> but smaller phones have less room for a big battery The nice thing about the SE form factor is that it is enough thicker than the 6 and later form factor to offset much of the battery concern. If they made an SE form factor phone with an OLED display (thinner), kept it precisely as thick overall, and shifted even more of the circuitry to the chin and forehead of the phone, then they could get a pretty big battery in there, and as a bonus, the OLED would generally be more efficient as well.
