How long should you leave your iPad 2 on for it's first charge

how long you your iPad be on for it's first charge

You don't have to charge it up to 100% on the first or every charge, nor run it down to empty everytime before you re-charge it. This page just recommends going through at least one charge cycle per month :
For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

  • How long should I leave my Hp pc on for?

    hi i have an hp p7 1245 and i leave it on for about 12+ hours a day. is it safe to leave it on for 30 hours straight? 

    Hi,
    Actually many computer can run 24/24, non stop.  As long as you keep it cool, you can leave it running 30+ hours. It knows when it goes to sleep anyway.
    Regards.

  • How long should it take my iPad to charge

    How long should it take my iPad to charge?

    What model iPad? 1,2,3,4 or mini? When you ask a question, you need to provide enough info to answer.
    I assume you mean from near 0% to 100%.
    Depending on the model, it takes 3 to about 8 hours.
    The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
    How to Calibrate Your Mac, iPhone, or iPad Battery
    http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

    In rare instances when using the Camera Connection Kit, you may notice that iPad does not charge after using the Camera Connection Kit. Disconnecting and reconnecting the iPad from the charger will resolve this issue.

  • How long should I leave my iPhone in rice?

    My younger sister accidently spilled water on my iphone 4. It seemed okay but it kept trying to turn itself off so I put it in rice and its been in there for about 3 days now. How long should I leave it in there to insure that it will be OK?

    you can't be sure if it's ok
    But three days should do the trick. Good luck

  • How long should you use the Macbook is the fan is at Max?

    Hey all, the reason i ask is because sometimes when i visit a site with embedded video the CPU rises and heats up so the fan goes up to max. How long should you keep there with out damaging anything? Sometimes the videos are 45 mins, there tv shows and by 5th min is heated up and i dont want to keep it running for the rest of the 45 mins and wreck somthing. Whats the max time for that?

    Not really an answer but I was wondering where your computer is located or how you are using it? My kids were putting a quilted blanket on their lap and then running their notebook on top of the blanket. The blanket had a terrible insulating affect on the computer. And to make matters worse, sometimes the blanket would block the fan exhaust! I had to scold them and teach them to put something else on the blanket over their lap, like a book, and then put the notebook on the book. That really stopped the fan from running a lot.
    It's just something to be aware of. The MB will run cooler if there is space all around it.

  • HT4859 How long should it take to back up iphone for the first time with about 6 gigs?

    How long should it take to back up iphone for the first time with about 6 gigs?

    Welcome to the Apple Community.
    The first back up to iCloud may take some considerable time. Just how long isn't really possible to say without knowing how much is in your back up and your connection speed.
    What many people don't realise is that upload speeds are often significantly less than download speeds, so for example a user may have a download speed of 40 Mbps, but only 1 Mbps for uploading. As a rough guide it will take around 2 ¼ hours to upload 1 GB of data at 1 Mbps.

  • How long should you charge your new iPhone before using?

    How long should I charge my phone before using?

    There is no required charging time. Use it and charge it when its convenient.
    You should however not let it drop below 20% charge too often.  Once a month is suggested to re-calibrate the battery meter.
    Other than that charge and use as you like.

  • How long should I leave on?

    If I'm downloading files which are going to take days, is it safe to leave my Powerbook G4 on, while on charge? What's the longest this should be left on?
    Many thanks
    L.Dudley

    It's perfectly safe to leave your Powerbook on indefinitely, provided that it's connected to AC power, and it's given plenty of airspace around and particularly underneath it to enable it to cool itself as needed.
    What sort of download are you embarking on, that's going to take several days? If I were you, I'd certainly look for an alternate way of obtaining the file(s) rather than expect my internet connection to hold up without interruption for that long.

  • How long should you be able to use battery power?

    Here's the article on how to calibrate your battery:
    http://support.apple.com/kb/HT1490
    I don't know if you will be able to calibrate your battery successfully at this point or not. If you can, it will likely look even more unhealthy.
    Sadly, I think your battery is on its way out. As Retired Engineer points out, it hasn't had enough usage for optimum performance at only 69 cycles in close to 3 years. They also will deteriorate over time, whether or not you calibrate them or use them properly.
    You might find Battery University an interesting read:

    Also this kb article from Apple:

    I don't think there is any way to bring this battery back to health. Unfortunately, the cure is going to be a new battery.
    Good luck!

  • How long can I leave an iPad on?

    I'm tired of looking for a decent digital photo frame to hang on my wall. So I was thinking about turning a few of my old iPads into photo frames and essentially leaving them on all the time. Is it ok to leave the iPad display on all the time? Is it designed for that?

    Don't think they were designed for that. But if they're 'old extras' just lying around, why not use the no cost option you have? Worst that'll happen is that it fritzes out.
    I do have to say, I don't think ANY electronics are meant to be 'always on'. Everything has a finite life span and the way you use it can determine what that lifespan is.
