Mine charges in about 5 to 6 hours which is pretty much the same amount of time it took for my iPad 2 to charge. Be sure you do a full discharge and then recharge for at least one or two cycles and the battery life should be what you're looking for, about 10 hours. Issue with people only getting like 5 to 7 hours of battery time is because they have the brightness at max and all the antennas turned on when even Apple doesn't do their test at full brightness. I think it's Engadget.com the does the battery life tests in the past and the even do their test with 50% brightness, LTE or 3G turned off, Wi-Fi only, maybe Bluetooth on and all the did was loop a movie over and over again until the iPad dies or whatever tablet they happen to be testing. I don't know if they've actually tested theiPad 3 yet, I'll have to take a look at their website, but I am sure they're going to probably come up with the same kind of results, 10 to maybe 11 hours of video playback.

Almost 10 hours of video playback on 50% brightness and LTE/HSPA+ on. If Wifi only was used I am sure it would be over 10 hrs
