Device Detection for Apple iPhone and iPad

Which techniques to use and avoid

51Degrees data analysis team stress tested a range of real iPhone and iPad devices, both old and new using all the major web browsers in order to determine if CPU stress testing is a viable additional method to identify iPhone and iPad models alongside User-Agent analysis, screen information and WebGL API

The full results are available for download along with the analysis of the differences between each device and browser.

Apple Standalone on Device Detection

Exposing the crippling solution used to detect iPhone and iPad models

Device vendors as varied as the mighty Samsung, to brands like Pantech and Micromax all recognise the importance of identifying different device models when accessing web sites. However, Apple do not fully support this approach.

Some device detection solutions have tried to address the problem by artificially stressing the iPhone or iPad to determine how quickly its processor can complete iterative tasks. Understanding how the device performs under stress provides an indication as to the CPU available and therefore the model of the device. The approach can yield more information but ironically at the expense of user experience as the page load time increases and the battery is drained more rapidly.

If every web site were to stress iPhones and iPads to gain model information the web would slow down for Apple users. This isn’t in Apple’s interest. However, if Apple make a simple change the problem can be avoided.

Why Fast Device Detection Matters

How 51Degrees Beats the Competition

Detecting mobile devices is important as websites designed with large desktop computer screens in mind rarely perform well on a mobile device. Detecting such devices allows you to present content in the right fashion for the viewing device which improves website performance for your visitors and leads to better user experience. You will find many device detection products on the market and they all claim to be the fastest and most accurate but they do not provide proof. 51Degrees device detection solution achieves 99.97 percent accuracy with 5 million detections per second on hardware that costs less than 1000 USD which makes our solution the fastest, most efficient and hence most environmentally friendly. 51Degrees device detection is easy to deploy in PHP, .NET, Java, Perl, Python and C. In this article you will find test results for the 3 test hardware platforms we used as well as instruction on how to test our device detection solution in your environment in just 4 easy steps.

OTA13 - Jon Arne S: Mobile Web Performance

Mobile and web performance guru Jon Arne Sæterås' presentation was particularly informative, and inspired me to write a quick summary for people that did not get the chance to see it live in person.
