Why is my android system battery usage so high?

[Puttdawg]

My usage with android system stands at 27%, which I've read to be very uncommon. It has given me a shorter battery life and was wondering if someone could tell me what the issue is.

Welcome to Android Central! What device is that? Does it persist after a reboot?

I rebooted. After last night, it decreased to 17%. I'm not sure if it could be lowered more, but I rebooted it last night before brd

It can depend. If you don't use your phone a lot, meaning it is idle more often than not, then the Android OS can be at the top of the list.
