I would like an answer to this question also. Surprising and a little disappointing that the question is two years old and there is no response.

Same here. Most probably very easy to implement. What are you waiting for Garmin? please add the watch battery status in Connect and Connect IQ
I've merged several threads into this main thread. Note some of the suggestions posted previously. For me I find it very easy, with the watch face set to show battery status (epix Gen 2), to just glance at my watch. But I understand if people have their reasons to need it on the Connect app.
Its simpler to see on a phone layout (with notifications) than to scroll through minute text of multiple screens on the watch.
It is not that complicated. Just push the left button in the middle of your watch for a few seconds and percentage and days left just pop up.

It would be nice to get it through the app so that in the case of charging the watch you could look at your phone and know when it's through charging. And another case it would be good when you're going through your connect and stats to be able to look at it and go oh I see my battery is down to 20 30% or whatever and plug it in and charge it when appropriate.
But thank you for the tip it is useful.
