Why does my iPhone's Screen Time show abnormally high usage compared to battery health data?

Why is my screen time abnormally high? Last week and two weeks ago it recorded an average of 24 & 23 hours respectively which is impossible since I sleep at least 9 hours every night. This week it’s at 15h, while in the battery health tab it’s only about 4hrs per day, which is usually what my screen time averages to be. Idk when this issue started but all the data for the last few weeks is very weird and I’m wondering what could be wrong.
