He breaks these down as an incremental bump for the second generation iPhone X (2800 vs 2,715 mAh), a hefty 3,300-3,400 mAh battery in the iPhone X Plus and a battery up to 2,950mAh for the iPhone X SE. The aforementioned battery won’t use the same advanced technology which allowed Apple to squeeze an L-shaped battery into the iPhone X (something it will continue with the iPhone X Plus and second gen iPhone X). While some rumours have claimed a second generation iPhone X would drop in price to accommodate a larger iPhone X Plus, Kuo says this is not true. He claims the second gen iPhone X will again start at $1,000, the iPhone X Plus will be priced higher (likely $1,200-$1,350) while the once-cheap iPhone SE will see its iPhone X-inspired successor come in at more than an iPhone 8 starting from $700-$800. Were it to drop the price to $800-850 it would also risk the iPhone X cannibalising sales of the less fully featured iPhone X SE.
