And not just better - but rocking a newer version of the iOS that uses less battery power.
This one's a shade more obvious than others: Apple's handsets will always come with a new iOS, and incremental battery improvements are standard practice across the phone industry.
But an oft-voiced complaint is that smartphone batteries just don't last the distance any more, draining the wrong side of 24 hours.
Number one on our wishlist of iPhone 7 improvements would be a battery that could support all the new features Apple makes its adverts about, and has a battery that lasts more than a day.
You've got the power to make it happen, Apple.
