Bug: Screen using excessive battery

[Jeb]

My screen is using an excessive amount (≥47%) of my battery usage on the Asus Zenfone 6.

Android 10, Build Number "...121"

Screen on time calculation is vague for battery performance. If don't use my phone much, I get 3-4 hours of SOT over 3 days in single charge.
If your most uses on outdoor/bright light, then most probably screen is always on high setting. Then, It looks normal.
