Hello 👋 @Mohamadd
When a phone is first purchased the battery won't be fully optimised until it has been charged and discharged a few times.
Also it would be in the learning phase for approximately 14 days.
Take into consideration it will be probably settling down after updating it, and downloading your information ,and you'll be using it more regularly as you tweak it's functions and features etc.
In the Device Care under battery there is a section that shows what apps are using the battery. If one is heavy using them think about sleep and deep sleep options.
May I suggest to perform a forum search as you may find already existing threads with help and advice within in regards to battery tips.
There is also an optimisation tool found in Device care.
A known troubleshooting step is
- Clear Cache Files from the phone's System Partition Section > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port or a usb-c to usb-c phone to phone set up to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's }
If i can be of any further help please don't hesitate to ask 😎

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