Hello @Talukder32 

Can you elaborate a little more as to what's happening with your phone and it's battery please. 👍 

Your phone would have a 24 Month Manufacturing Warranty as standard.

Unless youve added Samsung Care+

You may have cover via any other relevant insurance cover such as Home Contents Insurance and some Bank Accounts provide cover as a perk of the account. T&C's would need to be checked. 

You can look at what's using your Battery via the Battery and  Device Care Section in your phone's settings.

And there are other troubleshooting steps you can use such as clearing the phone's System Partition Section Cache Files ,and you can use Safe Mode to help determine if an app or theme or launcher is depleting the battery.

• 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 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. 
• Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 

A very last resort can be a Factory Reset.

Take into account that over time as a phone's battery is charged and discharged this reduces the effectiveness of the battery.

A Samsung Service Centre can assess the phone too.

If I can be of any further help then please don't hesitate. Take care.  😎
