Battery drain

So i've had alright battery life for a while now. I go to University for 8am and get back at 6pm and would still have high to mid 60% left (with a decent screen on time). Ive optimised everything: disabled apps, force doze (continuously went the entire day only losing 2% with wifi off at summer job), changed my mobile network prefermce casue i dont have data, etc etc.

However, since ive downloaded a software update, found it was called SMR-SEP-2018, my battery has been absolute garbage. Before i was at mid 60% at the end of the day but now im left with 30% max. It dropped from 55% to 42% in an hour with the screen not even on. The same day it dropped from the 42% to 11% in not even 35 mins, with barely 10 mins of screen time.

The only thing thats been fishy is in battery usage the system used like 25% on the same day where it dropped from 42% to 11%. It seems alright with force doze but as soon as my screen is on it drops like a stone.

What could be wrong? None of my settings have changed and i cant find anything else. Im stummped.
 
Silly question. Have you rebooted your phone since the update? Sometimes something as simple as that can put things back to acceptable levels. You could also try clearing your app caches in case there's something going on with updates trying to use previously cached data.

Reboot as in a full factory reset or a simple restart?

Maybe the battery is just getting old.

That's a possibility and the update put just enough strain on it to cause degraded performance. I think it's more likely that a few apps are not playing well with the update and are staying active when they should be sleeping. Keep an eye on your power usage for any indicators.
