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.

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!
 
I top mine off also quite a bit ... I think it is from the lackluster battery performance I get on my iphone (jail broken ... Running edge ... And being a power cell user)

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. That’s 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 battery’s power, but that doesn’t 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.
 
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.

or you could just go and get an external battery pack for the same price of what a 2nd removable battery would cost if available.

Thank-you for taking the time to dig up the facts!
 
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.
 
It all comes down to...

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 let my battery discharge the first day I had it. I watched movies, downloaded apps, surfed. I started playing with it at 9:00 a.m and shut it off at 3:00 am and it still had 7% battery life. I would say I used it for sure 15 hrs. That 7% took another hour to run down the next morning. My husbands lasted the same so mine isn't a one off and he was using his in work all day. iPad ROCK :D
 
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. :rolleyes:

I am ordering the ivyskin iPad case that is also a backup battery pack. So, my iPad will last 20 hours. yay!!:)

Soo what type of battery does the iPad have? NVM didn't read other posts...d'oh
 
Don't know if it makes any difference but I've had iPhones (the original and a 3GS) for 3 years and I always kept them topped off. I too like to see a full-charge. Both ihphones are still in use (my spuse has my original) and both have no battery issues.

With the iPad I use it every day and then I re-charge it every night. Right now I am at 59% with at least two kore hours of usage ahead of me but some nights I'm only own in the 60s or 70s. I still re-charge.
 
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. :D

+1. This is good advice.

Ok, battery percentage display off! Great advice.

I concur with this...and I have done quite a bit of research of the discharge rate and charging preferences of batteries.

Lithium Polymer (most cell phones) are even different from Lithium ION. The newer, Lion Poly do NOT like to be deep discharged.

Like others on this thread, I am obsessed with the battery...but that is because I am clocking in easily 5-8 hours on the ipad...which includes going to bed with the iPad and staying up way too late at night.

The stress is when to charge. Fortunately, when I dock it at work (school) it's status that it isn't charging is at least getting a trickle charge so that by the end of the school day, it is back to 100%. But on non school days, it is a little more confusing.

I have next to my bed a clock designed for an iTouch. I am a little disappointed in my purchase decision because I JUST bought these two matching clocks for our iTouch. Since I have cats in the house that like to chew wires, I bought the clocks so the iTouch could not only charge on a base (no wires sticking around) and the radio has a recessed area for the iTouch to sit. There were others that I could have chosen that would have allowed the iPad to sit there and charge...but I specifically obsoleted my clocks by picking one that protected the iTouch.

So, anyway, I have to figure out how to rig up a charging station next to the bed I suppose and that will be the end of this challenge.
 
OMG!!!

Why make it so complicated?!?

Just plug it in before you go to sleep and that's the end of it!!!
 
The battery life on this thing is out of this world. I wanted to see if I could wear it out using it all day. Was surfing, listening to music and watching movies all day. I finally got sick of it and had to have a three hour movie play, while I wasn't watching it to finally get it to drain. Amazing.
 
By not draining your battery and then recharging it occasionally you're helping your battery develop charge memory which will lower the capacity of your battery over time.

Your obsession is going to cost you further down the line.
 
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.

I have read so many differing opinions about battery maintenance. I plug my phone in every night, whether fully drained or not, and i have not noticed any noticeable drop if the amount of charge the battery holds.

Use it and enjoy it!
 
I think the problem is that everyone is so used to their iPhone batteries running out so quickly that they have built up this unnecessary need to recharge constantly. When I use my iPhone, especially browsing the web, its battery goes down very quickly, but the iPad has a MUCH bigger battery and I am often amazed when I look up at the charge %. Everybody just needs to chill.
 
I'm quite worried about my battery. I charged it overnight so this morning it was fully charged. I've only used it for maybe 2 hours today and it's at 32%.
Bluetooth off, location off etc.
It seems to go down maybe 10% in about an hour when I'm not using it.
