I finally upgraded my iPhone from the 4S to the 5S. Overall it looks like the 5, but the new features are pretty cool and from hearing about bad battery life from my friends on the 5, it most likely has been increased as well. It is definitely better than my 4S’ battery life.
So far, I’ve mostly played around with the camera. It is substantially better than previous ones and has much better low light capabilities. Video is now 1080, but doesn’t benefit much from the low-light lens. Here is a video I took of my friend’s cat. I slow-motioned it at the point the kitty dives off the counter chasing a laser.
Compared to previous iPhones, it also seems quite a bit more responsive. The new TouchID is awesome, but I found that if you work your hands and get minor cuts or abrasions, the sensor can have a hard time distinguishing your prints on those fingers. Also after washing dishes, it had a hard time probably due to “granny” fingers from the water.
I would recommend this phone as a good upgrade if you’re out of contract or on a 4S or below. 5 users may want to wait for the next iteration if they are happy with their current phone.
