Battery life is different on the WF compared to the Widget on the Garmin watch.

Is it a native one WatchFace or some from the IQ Store?

In case of the IQ Store, his author might implement a truncating of the float value, whereas the native widget makes a rounding instead. E.g. 73.0-73.4 raw values will be both truncated and rounded as 73; 73.5-73.9 raw values will be truncated as 73 but rounded as 74. So, in fact, you will see a difference not always but only half of the time.

Sometimes it may help the author to save precious resources on watches with a very limited hardware

This is a known issue (probably some kind of a bug) that the numbers we see in the top of widget page and the number we see via the CIQ api (that can be then displayed by watchfaces or apps or even CIQ widgets) are different.

So there is no way to fix this kind of error yet?

Thanks

This is the development of the watch face (ciq), which I do. I just wanted to know if this happens to everyone or is it just me. But as user: locsy (Gavriel) already wrote to me, it seems to be a known bug.

Now they need to know if there is any solution for this or not?

This may be more of a rounding issue than a bug.  Let's say the battery is 73.51%  For display, is it rounded up (74%), or is just the integer part used (73%)

The same could happen with "days" (10.6 days could show as 10 or 11 days based on rounding), but there is the added variable, that what's shown is based on what the watch is doing at that time.  If you are on the watch face, and you scroll and see "days", it can be VERY different if you are in something like the Run activity, and from there go to the watch face, where instead of days, the battery life is shown in hours

Actually, it means I wouldn't worry about it.  On some devices, you don't even see the decimal part of the battery percentage in CIQ but the firmware might.

Ok, thanks for the clarification, I'm getting it out of my head.
