    Newbie question - will using the iPad plugged in make it last longer?

    I've replaced batteries on my ThinkPad computers (the oldest one was made in 2002) and this is my first tablet. I understand the end user cannot replace the battery, and I'm using it a lot, re-charging it every couple of days.

    I wonder if using it plugged in would extend the life of the battery or cause the iPad to run too hot causing a different problem? (Or anything else I'm not thinking out loud about).

    Of course, I realize using the iPad with the cable attached it less convenient.

    Thanks.

    Bob

    There's no harm in using the iPad as much as you want while it's plugged into the charger. Even when the iPad is plugged in its running on the battery, which is kept topped up by the charger. The lifetime of the battery is based on the number of full charge cycles it undergoes. I think it would take quite a bit of use while plugged in to equal one full charge cycle.

    Thanks. That's what I suspected, and my search on the forum turned up too many hits that had nothing to do with my question. I obviously didn't know how to use the right combination of search terms to think the noise out of the answer.

    You can't overcharge an iPad battery. Leaving it plugged in will not harm the battery. The charging circuitry knows when the battery is fully charged and will go into a maintenance cycle of small discharges and trickle charging.

    iPad batteries work different, as scifan57 told you. You can't overcharge them, and auto cut won't harm them either.

    Well, I believe that you need to educate yourself on modern lithium ion battery technology - two of our experienced posters have already made statements contradicting your comments. Quoted below is a list of the pros & cons for this battery type (put together from several web-based articles over the months).

    As already stated, Li-ion batteries have built-in circuity to sense temperature, charging state (and tract cycles), voltage regulation, and 'shut-down' steps if overheating is an issue. Now these batteries can indeed overheat, expand, and have even 'burst into flames' (an extreme rarity - "It's not very common -- just two or three battery packs per million have a problem -- but when it happens, it's extreme." - Source).

    So, the bottom line is that Li-Ion battery technology is safe and having the battery plugged into a computer or i-Device will not under normal circumstances harm the battery nor the device. As an example, I keep my MBPro laptop plug into power probably 99% of the time - has been going well for 2 years w/ just over 200 cycles used & 93% battery health - Dave :)

    I gig as a musician and use ThinkPad computers exclusively. I'm not a brand snob but the advantage of using Windows is that if both my main computer and my spare go bad on the same day, I can go to any store, pick up a replacement, put my flash drive in and make the gig.

    I use ThinkPads because they are bulletproof. The oldest ThinkPad on the sage was purchased in 1992. Back in those days, about an hour on battery is all you can expect. I always use it plugged into the AC, and today, 13 years later, it's still running but only has about 20 minutes battery time. I could replace it, but really, I don't need that much. If the power goes out, the PA isn't working anyway, so I only need enough time for a safe shut-down.

    I was hoping the batteries and charging circuits on the iPads were similar.

    I'm looking at some music software that I might want to play 'in real time' on stage, and if that's the case, I'll keep it plugged in like my ThinkPads.

    Thanks again,
    Bob

    I agree but it's still advantageous to let the battery cycle down a few times here and there for accuracy and just to "work" itself once in a while. I don't have any scientific data to back this up, just the way I see it.

    My Airs battery still works like a champ and I charge it when needed but don't leave it plugged in all the time.

    Cycling down the battery doesn't improve battery life. It just helps the phone/tablet predicting more exactly how long the battery will need until it's discharged again.

    What you should do with Apple's batteries:
    Recharge them frequently.
    Don't let the battery run down below 20 - 30 %, if possible.
    Allow it to recharge partially.
    If you need a more accurate estimate of the remaining charge, run down the battery until it cuts off, do this once a month, or even less frequent.
