Samsung Galaxy S9 Battery Drain is ridiculous.

[Android Central Question]

I updated my phone three days ago and ever since I've notice that Android System has been consuming up to 37% of my battery usage with my last full charge being four hours ago. Is this an issue relating to the recent update?

Being it a big update , try clearing cache in recovery see if that helps otherwise might want to try factory reset to clear out any old files .
