Windows 10 Adds Battery Saver Feature

Posted by timothy on from the perpetual-frontier dept.

jones_supa writes In past builds of Windows 10 Technical Preview there has been an interesting feature called Battery Saver, but for the time being it has been just a mockup. In a leaked build 9888, the code is now in place. Battery Saver, as the name implies, will help your mobile device make the most out of your battery. This feature works by limiting the background activity on your device when the mode is activated. You can turn the feature on any time but there is also a setting to have it automatically turn on when the battery capacity goes below a user-defined percentage. Considering that this build was not supposed to make its way out of Redmond and that the company is not releasing any new builds this year, this may be the best look we get until the Consumer Preview arrives.

    so, I have had this annoyance with android forever.
    there are multiple battery saver things that trigger saving features when I'm below percentage - but its obviously too late then!!

    the trigger needs to activate when the RATE OF DRAIN exceeds a particular threshold

      ^ This.

      So this. 100x this.

      The logic behind all these battery savers is ridiculous.

      "Your battery is now at 20%" - Let me warning you every 5 minutes that it's low, consuming even MORE battery. Once is enough, thanks.
      "Your battery is now at 10%" - Let me tell all applications about this so they can all send their data to the "cloud" all at once, draining it EVEN FURTHER!
      "Your battery is now at ... " - Phone turned off due to too many bells and whistles about your battery being low!

    No - it's Microsoft's incarnation of Apple's AppNap feature.
    (think of it as an aggressive and automatic version of the *nix renice function with a suspend feature latched onto it.)

    Actually, it's not. AppNap enables the OS to wake up and have apps refresh their state (enabling more functionality). Battery Saver on the other hand clamps down on apps which periodically refresh when battery is low because a dead battery is useless to the consumer.
