

     

    Go figure.

    I apologize. I was assuming a certain basic level of reading comprehension and that was, apparently, a mistake. Here's the paragraph to which I referred:

    Of course you would prove your true arrogance. Pfff. Yeah it's MY reading comprehension!?! You show how utterly meaningless are your words and chaotic are your thoughts.

     

    Try looking up the word "drain" as in "Apple does recommend to drain power" before crying from your high horse. Say what you mean and mean what you say.

     

    And your italicized quote is hardly your 1st paragraph. It's not even your previous post!

    Hello,

    I couldn't help through I'm my two cense here, seeing as you jumped on Meg St.Clair when she was only trying to help.

     

    She said do not drain battery to 0%, then she said once a month Apple recommends to drain the battery until the iPad shuts off. The iPad shuts off before the battery reaches 0%, as do laptops to protect the battery.

     

    She then posted again further explaining this to katinak67 who needed more help understanding. She explained how the iPad shuts off when it sees fit, and when this happens, she explained not to turn the iPad back on and drain the rest of the battery (this would be draining it to 0)

     

    When she asked you to reread her previous post, she meant her second post, not her first. This is where you got confused, as you thought she meant her first.

     

    So it's you who needs to read a bit better and think a bit more before you start a war!

     

    MegStClair, your post helped me so much, so thankyou!

    @ Meg StClair TY!! I used my ipad until it shut off and was afraid I had hurt the battery when I plugged it in to charge and had no display. Happy to learn that it will automatically shut off BEFORE battery is hurt. Don't worry about comment up further some peeps just won't take the time to read before lashing out,
