I thought that these new batteries didn't have memory so it wouldn't matter if you left them plugged in all of the time.
I'm not at all worried about the battery life. The device is said to keep at 80% for 1000 charge cycles. That is about 10,000 hours of use no matter when you charge it.
bobob said:Wouldn't that be a range of up to 10,000 hours?
If you chose to use your 1,000 charge cycles after only two hours of use every time, then the lower end of the range would be 2,000 hours of use (still a lot of time!).
I tend to think of it as 1,000 days, or almost three years of daily charging - - or just in time to buy the hot new 4th generation iPad in 2013!
The only advantage of a removable battery would be to ensure you don't run out of power on a 8-12 hour plane flight.
The downside of a removable battery would be the extra two layers of plastic it would add to the thickness of the device, not to mention the bulk added by a battery latch and a docking connector for it. I like the thickness the way it is.
By the time your ipad's battery dies, you will probably be ready to buy the iPad 2G instead of forking out $100 for a new battery.
Actually a charge cycle is defined as the total amount of depletion of your battery, regardless of when you charge it. So, if you use 25% and then recharge it, and do that four days in a row, you will have used one charge cycle. I believe Apple actually has this somewhere on their battery information page.

Standard Charging
Most lithium-ion polymer batteries use a fast charge to charge your device to 80% battery capacity, then switch to trickle charging. Thats about two hours of charge time to power an iPod to 80% capacity, then another two hours to fully charge it, if you are not using the iPod while charging. You can charge all lithium-ion batteries a large but finite number of times, as defined by charge cycle.
Charge Cycle. Using and recharging 100% of battery capacity equals one full charge cycle.
A charge cycle means using all of the batterys power, but that doesnt necessarily mean a single charge. For instance, you could listen to your iPod for a few hours one day, using half its power, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two, so you may take several days to complete a cycle. Each time you complete a charge cycle, it diminishes battery capacity slightly, but you can put notebook, iPod, and iPhone batteries through many charge cycles before they will only hold 80% of original battery capacity. As with other rechargeable batteries, you may eventually need to replace your battery.
I've read through the iPad battery recommendations from apple. http://www.apple.com/batteries/ipad.html
Besides the recommended monthly full charge cycle routine, is it best to use my iPad until the battery is lower, say 20% then recharge or just recharge when its not being used? (90% 96% 82% or whatever). I have a tendency to plug it in every time I'm not using it thus my obsession with battery 100%. I tend to stockpile items from Sam's Club, too.![]()
Lithium or Nickel (Li- or Ni-).
- Nickel batteries only want to be charged about once a day for heavy use. Charging Nickel batteries multiple times a day will destroy them in a very short time. Nickel batteries are said to have a "memory" because they are designed to remember the feeling of zero charge, not the actual state of zero charge. Don't lie to it, just plug it in when it's dying or dead. Let it use its memory. A full charge on Nickel batteries gives more "battery time" vs Lithium.
- Lithium batteries want to be charged the same, *but* they don't prefer FULL charges (from zero to 100). They prefer to go from anything but zero to 100, but only once *or twice* a day - they don't really have that memory thing down in Lithium. A full charge on Lithium gives less "battery time" vs Nickel.
Follow these rules, with any device, and you're good to go. I prefer Nickel batteries in laptops, and Lithium batteries in cellphones.
I used to be obsessive about keeping my iPad at 100%, so I just turned the percent display off and my life has been better ever since.![]()
Here's how to solve the problem:
1) Turn off the battery percentage indicator. It personally makes me too conscious of the battery, when in reality the battery lasts so damn long I never have to worry about it. Staring at the percentage left is silly.
2) Plug it in when it is low and whenever you go to bed.
That's all you have to do. Stop worrying about the battery, it will only drive you insane. There is no such thing as overcharging with Lithium Ion batteries, and every battery has a finite life time. If you are concerned about the battery losing capacity over time, buy AppleCare or simply pay for a battery replacement whenever it happens.
The more you worry about it, the less you will have time to enjoy your awesome iPad.

Don't Worry, Be Happy!
Birds are meant to fly,
Fish are meant to swim,
SUVs to roll over,
And....
The iPad is meant to be used!
That high capacity battery is there for your personal convenience and satisfaction!
It absolutely DOES NOT require pampering or carefully planned maintenance. Just Use It! Charge it to 40%, 70%, 100%..... it won't matter all that much in the end.
By the time it starts to falter in the far-off future, you'll be happily using the 3rd, 4th or 5th generation iPad Pro.
Have a little faith in Apple's engineering. They wouldn't have made it non-replaceable if it was at all likely to fail until well after you no longer care.
