Nokia Lumia 928 lags far behind the iPhone 5 in new screen latency test
A new test developed shows Apple far ahead of Android and Windows Phone for reduced display latency
When it comes to smartphones, screen response time is one of those key features that helps ensure a great user experience. Some of you may recall the use of resistive touch panels on smartphones years ago and how slow those were to respond to touch. Capacitive displays are certainly much quicker, and it’s the reason why touch-typing is so common today, having been accepted by the masses.
The question for one company though is how to measure that display latency i.e. the time it takes for the system to detect and register a touch, thereby launching an app. App streaming company Agawi has come up with a solution called TouchMarks to make accurate and quantifiable measurements in this area and the Lumia 928, while not the worst, is far behind Apple.
Devices compared include the iPhone 4, iPhone 5, Galaxy S4, HTC One and Moto X in addition to the only Windows Phone, the Nokia Lumia 928 found on Verizon. From the write up:
Indeed, the Lumia 928 had a response time of 117 ms whereas the iPhone 4 was at 85 ms and the iPhone 5 was even better with an extraordinary 55 ms response latency. The iPhone 5S, released this past weekend, had yet to be tested.
Why the discrepancy? Agawi has their theory:
The results are fascinating, and while we can debate whether or not that extra 50 ms would really make a difference in user experience, it seems Apple has once again bested Android and Windows Phone. Microsoft is aware of this problem though as noted in the above video, where Microsoft Research is working on 'High Performance Touch'.
Agawi has open sourced the hardware and software behind TouchMarks, so people can peek at what they are doing (and try to replicate the results). The company also plans on doing future tests on other devices to see how they stack up, including the new iPhone 5S. We hope those future tests include different Windows Phones too because for all we know, the Lumia 928 is the exception and not the rule. Still, it seems clear that Apple has spent some time considering this area in engineering their phones.
Will these results cause companies like HTC, Nokia or Samsung to reevaluate their approaches to screen calibration? We hope so as this is one important area that manufacturers won’t want to skimp out on.
