The battery in my Razer Blade 15 only lasts around 1.5 hours with only streaming running. I have only had it for a year and a half. Is there a replacement battery and does in fall under warranty? This is the worst battery life I have ever had even compared to my old Alienware and Dell XPS especially considering the premium price paid for the machine. I am in Australia and the only stockist in the Microsoft Store which offers no help when it comes to Razer.
