Jelly Bean resource Usage I have a phone with 512MB of ram. The company has launched the Jelly Bean update for the phone. Currently my phone is running Android ICS 4.0.4 which has alot of lag and frameloss issues, So I am thinking to update to JB. However I am concerned about the memory usage of JB. 
So my question is:

Whether JB uses more ram than ICS?
Jelly Bean uses pretty much the same amount of RAM. There's not much of a difference. 

Performance-wise, Jelly Bean is much better. It will even make phones with 512MB RAM feel smooth, with some lag still, cause you know.... 512MB RAM, but it should feel much better than ICS.
