If you read the comments to smartphone reviews, you will find comments maligning the use of the SunSpider benchmark. There is nothing wrong with running SunSpider benchmark on a mobile phone. It is the way it is used. Using the SunSpider benchmark to declare a phone as the fastest in the land is erroneous.
SunSpider benchmark results are used out of context
Still, does this mean that it is not a good test of smartphone performance?
The SunSpider benchmark is not a hardware stress test
I conducted some SunSpider 1.0.1 tests from an Apple iPhone 5 and Samsung Galaxy S4 i9505. Here are the SunSpider benchmark results I obtained from these two phones: (Lower is better.)

SunSpider optimization is not a bad thing
Some reviewers have started saying that SunSpider is not a useful smartphone benchmark because it has become the target of optimization. There is nothing wrong with smartphone manufacturers, or more specifically web browser developers, in optimizing for better SunSpider benchmark performance. That is why the benchmark was created in the first place.
