How to improve or extend the battery life of your Razer Blade
Fully charge your Razer Blade. Go to "Power" settings then adjust both the "On battery power, turn off my screen after" and "On battery power, put my device to sleep after" options to "Never". Unplug the power adapter and let your Razer Blade idle until the battery drains completely. Charge your Razer Blade until it reaches 100%.
