The new iPhone 5s looks a lot like the 5, but there are some key differences.
A cool scanner registers your fingerprint so just a touch unlocks your phone.
Consumer Reports found it works well and blocks everyone else.
And Consumer Reports' tests show the camera delivers better results for still photos in low-light conditions than the iPhone 5.
There's a faster processor on the iPhone 5s to improve graphics, and the new operating system, iOS 7, is more user friendly.
"Overall, while the 5s isn't a revolutionary step forward for Apple, at first look, it's an improvement over the previous iPhone with lots of cool features," said Mike Gikas, of Consumer Reports.
Apple also released the iPhone 5C Friday, which comes in several colors and starts at just $99. Consumer Reports will be putting both phones through a full range of tests.
