28 January 2010—Power drains on smartphones are becoming a bigger problem as users want their mobile devices to work faster and do more. Now researchers at the University of Michigan have come up with an application called PowerTutor, which lets you monitor your phone's power usage and compare the efficiency of one app to that of another. Released late last year, the app, currently available only for Google's Android phones, also gives mobile-app developers a chance to streamline their programs.

You’d expectthe longest and most costly phase in the lifecycle of a software product to be the initial development of the system, when all those great features are first imagined and then created. In fact, the hardest part comes later, during the maintenance phase. That’s when programmers pay the price for the shortcuts they took during development.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
