Carat For iOS Improves Battery Life By Identifying Buggy Apps

You'll be surprised by how many apps are using battery life unnecessarily. Use Carat to find them.

If you’re an iPhone user who plays Angry Birds and watches YouTube videos all day long, you probably think your handset’s battery life is terrible. In reality, the iPhone often provides you with a lot more energy than many rival smartphones, and as for the iPad, well, no other tablet beats it when it comes to staying awake.

But there are some things you can do to make your battery life even better. In addition to obvious fixes — like turning down your brightness when you don’t need it to melt your retinas, or killing apps like Skype that constantly run in the background — identifying buggy apps that might be using battery unnecessarily could make a huge difference. And Carat for iOS helps you do that.

Carat isn’t like other battery management apps, which simply tell you how much battery life you’ve got left for certain tasks. Instead, it identifies “bugs and hogs” — apps that may be doing things in the background that they don’t need to be doing. For example, a simple note-taking app shouldn’t use too much battery at all. But if it’s got a bug somewhere and it continues to activate your GPS while it’s running in the background, there’s a good chance you’re battery will drain much quicker than it should.

Carat detects these issues, and even tells you how much battery life you could save by killing those buggy apps. It also identifies apps which don’t have issues, but drain your battery anyway until they’re properly closed, like instant messengers or music streaming apps.

It’ll even suggest changes like upgrading your operating system if you’re stuck on an older release, and how much battery that could save you.

According to TechCrunch, Carat was developed by a team of “top-notch” M.S. and Ph.D scientists from UC Berkeley’s Algorithms, Machines, and People Laboratory (AMP Lab):

Carat wasn’t built to make money. It’s the consumer product of cutting-edge battery science and a way for the team to collect more anonymous, privacy-respectful data for research that could make all our devices last longer.

Try Carat out for yourself and see what you think. It’s completely free, and its results could just save you a whole lot of wasted battery life.

    This app got terrible reviews on the app store, some people said it (carat) was a battery hog and buggy itself.

    Yeah this app isn’t ready for prime time yet. Its buggy (crashed three times in three attempts), and says I need to update the iOS version I’m using when I’m using the most recent version.

    Sorry, can’t get behind any app made by a developer who believes in “Karma” to the point of actually putting it in the app.  It shows bad thinking and thus not someone I would trust my battery life to.

    Yeah, this app murdered my battery. A little ironic, don’t you think? Deleted.
