Difference between trial and paid in regards to Wear OS battery?

I did the trial for 13 days without an issue on the battery life of my Wear OS (Fossil), with battery consumption at only about 30-35% for the duration of sleeping. Purchased the unlocked version 2 days ago and last night my watch went from 100% to 5% by the time I woke up 6 1/2 hours later. I haven’t made any changes to the app, but didn’t know if the unlocked version makes changes after unlocking the full app?
