Galaxy Watch 4 Battery Life

Ever since the software update last week I have had to charge my battery AT LEAST TWICE per DAY!!!

I had my watch fully charged at 8:45 this morning and it's already at 75% (3 ½ hours later). At this rate I will have to fully charge it again before I go to bed.

I would LOVE to upgrade to the Galaxy Watch 6, but I am still paying on this one. Is there any way to get an early upgrade without having to pay off this one upfront?
