Worse Battery Life

Hi everyone, I would just like to find out if anybody else has experienced a sudden downgrade in battery life. My Galaxy Watch 7 44mm which I got in May this year has suddenly been dropping 30+% overnight even while having Power Saving on. This started happening after I had to extend the battery over the weekend because I did not have my charger.

I have resorted to factory resetting it but have not yet set it up again.

Please let me know if anyone else has been experiencing this😁
