Surveys don't provide perfect information. People may say they want better battery life because that's the only thing they can think about their phones that could get better. 10 years ago if you asked people what they wanted in cell phones they would have said "smaller, thinner flip phones please". Very few people would have asked for a smart phone that was was easy to use and with no physical keyboard. In other words, asking customers what they want is often a terrible way to figure out what to build next. Also, the type of person willing to respond to a survey like this is likely already an outlier and more prone to running into the limits of what their battery will allow them to do. If people truly wanted better battery life they would buy huge cases with big batteries built into them. I know very few people who own one of them.
