Game Of Thrones Season 6: 8 Ways Battle Of The Bastards Will Be Different In The Books

This one isn't particularly related to plot differences between the show and the books, but rather how the battle is filmed and unfolds.

Jon Snow is the character that grounds viewers in the battle, as we follow him from the very start of it, and then track his fighting through it, before he almost gets trampled in that horribly suffocating scene.

That scene, though, was added quite late in the day. Miguel Sapochnik has confirmed that the original plan, as written by Weiss and Benioff, wasn't manageable in the amount of time they had, and that's what he came up with instead (safe to say it worked, because it's a great sequence).

That means it was already different from how Weiss and Benioff had planned it out, which in turn was probably somewhat different to how it'd happen in the books. It means the actual mechanics of how the battle unfolds will change considerably, as Jon won't be getting trampled, and that in turn changes the events leading up to the moment, and what comes after.

Also, of those involved in the battle, those with point-of-view chapters in the books are Jon, Davos, and Melisandre. Given Mel won't be involved in the fighting, her chapters won't shed much light on the actual fighting, meaning it'd all be told from the perspective of Jon and Davos (that's going with the idea that Stannis dies and he joins Jon, having safely made it back from Skagos) - unless new characters are given POV chapters in The Winds of Winter - which would be a different way of seeing it unfold.
