Is it bad for IPad Pro to be plugged in 24/7

    I have been using my ipad pro as a wacom tablet and I have it plugged in ac power 24/7. Will this damage the battery long term or is it like a laptop that charges until its full then stops charging. I like keeping it plugged in all the time but I am wary that it will destroy battery life by doing so.

    The other thing I wanted to ask was I noticed they had some cheaper lightening cables (amazon basics) that say they are apple certified on amazon. These should work ok then if they are certified by apple?

    I use 6ft AmazonBasics Lightning Cables (much more durable than the Apple cables) and have had no problems. As for battery, being plugged in continuously isn't particularly good for longevity even with circuitry that prevents overcharging. That said, battery life on iPads is insanely good that even if you do so, after a year, you'd probably still be able to get a whole workday's worth of battery life for undemanding workloads.

    My devices always stay plugged in when I'm at home and not using them so they stay topped up if I need to take them out and I've never had an issue.

    Regarding Amazon cables - I use several of them and they work just fine. The newest ones have reinforcement at the ends, making them more durable. You can't beat the price - $7.99 for a 6' cable.

    It is recommended that you use one entire cycle (full discharge) at least once every 3 months.

    It'll stop charging when it's at full capacity. If it were to drop slightly below that it will trickle charge back up to capacity again.

    You won't damage the device or the battery by having it constantly plugged in. Indeed the worst thing to be associated with modern battery technology is quite the opposite, leaving your iPad stored for an extended period of time with no charge whatsoever can lead to a low discharge state and prevent it from ever holding a good charge.

    The days when it was necessary to cycle batteries primarily for their own health are long gone. However, if you do plan on using your iPad untethered you should allow it to completely power cycle every month or two for other reasons.

    While nothing to do with the condition of battery itself, the way in which a batteries remaining charge is calculated is affected. Over time, with multiple partial charges, your device ends up with whats referred to as a digital memory effect. While in no way harmful, this does affect the ability of the software to accurately predict the remaining battery power. Completely discharging and then fully charging the device afterwards allows the software to recalibrate itself and report more accurate battery levels.

    My suggestion is: you don't need to connect the AC power all the time unless you are doing high performance consuming tasks such as watching video, playing game because those task will possibly cause damage to the battery. Connecting the AC power all the time will hurt the battery health, you can unplug it when the battery is full and charge it when the battery remains around 30%.

    no. as long as the power supply is fine, leaving it in has no disadvantages

    High performance tasks do not damage your battery. Obviously they drain it faster so you will go through more battery cycles, but I wouldn't say that they harm the battery.

    Keeping your device plugged in all the time won't really harm the battery either, although it is good to give it some exercise and let the electrons flow from time to time in order to maximize its lifespan. I don't know that it makes a big difference though. Apple products seem to last a long time before suffering noticible battery decline.

    I've always wondered what "full discharge" meant. Do you mean to let it drop to zero? If so, would that mean a loss of data on the device? (Note: I've never let it drop to zero, precisely because of this (possibly unfounded) concern.)

    Any clarification of what "full discharge" specifically means (and its consequences or non-consequences) would be appreciated.

    Thanks!

    By "full discharge" I meant one entire battery cycle. For instance, if you discharge 50% today and another 50% tomorrow, you have a full cycle. No worries, you won't lose any data with data.

    No, letting you battery fully drain will not cause you to lose data stored on your device. That would really suck and screw over a lot of people who forget to charge their devices.

    Full discharge just means let the battery run down till the device turns itself off (really never goes to zero and if it did, it would likely damage it). And no you will not lose any data because of this.

    Leaving battery at 100% is bad if it also heats (say anything with heavy processing) or you're in a place with much environmental heat (outside in the summer).
    Heat and full charge is BAD.

    If you're going to do that, it's better to unplug and use it at it does it's heavy processing as it discharge until it hits about 40%, you can then plug it back in.

    Most uses though are not heavy processing, so it's not that bad; maybe let it cycle one in a while.

    They don't have memory, but the OS can sometimes lose track of it's charge level, which makes the battery seem to reached zero, or be fully charged when in fact it's not close. Doing a full cycle helps the OS to calibrate the zero again.

    Heat and batteries don't really mix well, so that's something to be avoided at all cost.

    Same here.

    I do this so if the electricity goes out I have a fully charged iPad and iPhone!

    So it sounds like you are saying if you leave your house, for say on vacation, there is some level of risk keeping a newer apple device plugged up?
