This is a little trick to make your Nexus appear faster. It does NOT make your phone faster but it just gives it the appearance of being super super quick.
Go to Settings>About Phone
Click on Build Number multiple times until it says you have now become a developer
Go back and you should now see developer options above About Phone
In developer options you should see Window Animation Scale, Transition Animation Scale and Animator Animation Scale
These should be set to 1x, set them to .5x
Now all the animations will be half the time giving the phone a even faster feel
You can set the animations to off but this ruins the experience IMO
P.S if you ever wanted to get rid of the CRT TV off animation when you lock your device. Turning off animations and restarting your phone will get rid of it.
