Hi, we suggest you that you can view your battery usage in settings and also please run the diagnostics in Samsung members app to check the device battery health.
If needed, you can shorten the screen timeout to save battery life.
From Settings, search for and select Screen timeout.
Tap Screen timeout again, and then select your desired option.
Choose 15 seconds to save the most battery life.
The screen timeout is set to 30 seconds by default.
Also, we recommend you to optimize the battery usage time by setting Adaptive battery or adding unused apps to sleep depending on your usage pattern.
