Hi balbonoliverken,
If you feel like the battery drains during using specific apps, we would suggest you test how much the app drains after using it for a certain time.
We would suggest you clear the background apps, and check how much battery is consumed from 100% after using the app for a certain time (e.g. 30 mins or 1 hour.)
Please show me a screenshot of the battery usage after testing.
Settings > Battery > Three dots on top right > Battery usage.

If there are battery drain issues in sleep mode, please kindly follow the steps below and show us the screenshots.
1) Charge the phone to 100% before going to bed > remove the charger > Clear all apps in recent app list >  turn off screen > the next morning before using the phone, please screenshot the two pages:
a) Settings > Battery
b) Settings > Battery > ""Advanced battery usage"" (tap the battery icon to access)
Thank you 🙂
