Ok, let's say I'm using my iPad at my office, from 10am to 6pm, I didn't leave my table, and is it safe to plug in my iPad into power adapter and use it for the whole office time even it is already fully charge? Or I have to unplug it as soon battery full then only use? Sorry for my English

Why would u wan to do that? I think it would make the battery life weaker after a long period of time...

that case your ipad going die very soon

dont charge it when it was fully charged, not good for the battery.

Why do u need to plug 24x7? Battery will kaput within a year. A fully charged iPad can last up to 2 days if u not watching movies or playing music. Mine is new iPad 4G, battery can last 2 days with normal usage.

Yea, i guess better don keep it charged all the time ( I mean every day for constant 8 hours where the battery is already full ).

BTW, is it ok i always charge my new iPad at around 30% left ? And i can only use it for 1 day ( after long time of 3G web browsing ) and at the end of the day left around 40-50% which i will charge it as i wan a full charge to start my new day.

By this, is it my battery will die sooner as well ? @@

what about using the ipad while charging? or do you guys leave it to charge 100% then only use it?

I don't think there should b any problem using it while charging but try not to overcharge it when it's already full..

Don't worry as the power will auto cut off once it full and will charge it once it's drained

Apple store got it charger 24/7

I usually charge my iPad before I go to bed and switch it off the next morning.....so.....

Advice?

I wouldn't mind charging it with 100% battery, if youre using it a lot , the battery is going drain pretty quick. sooner or later the battery is goin to be in weakening state with care or not.

so recommended to use the battery as low as possible before recharge?

as checked from battery information from wiki, there have some causes that may shorten battery life so called "Memory Effect"... beside laptop, i guessed better no to keep charge any portable devices all the time...

Apple Store charges their iPad all the time. I think that's fine lol.

My usage pattern, charge at night, use for the next day. Repeat.

It stops charging once its full so yes it's okay to leave it plug in. It's also better to use your battery till 20% then recharge. Do this once a month.

Guys, pls don mislead other user, go study abt battery first before comment, did u guys know this is 2012? Even nokia at 2006 already got the auto cut off when it fully charged , u guys stil stay on 2006 technology? Pls la it will auto cut off ur current, don believe? Try let ur connecter connect to ur ipad when fully charge, u will saw the percentage drop after certain time, after it detect at certain discharge level, the battery will auto recharge again. When charging ur ipad will feel hot, but after fully charge ur ipad wont hot even u stil plug with ur charging connector , mean it's not charging after fully charge.

It apply to same as u fill fuel at petrol station, it will auto cut the fuel to fill ur tank when it's full

my MBA remains the current flow when the indicator light turns green (fully charged) and yes, I am plugging it all the while when I am home with it. No harm to it, as when it is fully charged, it uses the current from a/c

Yes , what you're saying is true, after its been fully charged and your iPad is still connected , it will just use the electric instead of sucking up from the battery.

how do u we check the battery capacity for ipad? mac can use coconut battery.

Y u need to do that? Fully charged can last a week is not watching movie. I am using new ipad just for office normal working can last a week.

I usually use until drain only i charge, ipad battery is so strong what, dont need to charge 24/7
