S7 Battery life is drained very quickly by Android OS and - System

[AC Question]

The last two weeks or so my Samsung S7's battery has been draining very quickly, when I go into Battery Usage, "Android System" and "Android OS" have often used up to 40%.

Is there anything I can do to fix this, or something I can switch off to prevent it from chomping so much battery?

Try first a Power Off and Restart. If no go, try a Cache Partition wipe.
If still no go, get back to us.
