Carat

PLEASE READ BEFORE INSTALLING

Carat is the first app to generate personalized recommendations for improving your battery life. After observing your use of the device for about a week, it will start to generate reports just for you.

Carat does not use GPS. It never runs in the background. The app uses almost no power.

Thank you!

Ever wondered why your battery is draining so quickly? Just install Carat, open it every few days so it can send data to our servers, and within a week Carat will start recommending Actions (just for you!) and even predicting the improvements you will see. Although Carat cannot measure energy use directly, it infers what apps are responsible using advanced machine learning methods.

And it's free!

As you use your device, Carat occasionally takes measurements and sends them to our backend servers in the cloud, where we apply cutting-edge algorithms to determine what steps you can take to use less energy. By collecting snippets of non-personal data from a large number of devices, Carat does not need to run continuously in the background. Nothing we collect identifies you, personally.

Carat will tell you which apps it thinks are hogs (they use a lot of battery) and which are bugs (they use a lot of battery on your device but not most others). 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.

Carat Features

•  Action List telling you how to improve your battery life and by how much

•  Device information detailing exactly what data we are recording

•  Reports apps that are using lots of energy and whether that is happening on other devices, too

•  Detail views let you dive down into the data

•  Low-overhead sampling requires almost no energy or CPU

•  J-Score tells you how your battery efficiency compares to other users

•  Sharing features let you post/tweet/blog about your experience; more users means more data which means better recommendations for you

Carat started at the AMP Lab, UC Berkeley, in collaboration with University of Helsinki. It is under active development by a team of researchers in the NODES group, Department of Computer Science, University of Helsinki. We are constantly making improvements, adding features, and giving you more knowledge about how your device is using energy. Remember, knowledge is power!

请安装必读

克拉是第一个应用程序生成提高你的电池寿命的个性化建议。观察你的设备使用了经过约一个星期的，它会开始产生只为你报道。

克拉不使用GPS。它永远不会在后台运行。该应用程序时几乎不耗电。

谢谢！

有没有想过为什么你的电池耗尽如此迅速？只要安装克拉，打开它每隔几天，因此它可以将数据发送到我们​​的服务器，并在一周内将克拉开始推荐操作（只为你！），甚至预测你会看到改善。虽然克拉不能直接测量能源使用，则推断采用先进的机器学习方法哪些应用程序负责。

而且它是免费的！

当您使用的设备，克拉偶尔进行测量，并将它们在云中，我们运用尖端的算法来确定哪些步骤，你可以拿去用更少的能源发送到我们​​的后端服务器。通过收集从大量设备的非个人数据的片段，克拉不需要在后台持续运行。没有我们收集识别你个人。

克拉会告诉你哪些应用程序认为是猪（他们使用了大量的电池），哪些是错误（他们使用了很多电池的设备，但不是大多数人的）。作为一个养猪或错误不会使应用程序“坏”，但用户试图改善他们的电池寿命可以使用这些名称来调整自己的行为。
