Default [Q] Why is android system using a lot of battery?

So i have been experimenting with roms/kernels in the past few days and have noticed android system is almost using as much battery as the screen. What causes this? I never had this problem before I rooted. I am currently at 69% and my screen on time is only 1 hour. I have tried many kernels and I can't get any more battery life out of the phone. Other than the obvious stuff, what can i do to get better battery life?

You have to show us the BBS log. (Better battery stats) for wakelocks.

I only get like 16 hours of battery life and I could really care less because even if I was left at 60% when I went to sleep it would need to be charged or I would potentially be left with 20% the next day assuming I had the exact same usage and that isn't comfortable so I charge every night.

Keep in mind your cell signal. You can also switch off mobile data or switch to edge or 3g instead of LTE.
