Usability

Performance
As with any computer system strong performance is paramount. Under-powered smartphones cannot only impair productivity but also seriously test your patience.

Connectivity
The ability to connect to the internet and other devices is one of the hallmarks of smartphones. The highest rating devices include 3.5G data speeds, Wi-Fi, GPS, Bluetooth and USB connections. Those with lower scores include varying combinations of these options.

Features
Similar to basic consumer mobile phones, smartphones can include a range of useful features, but rarely does a single device include all sought-after features. The list below ranks the smartphones with the best collection of sought-after features.

Value for money
Perhaps the most difficult criteria to evaluate, value for money takes all other criteria into consideration and compares this result to the recommended retail price.

Editors' rating
Our editors' rating not only compares the basic criteria and value for money, but also considers the market the smartphone is released into. With technology changing rapidly our editors' ratings act as a barometer of value that is otherwise difficult to assess based on specifications alone.
