If so how much does it cost?

As the phone is so new I don’t think anyone has even access to the battery for it. I would recommend you get it serviced under warranty as I’m sure this would be covered.

It is a new phone, why you should replace a new battery now?

Not, i’ve been have an issue with the battery (bloated). Razer Support : they doesnt have battery replacement service program and offering me to replace with new unit (free if claimed under warranty or cost u almost same as you bought new phone)
