My iPad Air (bought from Target) was completely dead when I opened the box. I didn't think much of it, other than that is was weird that a product just released would already be completely out of battery life. I;ve never had that experience with an Apple product. But I brushed it off, and said oh well. Then, after a complete charge (which took WAYYYYY too long imho), the iPad lasted for 3hr. 30minutes of light web browsing. I thought, "maybe the battery just needs to be calibrated. I let it completely die... then charge it up completely full again. Again, 8% battery after 2hr. 55 minutes of usage and 6 hrs. on standby. I was not a happy camper. I had to call Apple, cancel my Applecare+, then return the damn thing to Target. To top it off, they didn't have any replacements in stock. So I now have a Target gift card worth $507 (manager asked if that was ok, and I said sure b/c I assumed it would be as simple as me walking to the back of the store and getting another one). I don't blame Target for being out of stock. It is just frustrating to wait. So frustrating, in fact, that I may end up waiting for the iPad Mini w/ Retina or the PS4 (whichever is "in stock" first at Target). All that to say this: check your battery life on the new iPad Airs you are all enjoying.
