LIneage OS 15.1 battery drain

[hazard16]

Hello, this is my device:
OS: Lineage OS 15.1-20180813
Phone: ONEPLUS A5000
Android version: 8.1.0
Recovery: TWRP 3.2.1-1

I switched from last Oxygen OS to Lineage OS 15.1. I have noticed that this system drains battery 3x faster than last version of Oxygen OS (with the same applications and same usage). With Oxygen I had to charge battery once per 2-3 days. With Lineage 15.1 I have to charge battery once per day.
Does anybody face this problem and solved it? Do you have any advices?

Thanks.
