I think this issue started only after Jelly Bean.I'm not sure though.
THE LAG:
-> After exiting an heavy app using Home button, such as Facebook if you swipe left or right there is a minor shutter for 2-3 swipes.
After that the UI becomes fluid.
-> If you are updating/installing many apps and your notification bar is constantly being updated, navigating in home screen is very laggy.
-> If you get a message like "Wifi Connected" or "Message delivered to XYZ", during that brief moment the UI lags.
THE SOLUTION (Using Nova Launcher):
1) Enable Labs in Nova launcher.
How: While in Nova's settings menu, hold volume down for 2-3 seconds. You'll see a toast notification letting you know that Labs was successfully enabled. Similarly, if you wish to disable the new menu for any reason, just hold volume up for 2-3 seconds.
2) Go to labs.
Tick the following two settings:
a. UI Lock
b. Widget Image Cache
That's it. Enjoy the UI smoothness like iOS.
I've tried it for whole day and the battery isn't affected at all. No sacrifice in performance either.
