There’s a new set of TouchMark benchmarks from Agawi, a cloud streaming company. Agawi used a 240fps frame rate camera and a "Touchscope" (custom hardware). It measured the App Response Time (ART) of quite a few of the most popular smartphones. ART is the latency between a user touching the display and a response being shown. The lower the score, the more responsive the touch screen.
The iPhone range were the quickest: the 5 had an ART time of 55ms while the 4 had an ART time of 85ms. The fastest Android device in this test was the Galaxy S4 with a response time of 114ms, twice that of the iPhone.
This doesn’t really make a difference in regular usage like opening applications; however, when typing on an on-screen keyboard it will be noticeable, more so if you’re a fast typist. If you’ve found the iPhone keyboard to be snappier than keyboards on Android devices then it’s not a placebo; it’s actually more responsive.
