Touchscreen Latency
Dean Takahashi (via John Gruber):
In its first TouchMarks benchmark test, the iPhone 5 responded to touches at an average time of 55 milliseconds, compared to 85 milliseconds for the iPhone 4. The closest Android device was the Samsung Galaxy S4 at 114 milliseconds.
Jens Andersson (via Hacker News):
Well, for one thing we can see that the gaming-devices consistently outperformed the smart-phones. I can only guess why, but it is possible that the Nintendo 3DS and the PSVita can have lower latency since they will never have to render anything on top of your game like a phone sometimes do. Also, the input handlers are usually very effective on game-devices, allowing you to read the latest available input rather than have to wait for it to be sent to you through an event-handler like you have to on iOS and Android.
He measured 81 milliseconds for the iPhone 5 vs. 23 milliseconds for the Nintendo 3DS and just 9 milliseconds for the Nintendo DS.
