Excessive battery consumption on latest LineageOS

[DHGE]

Has anyone else exprienced this with the latest LineageOS from March 23rd?

I get <5 projected hours of battery usage with the main user "Android system" <- this is not normal.

Before I got 3 to 4 days projected usage.

I rebooted after power off for some time.

I could get new Gapps. Those I got are from last November.
I could roll back to LineageOS from March 16th.

Anything else?
What do you think?

Seems to be solved

FWIW:
I cleared system and cache partitions via recovery (spared the data partition).
Then flashed the LineageOS again and the latest GAPPs pico in one swoop.

Now I get 5 days of projected usage again.
