Don't you wish there was an app that you could download to your iOS or Android device that could actually help you get more from your built-in battery? Now there is.

Called Carat, this is the first app that can give you personalized battery life-saving recommendations. The app works by collecting metrics from your device and periodically sending them to the cloud in anonymized form.

There they are combined with data collected from other users and what's described as "cutting-edge algorithms" are used to number-crunch the data and come up with personalized steps to help you use less power.

Carat will tell you which apps are battery hogs, and which are bugs --- which also use up a lot of battery. Being a hog or a bug does not make an app 'bad', but a user trying to improve their battery life can use these designations to adjust their behavior.

And before you start thinking that Carat is itself be a battery hog, it's worth bearing in mind that it doesn't need to run continuously in the background. You just have to run it periodically so it can send the data back to the servers and generate personalized recommendations for your particular device.

Nothing that is collected identifies you personally.

Carat has been developed by a team of scientists from the UC Berkeley electrical engineering and computer science department's Algorithms, Machines, and People Laboratory (AMP Lab).

The app is free and available both for iOS and Android devices.

If this app doesn't allow you to get satisfactory battery life out of your iOS device then I've compiled a list of battery saving tips that are guaranteed to help you squeeze precious minutes out of your device.

These tips work for both the iPhone and the iPad.

  • Using "Kingsoft Battery Doctor" for iPod touch, but...

    ...have no way of knowing if it will double the life-span of the battery. The battery usage tips are (mostly) the same too.

    I like the idea of Caret using information from other devices to better analyse what works and what doesn't.

    What's needed now is a test between battery apps to determine which benefits your battery the most.

    • Apps will not "double" battery life

      All they can do (at the best) is guide you into disabling useless services that are turned on by default to minimize power usage.

  • So it Just...

    Tells you what to turn off (like wifi when you don't need it), which apps use the most power, and to reduce your screen brightness etc. I already know that stuff. ICS has a nice screen that shows which apps are using the most power. What does it do automatically to help manage battery use?

  • Battery Life

    This is simple one. I always de-sync my phone from hand-shaking with the time server. This can save quite a bit of battery life.

  • Battery Saver

    Apps like Juice Defender and Easy Battery Saver help a lot by disabling data and wifi when you're in standby. I have seen a consistent 25%+ improvement.
