Silly Question:
When Yarbo is out mowing your field 
Does it affect Yarbo’s Core battery at all if you prolong the use of the app while viewing Yarbo’s Live Camera feed and keeping track of it’s location? 
I haven’t noticed a difference either way.
Yarbo has a very big battery. I wouldn’t worry about it.
Someone once asked me if using the radio drained the battery in my Teslas any faster. He was a network engineer. I was quite surprised at the question, but just told him no, it doesn’t make a difference if the radio is on or not.
I’m sure it has some impact, but not enough to worry about.
It will not have a significant impact on the Core battery. You can continue using the app to view the Live Camera feed and monitor Yarbo’s location without worrying too much about additional battery consumption.
