Recently Neowin has been providing us with latest information of the upcoming Windows Technical Preview Builds in the 986x Series, and they have revealed more information today.
Their latest report says that Microsoft will include the Windows Phone “features” namely Battery Saver and Data Sense bundled in with the 986x series of builds of the Technical Preview. It is unfortunate that they have not confirmed these actually coming to the public build of Technical, which indeed we will have to wait for.
According to the report, Battery Saver will do the exact same thing that it does on Windows Phones like cutting down screen brightness, stopping apps running in background (unless they have permission to run) and let you monitor which apps are taking most of your battery.
Similarly, Data Sense will do the exact same thing it does on Windows Phones like showing you which of you apps take most of your data and allows you to put settings such that will restrict background data, etc. and is useful if you are on a metered connection.
