It is built into the chassis at the bottom of the display.
iPad has a larger battery so it lasts longer on avetage
yes at the apple store get an external battery for your iPad 2 may be the right choice, like mophie, mili, etc.
The Apple iPad 2 is said to have a battery that lasts for 10 hours on a full charge. Unfortunately, the battery life does decrease over time, so to delay this decay, make sure that you are properly charging your iPad 2. After a full charge, use the tablet until its battery indicator shows a red status, indicating that a charge is necessary. By constantly charging the iPad before its battery is this low, you'll be speeding up the aging of its battery.
This will be marked on the label on the iPad and its original charger.
No because the iPad 2 is to highly advanced with the two cameras and Intel core duo 5. But you can get the software update IOS 4.3 on you Ipad. It should be up as a download on itunes for free in a few days from March 10 2011. Umm no actually you can they will give you money for the trade and then you can buy the iPad 2:)
It's faster, has more battery and you can talk/text!
Depend on the settings in some case yes.
. The iPad can last 15 hours or more
The iPad mini with retina display has a battery life of 23.8 watts per hour.
Depends on your definition of removable, you can remove it, just not as easily as most devices, instead of there being a screw to take out or a button to press, you actually need to work yourself into the body of the iPad and solder the battery in/out...
Electronic devices usually have a battery or dry cell that stores some energy. In the case of the iPad, the battery is rechargeable.
Alright, I will suggest everyone to get the iPad 2. This is because it is lighter and you are very sure that it will give you 10 hours of battery life. As for the new iPad, you are not sure because it contains an A5X chip which makes it faster for battery usage. So think again, they both have good and bad things. My opinion is that iPad 2 is better!
