According to reports, the 16e has a slightly smaller battery than the iPhone 16. 3279 mAh in the 16e vs. 3561 mAh in the 16.
Though, the youtube commercial states new internal design “optimized for new battery”.
IMO somebody just made that up based on it sharing the outer dimensions of the iPhone 14 which also happens to have exactly 3279 mAh. I can't really figure out what "larger battery" could mean in their release video if it isn't larger than at least the 14 if not the 16.
