I am facing tremendous amount of battery drain issues with my S10e. I am on July update currently.
--On Android 9 November update, my SOT was 5 hours 30 mins average with 12+ hours of stand by time
Below are some steps that I performed to limit the battery drain, but these helped very little
1. Wipe cache partition
2. Go to each app's info -->
i. Mobile Data --> disable - Allow background data usage
ii. Battery --> disable -Allow background activity
3. Disabled chrome, because it hogs on resources & battery
4. Disabled - Auto Sync Data
5. Disable/Uninstall social media apps
6. Used sleeping & Deep sleeping apps.
7. Always on Dark mode.
After these steps, I hardly reach SOT of 3 hours & 25 mins with 8 hours of stand by time (approx)
