@ste49 I would agree with @Glenntech 's post. We all use our phones slightly differently and cannot be definitive but on average Battery on your Device should last around a day. If you are a heavy user of power intensive apps that is obviously going to have an impact. I guess you are asking this question because you have not been that impressed with your Battery life lately.
For general optimisation only have connections such as Bluetooth,GPS and Wifi running when they are needed and put apps which are not used regularly into sleep Mode.
Software support though for the S9 ended over a year ago https://www.xda-developers.com/samsung-ends-software-support-galaxy-s9-galaxy-s9-plus/ Therefore you may to consider a new Device at some pont.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
