How old is your phone ?
I ask as it can take a few discharge and recharge takes to reach optimum output.
How long does the phone last between charges.
Try topping up regularly.
Try not to let it go below 20%
How is signal strength where you live as fringe coverage may mean the phone is having to work harder to maintain connection.
Check your phones battery specs as that should highlight what is using the battery.
Put the phone in Safe Mode which disables any downloaded apps and leaves just the stock ones working which can help to highlight if a rogue app is draining battery.
Battery life is a subjective topic as we all have our phones set up differently, use different apps which again are set up differently and use location based apps along with different signal strengths and use our phones differently.
If necessary a Samsung Service Centre can run a diagnostic on the phone.
