Hi @Mike01_k, welcome to our forum and I'm sorry to hear about this. 
The battery can be replaced by an authorized service centre, however I would recommend that we do some troubleshooting first, just to make sure that it's actually the battery that is the culprit.
Is the battery not lasting as long as it used to, or is the device shutting down at random percentage and you can't start it up again?
A good place to start is by using the device in safe mode for a few hours and see how the battery behaves when downloaded applications aren't loaded.
Let me know how it went!
