On some (older) versions of Android, the JVM (and other components) often read random data from the blocking /dev/random, which has a low entropy by default, causing that some processes block themselves waiting for new data generation with a greater entropy. On newer builds, this problem has been solved, yet depletion of the input entropy pool still seems to slow devices.

So this fix seems to reduce some lag in the Android OS (XDA thread: http://forum.xda-developers.com/showthread.php?t=1987032 )

However, the initial post makes some changes that are 'artificial' which probably affects battery duration, so I just created an app that applies a more natural method based on this post: ( http://forum.xda-developers.com/showthread.php?p=36093065#post36093065 )

It just modifies the system's wakeup threshold to update /dev/random values when the entropy is too low. And it's completely reversible :)

NOTE: To modify the threshold ROOT permissions are required.

    It really reduced much lag of my Galaxy S4. It didn't drain battery so much compared to "Seeder". Thanks for creating such a great piece of software.

    I prefer Seeder over sEFix coz the former increases my entropy pool to 4096 but it only limits me to 3000s (even at 1024)...... Uninstalling till improved... :)
