How long does the S9+ last on a full charge?

After 2 weeks of regular usage I put it to the 30 day test. Everytime the battery was almost dead I took a screenshot. These screenshots were assembled into a video.

Mostly web browsing, some YouTube, no gaming; approximately 10 hours usage per day, screen brightness ~40%.
