    Explain.

    I have always used my devices while they are charging, just not extensively.

    How and when to charge your tablet battery - TechRepublic.

    Use while charging: Is it okay to have your device on while charging it?
    Lead acid: It's okay to have device on when charging.
    Nickel-base: It's always best to turn the device off during a charge, since a parasitic load can either alter full-charge detection, overcharge the battery, and/or cause mini-cycles.
    Lithium Ion: It's always best to turn the device off during a charge, since a parasitic load can either alter full-charge detection, overcharge the battery, and/or cause mini-cycles.

    I use it in my vehicle and I always have it plugged in. Likewise with my Samsung 4.2. I haven't seen any problem.

    I have a charger at my desk, one at each of my easy chairs, one in my car, and I'm always topping up and using while charging. I've done this for years with no problems.

    For li-ion that USED to be the case but they created protection circuits for just that reason. Here's a rundown by TI on how they use it but every phone/tablet uses it now. www.ti.com/lit/gpn/lm3641

    yes. i have read it online, it is best just to plug it in while using the laptop. but asus tech told me that it is better not to use it while it is charging.

    yes. the problem might be when you have it unplugged, then you will notice that the battery won't last long.

    ASUS just released some new charger stands for the N7 that are tilted to allow easy viewing while charging. I don't think they would do that if it really was harmful to use while charging!

    I don't believe it's harmful; if it was, tech sites would know about it and no one would be using their device while charging. Where are you getting that it is harmful?

    It isnt harmful to use this tablet while charging, although if you happen to be rooted and are overclocked it might warm up quite a bit so be careful if thats the case. Hope i was able to help out

    i used it while it was charging. for unknown reason, after i got it back for the 2nd repair, the battery started to decrease really quickly. i chatted with asus tech online, the guy told me that it is better not to use it while it is charging. i also chatted with a google playstore nexus 7 tech, he told me from his personal experience that it seems to decrease the battery power.

    Charging Lithium-Ion Batteries – Battery University

    A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.

    Here are three main tips that should easily apply to all batteries in mobile devices:

    Temperature: Do not expose your device to extreme temperatures. Cooler temperatures prevent battery corrosion, so it's always best to keep your device from overheating. It happens. Working with a tablet in your lap, you can feel the warmth heating up your legs. That means the battery is also getting hot. Work with your tablet in such a position that heat can easily dissipate. Discharge: It's a myth that modern batteries need a full discharge to retain "memory" (this only applies to a nickel-based battery pack). Every full cycle wears the battery down by a small amount. So, smaller discharges are better. Try not to let your battery go beyond the half-way point before applying a charge. Abuse: This is a no-brainer, but people do get careless, and every drop of that tablet runs the risk of damaging the battery within. This also applies to improper discharges. These types of discharges can happen when a process gets out of control and is allowed to continue on, which quickly runs down the battery. If you see this happening (if the tablet starts responding slowly), find the rogue process and kill it or restart the tablet.
    Let's look at some more tips on how and when to charge your tablet battery.

    First charge: When you first unbox your tablet, you should approach the first charge differently, depending upon the type of battery the tablet has:
    Lead acid: The battery should be fully charge. Apply a top-off charge before using.
    Nickel-based: Charge the battery 14-16 hours before the first use.
    Lithium Ion: Apply a top-off charge before the first use.
    Full vs. partial charge: Some batteries actually do poorly if you only give it a partial charge.
    Lead acid: You must always give this battery a full charge, as a partial charge can create sulfation.
    Nickel-base: A partial charge is good.
    Lithium Ion: A partial charge is actually better than full charge.
    Full discharge: There are types of batteries that actually prefer a complete discharge now and then.
    Lead acid: A deep discharge can damage the battery.
    Nickel-base: Apply scheduled discharges only to prevent the battery from retaining memory.
    Lithium Ion: A deep discharge can damage the battery.
    Battery calibration: Some batteries do not need calibration. Here are the details:
    Lead acid: Not applicable.
    Nickel-base: Apply a discharge/charge when the fuel gauge becomes inaccurate. Repeat every 1-3 months.
    Lithium Ion: Apply a discharge/charge when the fuel gauge becomes inaccurate. Repeat every 1-3 months.
    Use while charging: Is it okay to have your device on while charging it?
    Lead acid: It's okay to have device on when charging.
    Nickel-base: It's always best to turn the device off during a charge, since a parasitic load can either alter full-charge detection, overcharge the battery, and/or cause mini-cycles.
    Lithium Ion: It's always best to turn the device off during a charge, since a parasitic load can either alter full-charge detection, overcharge the battery, and/or cause mini-cycles.
    Unplugging when charged: Is it necessary to unplug your device once the charge is complete?
    Lead acid: This depends on the charger. If the charger has correct float voltage, then it's fine.
    Nickel-base: Always remove your device after a few days in the charger.
    Lithium Ion: This is unnecessary, because the charger turns off.
    Temperature: How does temperature effect charging?
    Lead acid: It creates a slow charge from 32-113 degrees Fahrenheit / fast charge from 41-113 degrees Fahrenheit / the threshold is lowered above 77 degrees Fahrenheit.
    Nickel-base: It creates a slow charge from 32-113 degrees Fahrenheit / fast charge from 41-113 degrees Fahrenheit / the battery will not fully charge when it's hot.
    Lithium Ion: Do not charge below freezing. Do not charge when above 122 degrees Fahrenheit.
    Of course, this doesn't take into consideration the effects of various types of software or networks (such as 4G, which will quickly drain a battery). Ultimately, if you use your battery with intelligence, it will reward you with a long life.
