...at least that is what this random anon on twitter seems to believe.
I think the 2,775 mAh will be destined for the 5.4", the 3,687 mAh for the 6.1", and a yet-to-be-leaked 4,400+ mAh will find its place in the 6.7". I don't know why the 2,227 mAh was thrown into the mix, but perhaps it's meant for another device entirely. Maybe a more souped-up variant of the SE? Who knows.
Edit: Another tweet
