The load characteristics also matter. Under certain load profiles those AAAs won't come even close to their rated capacity (no matter what misleading unit used). I also find the 1.9wh very optimistic, I guess you took the average AA capacity, in which case the battery would almost become bigger than the phone.

1.9 seems like a typo as 12/1.9 is 6.3, nowhere near 10. 800mAh seems to be a pretty available capacity and yields 1200mWh which tracks with the factor.
Though I think I’ve seen up to 1200.

1.9Wh was the number I saw on Google. 10 was just me not thinking clearly late at night. I updated my comment.

Load characteristics do complicate things as well, but I figured even the optimistic case involved enough batteries to dissuade anyone from this idea.
There are other non-rechargeable chemistries that are far more energy dense than AAA batteries, and those might be interesting to discuss.
