Saw lot of posts regarding poor battery life of s20 fe. Considering the phone is equipped with a 4500mah battery, the backup is below satisfactory. What i notice is when phone is on use it mostly drains similar to other phones (oneplus 7t) but the idle drain is very high. 7t drains only 2 or 3 % overnight but s20fe drain is about 8-11%(that too with bixby routine for power saving on aod off, auto brightness off ). 
I think this is to do with the inefficient exynos 990. Can other exynos 990 user share your idle drain percentage. Can samsung improve battery life???????

Idle is 3 % for me after 8hrs sleep, it was between 5% in oneui 2.5, but active is a bit higher. So thats part is needed to get fixed
