Galaxy Watch Series devices battery widget suddenly not work

[truelies]

I didn't do anything on the watch. Suddenly the battery widget has problem, the numbers not change any more, while the green progress bars are showing correct percentage.

@truelies The correlation between the bars and percentages look correct to me. 

How far are the numbers off? 

[truelies]

The percentages never changed after I restarted the watch.

Sorry didn't realize that there were 2 screenshots. Did it recover once the watch connected via Bluetooth to the phone?

[truelies]

No, it always connected

In other words, your watch was charged to 100% but is only showing 80%?  Try clearing the watch cache. 

[truelies]

The number always showing 80%, not update. Cleared cache, still has this problem

May I suggest that you remove the battery tile from the watch and and use a watch face where you can add a battery complication and see how that goes?

[truelies]

Yea, I tried remove and add back the battery widget. It was showing correct percentages then again not change.

I meant, just remove the tile completely for a little while - there may be something wrong with the widget.  Use a watch face with a battery level complication, like the one I am using. 

 I don't actually like the tile, as when you tap it, it won't show you the battery details.  When I tap the complication on my watch, I can see how many more hours my watch is expected to last before I have to charge it and the usage statistics.  So, unless you really need to see your phone's battery level from your watch (and I can understand why you would with the small battery pill), don't use the tile.  There may actually be a defect in the tile, so put in an error report.  I added the tile to my watch and, so far, it's showing the correct levels of both my watch and phone.
