People buy smartphones for all different reasons but it seems that having a strong battery has become the top reason for many buyers. IDC analyst Francisco Jeronimo has posted a chart from a recent IDC survey showing that 56% of Android buyers, 49% of iPhone buyers and 53% of Windows Phone buyers said that battery life was a key reason they bought their particular device. In this way, battery life trumped even ease of use, which 33% of Android users, 39% of iPhone users and 38% of Windows Phone users said was a key factor in choosing their smartphone. Interestingly, just 25% of Android users, 19% of iPhone users and 23% of Windows Phone users said that their device’s camera resolution was a major factor in their decision to buy their smartphone, which means that Nokia probably didn’t win over too many converts by heavily hyping the 41-megapixel camera on its Lumia 1020 last year.
