Complain all you want about the Galaxy S4′s cheap-feeling plastic casing, but the device does have plenty of redeeming features that have nothing to do with its build. Popular United Kingdom-based consumer product testing website Which? over the past week has given the Galaxy S4 awards for being both the fastest smartphone and having the best battery life.In terms of speed, Which? says it put all major smartphone vendors’ flagship devices through its Geekbench 2 test that measures “processor and memory performance across smartphone platforms to provide a standard speed rating.” The Galaxy S4 came out well ahead of the competition in this test, as its Geekbench score of 3188 easily bested the second-place HTC One and its score of 2798.In terms of battery life, the Galaxy S4 scored the highest in both average call time with 1,051 minutes and average Internet use with 405 minutes. The Galaxy S4′s strong battery life is particularly impressive given how many features Samsung has preloaded onto the device.
