Can you clarify what if any troubleshooting guides you've tried ?
A phone's battery will decline over time due to amount of times it is charged and discharged however unless your battery has developed a fault that amount of loss seems excessive.
First look in your Battery and Device Care to see what's using the battery in regards to apps and if one seems high in percentage then take some action.
If you wish charge the phone to 100% and then use the phone normally as you would do until it reaches approximately 15% and then in the Battery and Device Care Section tap on Battery to show the apps and then screenshot that whole page with also using the scroll capture option to catch all the apps and include the top status bar of the phone and post your results here so we can get a handle on what's going on. 👍
Also use the Optomise Button as this can help.
Other generic troubleshooting guides are >

The advice I offer is my own and does not represent Samsung’s position.
