Well, to be precise, after running a test it's telling me that my iPhone 5's Safari browser is superior to only 35% of all smartphones with a score of 1500. According to them, an iPhone 5 should score around 2500. I cleared my cache as well as quit all my apps. I'm not sure if it's an issue with my phone or just the test itself, my browser seems pretty darn fast to me (I'm coming from an iPhone 4, though). Should I be worried or is there a reason for this that doesn't have to do with my phone?
