I have a Razer blade 2015. The battery says unknown remaining or gets stuck on a certain percentage. It will still show if it's charging it not, but the battery level display is fixed. This started happening after the computer crashed while gaming. It still crashes in the division and Diablo but hasn't crashed in league of legends. It has always gotten pretty hot while gaming, CPU temps around 90c but it never effected performance until the crash and battery issue.
