Below solutions may or may not help, but they are worth trying
1. Turn off background data for all the apps for some time.
2. Put the phone on "always on stamina mode" with stamina level set to device performance preferred
3. Turn off adaptive brightness, turn off smart back light control & turn off image enhancement
4. Turn off smart cleaner
5. Remove face unlock

After upgrading to 41.3.A.2.213, I faced similar effects.
Battery life is gone for a toss. Screen on time was 2H 52mins to the max.
I performed factory reset and used the above mentioned tricks, post which, my screen on time was 3H 22mins. There seems to be a service which drains the battery badly. I am working on it to find out.
I'm still on .192 but had also very poor battery life after upgrade to .192. For me it seemed to be enough to update Battery Care to a newer version from Apkmirror. The newest version didn't want to install but version 1.2.5.A.6.3 did and I haven't seen any side effects other than increase in battery life.
