I used one for hours yesterday browsing, a couple hours playing Lumines(a game that is said to kill phone batteries), Spotify running most of the time, an hour air playing to an Apple TV, an hour watching Youtube, twitter etc and this morning after another hour of Lumines I'm at 50 percent battery life. So I don't have exact numbers for you, but to me it's looking really really good.

Apple iPad (2017) review: Battery life
One area where Apple has not compromised, though, is the battery. The new iPad has the best battery life we’ve seen on any recent Apple tablet, and even on Android you won’t find anything better.

Apple quotes the iPad as having ten-hour battery life, as it does with almost every model. However, our standard battery test delivered 14hrs 47mins of performance, which, compared to 8hrs 56mins on the 9.7in iPad Pro, 9hrs 32mins on the iPad Air 2 and 12hrs 9mins on the Samsung Galaxy Tab S2, is fabulous. This is more than “goes all day”; this is “take it away for a weekend and you might not have to charge it” territory.
