A scratch- and crack-resistant sapphire-glass screen is the feature that’s most wanted in the iPhone 6, said a survey of 1,000 smartphone owners done by uSell.com, which bills itself as the leading online marketplace for used iPhones. Of the respondents, nearly half (45.5 percent) see sapphire glass as their most desired iPhone 6 feature, followed by an infrared camera that can see in the dark (19.2 percent) and new tools for monitoring health and fitness (10.7 percent), it said. Only 9.5 percent want 3D functionality in the iPhone 6, and only 7.7 percent want smart home tools to control their home appliances, it said. The survey also asked respondents which incremental iPhone improvement they would want most in an iPhone 6. Longer battery life topped the list (37 percent), followed by a bigger screen (19.2 percent), it said: “Even though a bigger screen is a much talked about iPhone improvement, nearly twice as many people consider improved battery life to be more important."
