BatteryInDays - function

Jack

Hi,

where can I find the sample code for proper batteryInDays function?

I would need to display battery life in days.

Thank you

    So I did the following:

    I created the 4.1.0-beta1 SDK.

    New test WatchFace for device venu2system5preview (because for F6 it is not released yet.

    I also copied the code provided by peterdedecker, Thank you.

    And the result is a picture name - Test.

    What is Toybox.pro batteryInDays?

    Test

    If you are using a System 5 preview device and that doesn't work

    It works for me in the sim, with either the Fenix 6 System 5 Preview or the Venu 2 System 5 Preview.

    I created a simple datafield with:

    function compute(info as Activity.Info) as Numeric or Duration or String or Null {
      return System.getSystemStats().batteryInDays;
    }

    it is likely that the function isn't working yet even in the sim

    That seems like it would be a bug in that case (i.e. if "System.getSystemStats() has :batteryInDays" returns false when using the 4.1.0 beta and a System 5 preview device.)

    But it isn't the case.

    It looks like your battery drawable is positioned partially offscreen (or part of the text is offscreen because you have so many decimals)

    When I call System.getSystemStats().batteryInDays in the sim, I get 5.00. In your case, it seems that the 5 is offscreen.

    The reason you're getting a box instead of "d" is because your drawable must be using a numerical font (in which case "d" is unavailable). If you want to print "d", you'll have to use a smaller, non-numerical font.

    I would just insert some System.println() statements in your code so you can satisfy yourself that the correct code is being called, then you can work on the positioning/font/cosmetic issues separately.

    The reason you have so many decimals in your output is because of this suggested code elsewhere in the thread:

     var batteryViewString = Math.round(myBattery).toString();

    If you just want an integer number of days, you can use something like this:

    (with truncation / round down)

     var batteryViewString = myBattery.toNumber().toString();

    (with rounding to the nearest integer)

     var batteryViewString = Math.round(myBattery).toNumber().toString();

    Or you could adjust the code to just print 2 decimals, if that's what you want. e.g.

     var batteryViewString = myBattery.format("%.2f");

    Hi, could anyone provide me a code that calculates battery discharge in days and is compatible with CIQ  3.2 ?

    I can't wait that long until the last SDK is ready to support it ...

    Thank you

    Days would be the integer part, and hours, the converted decimal part.

    ex:

    1.5 = 1 day, 12 hours (.5x24)

    3.33=3 days, 8 hours (.33x24)
