Using 30% overnight is not unusual especially if it is doing housekeeping tasks.

Always charge your phone all night every night. That way optimised charging (circled below) kicks in to protect your battery health. It may take 2 weeks for it to learn your sleep pattern.

Do not leave off charge overnight or it cannot learn.
